Rigorous Quotes & Sayings

In some ways, a novel isn't as structurally rigorous as a screenplay or a TV show, which have finite real estate. In a novel, you can more deeply illuminate a character's interior and get away with digressions. — Howard Gordon

Theologians, and religionists in general, start with a fantasy premise and then proceed to apply rigorous formal logic to tease out its implications. Stark himself points out that "theology consists of formal reasoning about God." This is admirably exact. Theologians, beginning with a wished-for creation of their own minds, analyze that creation's characteristics by rigorous application of the principles of formal - that is, deductive - logic. — Andrew Bernstein

The Working Song
by Breton Braley

Oh, we're sick to death of the style of song
That's only a sort of a simpering song,
A kissy song and a sissy song
Or a weepy, creepy, whimpering song.
So give us a lift of a lusty song,
A boisterous, bubbling, boiling song,
Or a smashing song and a dashing song,
Oh, give us the tang of a toiling song,
The chanty loud of the working crowd,
The thunderous thrall of a toiling song!

Ay, sing us a joyous daring song,
Not a moaning, groaning, fretting song,
But a ringing song, and a swinging song,
A rigorous, vigorous, sweating song.
We have had enough of the gypsy song,
Which is only a lazy, shirking song,
So toughen your throat to a rougher note
And give us the tune of a working song,
A tune of strife and the joy of life,
The beat and throb of a working song! — Berton Braley

Even as rigorous a determinist as Karl Marx, who at times described the social behaviour of the bourgeoisie in terms which suggested a problem in social physics, could subject it at other times to a withering scorn which only the presupposition of moral responsibility could justify. — Reinhold Niebuhr

In my own field, I know that solid science can easily be done with ethics and compassion. There's nothing wrong with compassionate or sentimental science or scientists. Studies of animal thought, emotions, and self-awareness, as well as behavioral ecology and conservation biology, can all be compassionate as well as scientifically rigorous. Science and the ethical treatment of animals aren't incompatible. We can do solid science with an open mind and a big heart.
I encourage everyone to go where their hearts take them, with love, not fear. If we all travel this road, the world will be a better place for all beings. Kinder and more humane choices will be made when we let our hearts lead the way. Compassion begets compassion and caring for and loving animals spills over into compassion and caring for humans. The umbrella of compassion is very important to share freely and widely. — Marc Bekoff

Hugely enjoyable and insightfulGosling has produced the perfect combination of rigorous research and lightness of prose to create a book that will transform every reader into a super snooper. — Richard Wiseman

Thousands of Americans, Englishmen and Frenchmen have visited Germany during the months after the national revolution and were able to testify as eye-witnesses that there is no country in the world where law and order are better maintained than in present-day Germany. That there is no country in the world where person and property are held in better respect than in our own, but that there is perhaps also no country in the word where a more rigorous fight is put up against those who believe that they are free to let loose their lower instincts to the detriment of their fellow-beings. — Adolf Hitler

She will try to find the nice way to exercise intelligence. But intelligence is not ladylike. Intelligence is full of excesses. Rigorous intelligene abhors sentimentality, and women must be sentimental to value the dreadful silliness of the men around them. Morbid intelligence abhors the cheery sunlight of positive thinking and eternal sweetness; and women must be sunlight and cheery and sweet, or the woman could not bribe her way with smiles through a day. Wild intelligence abhors any narrow world; and the world of women must stay narrow, or the woman is an outlaw. No woman could be Nietzsche or Rimbaud without ending up in a whorehouse or lobotomized. Any vital intelligence has passionate questions, aggressive answers; but women cannot be explorers; there can be no Lewis or Clark of the female mind. — Andrea Dworkin

In the Principia Mathematica, Bertrand Russell and Alfred Whitehead attempted to give a rigorous foundation to mathematics using formal logic as their basis. They began with what they considered to be axioms, and used those to derive theorems of increasing complexity. By page 362, they had established enough to prove 1 + 1 = 2. — Ted Chiang

Rigorous financial discipline that, together with monetary stability, ends once and for all the boom and bust that for 30 years has undermined stability — Gordon Brown

This experience sufficiently illuminates the truth that free curiosity has greater power to stimulate learning than rigorous coercion. Nevertheless, — Augustine Of Hippo

In college, in the early 1950s, I began to learn a little about how science works, the secrets of its great success, how rigorous the standards of evidence must be if we are really to know something is true, how many false starts and dead ends have plagued human thinking, how our biases can colour our interpretation of evidence, and how often belief systems widely held and supported by the political, religious and academic hierarchies turn out to be not just slightly in error, but grotesquely wrong. — Carl Sagan

Your attitude is perhaps a little unnecessarily rigorous, suggested Jack. — Robin McKinley

The exaltation of human reason and its capabilities, a commitment to rigorous and rational debate, a promotion of intellectual inquiry and scholarly exchange
all sponsored by the Church
provided the framework for the Scientific Revolution. — Thomas E. Woods Jr.

Agriculture probably required a far greater discipline than did any form of food collecting. Seeds had to be planted at certain seasons, some protection had to be given to the growing plants and animals, harvests had to be reaped, stored and divided. Thus, we might argue that it was neither leisure time nor a sedentary existence but the more rigorous demands associated with an agricultural way of life that led to great cultural changes. — Charles Heiser

According to the most rigorous estimates, the cost to save a life in the developing world is about $3,400 (or $100 for one QALY). This is a small enough amount that most of us in affluent countries could donate that amount every year while maintaining about the same quality of life. Rather than just saving one life, we could save a life every working year of our lives. Donating to charity is not nearly as glamorous as kicking down the door of a burning building, but the benefits are just as great. Through the simple act of donating to the most effective charities, we have the power to save dozens of lives. That's — William MacAskill

Men are not narrow in their intellectual interests by nature; it takes special and rigorous training to accomplish that end. — Jacob Viner

The majority of the employees here are civilians," explained my Alderman guide/protector/companion/would-be-executioner as we strode without a word to the security guards through the foyer towards the lifts. "They conduct themselves within perfectly standard financial services and regulations. There is one specialist suboperational department catering to the financing of more ... unusual extra-capital ventures, and the executive assets who operate it have to undergo a rigorous level of training, psyche evaluation, personality assessment, and team operational analyses."
We stared at him, and said, "We barely understood the little words."
"No," he replied, "I didn't think you would. — Kate Griffin

Mathematics is not arithmetic. Though mathematics may have arisen from the practices of counting and measuring it really deals with logical reasoning in which theorems - general and specific statements - can be deduced from the starting assumptions. It is, perhaps, the purest and most rigorous of intellectual activities, and is often thought of as queen of the sciences. — Christopher Zeeman

Film schools are not rigorous enough. They let things get by and kids get out there and they think they are saying something and doing something. — Rob Nilsson

We will also have a more rigorous approach to professional development and managing unsatisfactory performance. — Jay Weatherill

RIGOROUS HONESTY Who wishes to be rigorously honest and tolerant? Who wants to confess his faults to another and make restitution for harm done? Who cares anything about a Higher Power, let alone meditation and prayer? Who wants to sacrifice time and energy in trying to carry A.A.'s message to the next sufferer? No, the average alcoholic, self-centered in the extreme, doesn't care for this prospect - unless he has to do these things in order to stay alive himself. TWELVE STEPS AND TWELVE TRADITIONS, p. 24 I am an alcoholic. If I drink I will die. My, what power, energy, and emotion this simple statement generates in me! But it's really all I need to know for today. Am I willing to stay alive today? Am I willing to stay sober today? Am I willing to ask for help and am I willing to be a help to another suffering alcoholic today? Have I discovered the fatal nature of my situation? What must I do, today, to stay sober? — Alcoholics Anonymous

To arrive at a place called Mastery, you must commit to daily and rigorous practice. Enjoy practising your craft for its own sake without turning your attention to your ultimate destination. Understand, once and for all, that the journey is as important as the destination. — Robin Sharma

I think science has a better story to tell than anyone else has been able to tell and that's because it's based on the rigorous winnowing that science and scientists are always doing in order to find out what's really happening. I think it's really good to encourage generally our ability to tell stories and that's a great skill that we come by naturally, so I'm excited about that. — Neil DeGrasse Tyson

It bothers me when the Hollywood elite are all so against people having guns and want rigorous gun restrictions. — Alana Stewart

Not even Pearl Young, the NACA's first female engineer and the founder of the agency's rigorous editorial review process, left behind research with her name on it. From — Margot Lee Shetterly

Faith is clearly not enough for many people. They crave hard evidence, scientific proof. They long for the scientific seal of approval, but are unwilling to put up with the rigorous standards of evidence that impart credibility to that seal. What a relief it would be: doubt reliably abolished! Then the irksome burden of looking after ourselves would be lifted. We're worried - and for good reason - about what it means for the human future if we have only ourselves to rely upon. — Carl Sagan

There was danger at times that women might not be judged by the highest standards, but more leniently because of their sex. "She is a remarkably good chemist
for a woman," you might hear a man say. It seemed to me essential, if the ablest young women scholars were to achieve the best work of which they were capable, that they should be held to the most rigorous standards ... To advance, a woman must do at least as good work as her male colleagues, usually better. — Virginia Gildersleeve

The killjoys initiated automobile crash standards so rigorous that we can't buy a car that hasn't been dropped from the top of a phone pole with our whole family strapped inside. — P. J. O'Rourke

What delights us in the spring is more a sensation than an appearance, more a hope than any visible reality. There is something in the softness of the air, in the lengthening of the days, in the very sounds and odors of the sweet time, that caresses us and consoles us after the rigorous weeks of winter. — Philip Gilbert Hamerton

Therapy, therapists, promised a rigorous lack of judgment (but wasn't that an impossibility, to talk to a person and not be judged?), and yet behind every question was a nudge, one that pushed you gently but inexorably toward a recognition of some flaw, toward solving a problem you hadn't known existed. — Hanya Yanagihara

The Cloud of Unknowing was written by someone who was exceedingly tough-minded in the sense in which William James used the phrase. He was most unsentimental, matter of fact, and down to earth; and he regarded this habit of mind as a prerequisite for the work in which he was engaged. He proceeded upon the belief that when an individual undertakes to bring his life into relation to God, he is embarking upon a serious and demanding task, a task that leaves no leeway for self-deception or illusion. It requires the most rigorous dedication and self-knowledge. The Cloud of Unknowing is therefore a book of strong and earnest thinking. It makes a realistic appraisal of the problems and weaknesses of individual human beings, for it regards man's imperfections as the raw material to be worked with in carrying out the discipline of spiritual development. — Ira Progoff

Hangover cure: Rigorous sex, hydration, hot bath, then "go up for half an hour in an open aeroplane. (needless to say, with a non-hungover person at the controls)." — Kingsley Amis

Every day, the New York Times carries a motto in a box on its front page. "All the News That's Fit to Print," it says. It's been saying it for decades, day in and day out. I imagine most readers of the canonical sheet have long ceased to notice this bannered and flaunted symbol of its mental furniture. I myself check every day to make sure that the bright, smug, pompous, idiotic claim is still there. Then I check to make sure that it still irritates me. If I can still exclaim, under my breath, why do they insult me and what do they take me for and what the hell is it supposed to mean unless it's as obviously complacent and conceited and censorious as it seems to be, then at least I know I still have a pulse. You may wish to choose a more rigorous mental workout but I credit this daily infusion of annoyance with extending my lifespan. — Christopher Hitchens

Well into the 19th century there were pronouncements from just about every branch of science and medicine that reading, writing, and thinking were dangerous for women. Articles in the Lancet declared that women's brains would burst and their uteruses atrophy if they engaged in any form of rigorous thinking. The famous physician J.D. Kellogg insisted that novel reading was the greatest cause of uterine disease among young women and urged parents to protect their daughters from the dreaded consequences of print. — Dale Spender

The completion of a rigorous course in mathematics - it is not even necessary that the student does well in such a course - appears to be an excellent means of sharpening the mind and developing mental skills that are of general benefit. — Keith Devlin

What the Ellison Foundation and I are hoping to encourage is a more holistic approach to psychiatry, in which psychotherapy is put on as rigorous a level as psychopharmacology. — Eric Kandel

Prescription of the correct cure is dependent on a rigorous analysis of the reality. — Ngugi Wa Thiong'o

In constructing the Coast Guard, Hamilton insisted on rigorous professionalism and irreproachable conduct. He knew that if revenue-cutter captains searched vessels in an overbearing fashion, this high-handed behavior might sap public support, so he urged firmness tempered with restraint. He reminded skippers to "always keep in mind that their countrymen are free men and as such are impatient of everything that bears the least mark of a domineering spirit. [You] will therefore refrain . . . from whatever has the semblance of haughtiness, rudeness, or insult." 34 So masterly was Hamilton's directive about boarding foreign vessels that it was still being applied during the 1962 Cuban missile crisis. Hamilton — Ron Chernow

At times God's best pupils experience the most rigorous and continuous courses. Eventually those who prove to be men of Christ will thereby become distinguished alumni of life's school of affliction, graduating with honors. — Neal A. Maxwell

Thus, in a sense, mathematics has been most advanced by those who distinguished themselves by intuition rather than by rigorous proofs. — Felix Klein

All of us who desire the kingdom of God are, by the Lord's decree, under an equal and rigorous necessity of seeking after the grace of Baptism. — Saint Basil

If "socialism" is defined as "ownership of the means of production"
and this is both the orthodox and the only rigorous definition
then the United States is the first truly Socialist country. — Peter Drucker

There is in the soul a desire for not thinking.
For being still. Coupled with this
a desire to be strict, yes, and rigorous.
But the soul is also a smooth son of a bitch,
not always trustworthy. And I forgot that. — Raymond Carver

Now, come over here so I can pat you down."
"But you don't have-" Percy stopped. "Uh, sure."
He stood next to the armless statue. Terminus conducted a rigorous mental pat down.
"You seem to be clean," Terminus decided. "Do you have anything to declare?"
"Yes," Percy said. "I declare that this is stupid. — Rick Riordan

All an investor can do is follow a consistently disciplined and rigorous approach; over time the returns will come — Seth Klarman

In subjective terms, the search for the self seems to entail a paradox:we are, after all, looking for the very thing that is doing the looking. Thousands of years of human experience suggests, however, that the paradox here is only apparent: it is not merely that the component of our experience that we call "I" cannot be found; it is that it actually disappears when looked for in a rigorous way. — Sam Harris

I think there are different ways of being rigorous, and I am asking people to be as rigorous in their pleasure as in their criticism. — Barbara Kruger

Unfortunately, parents who put a priority on saving kids from frustration and teachers who put a priority on challenging their students often butt heads, and consequently, the parent-teacher partnership has reached a breaking point. Teaching has become a push and pull between opposing forces in which parents want teachers to educate their children with increasing rigor, but reject those rigorous lessons as "too hard" or "too frustrating" for their children to endure. Parents rightly feel protective of their children's self-esteem, but teachers too often bear the brunt of parental ire. — Jessica Lahey

NSF is the only federal agency with a proven track record of selecting education projects through a rigorous, careful and competitive process that draws on a wide variety of experts from outside government. — Bob Inglis

In the visual arts, for example, the semiological approach to graphics provides a rigorous analysis of the visual means used by the artist. It defines the basic properties and laws governing the arts and suggests objective criteria for art criticism. — Jacques Bertin

Truth takes the stamp of the souls it enters. It is rigorous and rough in arid souls, but tempers and softens itself in loving natures. — Joseph Joubert

Descriptive geometry has two objects: the first is to establish methods to represent on drawing paper which has only two dimensions,-namely, length and width,-all solids of nature which have three dimensions,-length, width, and depth,-provided, however, that these solids are capable of rigorous definition.
The second object is to furnish means to recognize accordingly an exact description of the forms of solids and to derive thereby all truths which result from their forms and their respective positions. — Gaspard Monge

the simplicity of many of Bush's pronouncements is often misinterpreted as evidence that he has penetrated to the core of a complex issue, when in fact exactly the opposite is true: They often mark his refusal even to consider complexity. And that's particularly troubling in a world where the challenges America faces are often quite complex and require rigorous, sustained, disciplined analysis. — Al Gore

When I visit a new bookstore, I demand cleanliness, computer monitors, and rigorous alphabetization. When I visit a secondhand bookstore, I prefer indifferent housekeeping, sleeping cats, and sufficient organizational chaos ... — Anne Fadiman

'Bonnie and Clyde' was the first show and the first role that I got to originate. Being part of that from the ground up and investing three years of my life into seeing that show come to Broadway was really rigorous but also so exciting. — Laura Osnes

I was not a happy runner. I did it to stay interested in my body, to stay informed, and to set up clear lines of endeavor, a standard to meet, a limit to stay within. I was just enough of a puritan to think there must be some virtue in rigorous things, although I was careful not to overdo it. I never wore the clothes. the shorts, tank top, high socks. Just running shoes and a lightweight shirt and jeans. I ran disguised as an ordinary person. — Don DeLillo

To make music means to express human intelligence by sonic means. This is intelligence in its broadest sense, which includes not only the peregrinations of pure logic but also the "logic" of emotions and intuition. My musical techniques, although often rigorous in their internal structure, leave many openings through which the most complex and mysterious factors of the intelligence may penetrate. — Iannis Xenakis

He has fantastic powers. He can be imperious, abrupt, impatient with sloppy procedures, but he is also poetic, visionary, romantic. He is possessed by two geniuses: dry-eyed, rigorous exactitude, and generous leaps of imagination - non-rigid, non-uniform and innovative. — Warren Winiarski

I won't say that writing tamed the Black Beast. It soothed him, though, enough so he agreed simply to occupy a corner of my mind ... Gradually, I redirected my focus and skills towards causes much closer to my own heart: writing and mental health advocacy.
[ ... ]
I felt so good at times that I even wondered, was I still bipolar? In my community work, I saw so many people who were much worse off than I was - deep in their disease in a way I no longer seemed to be. I knew that this often happens to manic-depressives: the brain forgets the ravages of the illness they way a woman forgets the pains of childbirth. You have to, to survive. But it's always a dangerous place to be, because you inevitably start to question the need for medication, therapy, and all the other rigorous stopgaps of sanity so carefully put into place to prevent another episode. — Terri Cheney

We have a remarkable instance and evidence of the happy and great influence of such a strong rod as has been described to promote the universal prosperity of a people in the history of the reign of Solomon, though many of the people were uneasy under his government, and thought him too rigorous in his administration (see 1 Kings xii. 4). "Judah and Israel dwelt safely, every man under his vine and under his fig-tree, from Dan even to Beersheba, all the days of Solomon," 1 Kings iv. 25. "And he made silver to be among them as stones for abundance," chap x. 27. — Jonathan Edwards

Every design is a rigorous attempt to capture a concrete moment of a transitory image in all its nuances. The extent to which this transitory quality is captured, is reflected in the designs: the more precise they are, the more vulnerable. — Alvaro Siza Vieira

Music, to me, was - is - representative of everything I like most in life. It's beautiful and fun, but very rigorous. If you wanted to be good you had to work like crazy. It was a real relationship between effort and reward. My musical life experiences were just as important to me, in terms of forming my development, as my political experiences or my academic life. — William J. Clinton

Education (the institution) has now adopted values, attitudes, and practices that make any rigorous understanding of the human self and life impossible. — Dallas Willard

Sometimes magnificent visual art takes root in the humblest of soils. Advertisements painted on old barns, tattoos, fruit crate labels, hot rod embellishments - all these media and many other non-galleried forms have hosted and fostered esthetic delights that satisfy any rigorous definition of art. — Paul Di Filippo

no master could be isolated from the dehumanizing effects of the rigorous discipline of the slave regime or from the disruptive intrusions of the market economy upon which that regime thrived. These central features of slavery, punishment and profit, destroyed for most slaveholders whatever remained of the elemental principle of the paternalist ethos: that masters were obliged to look to the needs of the slaves in return for the diligence and fidelity of the bondsmen. — James Oakes

The yeshiva where I studied considers itself modern Orthodox, not ultra-Orthodox. We followed a rigorous secular curriculum alongside traditional Talmud and Bible study. — Noah Feldman

As in the experimental sciences, truth cannot be distinguished from error as long as firm principles have not been established through the rigorous observation of facts. — Louis Pasteur

In the Far East, it is taken for granted that the training of a monk is physically rigorous and academically challenging. — Frederick Lenz

Whereas easy appeals to mystery prematurely shut off reflection about God, rigorous and earnest effort to understand him is richly rewarded with deeper appreciation of who he is, more confidence in his reality and care, and a more intelligent and profound worship of his person. — William Lane Craig

Recall Part 3c's mention of how Cantor took what had been regarded as a paradoxical, totally unhandlable feature of (Infinity)-namely that an infinite set/class/aggregate can be put into a one-to-one correspondence with its own subset-and transformed it into the technical def. of infinite set. Watch how he does the same thing here, turning what appear to be devastating objections into rigorous criteria, by defining a set S as any aggregate of collection of discrete entities that satisfies two conditions: (1) S can be entertained by the mind as an aggregate, and (2) There is some stated rule or condition via which one can determine, for any entity x, whether or not x is a member of S. — David Foster Wallace

A book isn't rigorous if students aren't reading it. — Penny Kittle

I find great satisfaction in the rigorous structure of the grid, but I like the organic on the grid so that there's a combination of structure and chaos. — Michelle Stuart

When I released my first record, I was really in the middle of having made the decision to follow the clinical psychology path, which is competitive, rigorous, and fairly conservative. — Autre Ne Veut

He had a better mind and a more rigorous temperament than me; he thought logically, and then acted on the conclusion of logical thought. Whereas most of us, I suspect, do the opposite: we make an instinctive decision, then build up an infrastructure of reasoning to justify it. And call the result common sense. — Julian Barnes

Progress in manufacturing is measured by the production of high quality goods. The unit of progress for Lean Startups is validated learning-a rigorous method for demonstrating progress when one is embedded in the soil of extreme uncertainty. — Eric Ries

IMPORTANT Book reading is a solitary and sedentary pursuit, and those who do are cautioned that a book should be used as an integral part of a well-rounded life, including a daily regimen of rigorous physical exercise, rewarding personal relationships, and sensible low-fat diet. A book should not be used a as a substitute or an excuse. — Garrison Keillor

I write narrative nonfiction, creating lively scenes through action and the use of quotes from firsthand accounts, all based on rigorous research. If I say a character leaned against a fence on a windy day, than I have at least two sources to back up these details. — Jim Murphy

The Bolsheviks could not have retained power for two and a half months, let alone two and a half years, without the most rigorous and truly iron discipline in our Party. — Vladimir Lenin

What is the most rigorous law of our being? Growth. — Mark Twain

A home life where it's so full of so many rigorous ideas about the way things should be, this word "should," I think is absolutely toxic to children. It hurts their personalities, it hurts their points of view in the world, it hurts their ability to be open and caring and curious. An element of allowance in a family, is, I think, really a positive thing. — Mark Ruffalo

It remains an astonishing, disturbing fact that in America - a nation where nearly every new drug is subjected to rigorous scrutiny as a potential carcinogen, and even the bare hint of a substance's link to cancer ignites a firestorm of public hysteria and media anxiety - one of the most potent and common carcinogens known to humans can be freely bought and sold at every corner store for a few dollars. — Siddhartha Mukherjee

Faith does not cease being active as it undertakes the process of rigorous thinking. One need not disavow the gifts of intellect in giving thought to their Giver — Thomas C. Oden

Rigorous authority and justice are the kindness of kings. — Napoleon Bonaparte

From the perspective of the radicals, the habitus basis of human existence is, as a whole, no more than a spiritually worthless puppet theatre into which a free ego-soul must be implanted after the fact, and through the greatest effort. If this fails, one experiences an effect in most people that is familiar from many athletes and models: they make a promising visual impression - but if one knocks, no one is at home. According to these doctrines, the adept can only rid themselves of their baggage by subjecting their life to a rigorous practice regime by which they can de-automize their behaviour in all important dimensions. At the same time, they must re-automatize their newly acquired behaviour so that what they want to be or represent becomes second nature. — Peter Sloterdijk

My music is very, very precise. It's very rigorous. The forms are much more intricate than you would imagine. — Meredith Monk

At the very best, a mind enclosed in language is in prison. It is limited to the number of relations which words can make simultaneously present to it; and remains in ignorance of thoughts which involve the combination of a greater number. These thoughts are outside language, they are unformulable, although they are perfectly rigorous and clear and although every one of the relations they involve is capable of precise expression in words. So the mind moves in a closed space of partial truth, which may be larger or smaller, without ever being able so much as to glance at what is outside. — Simone Weil

At one time in my infancy I also knew no Latin, and yet by listening I learnt it with no fear or pain at all, from my nurses caressing me, from people laughing over jokes, and from those who played games and were enjoying them. I learnt Latin without the threat of punishment from anyone forcing me to learn it. My own heart constrained me to bring its concepts to birth, which I could not have done unless I had learnt some words, not from formal teaching but by listening to people talking; and they in turn were the audience for my thoughts. This experience sufficiently illuminates the truth that free curiosity has greater power to stimulate learning than rigorous coercion. — Augustine Of Hippo

Banish professionalism from our midst, Oh God, an din its place put passionate prayer, poverty of spirit, hunger for God, rigorous study of holy things, white-hot devotion to Jesus Christ, utter indifference to all material gain, and unremitting labor to rescue the perishing, perfect the saints, and glorify our sovreign Lord.
Humble us, O God, under your mighty hand, and let us rise, not as professionals, but as witnesses and partakers of the sufferings of Christ. — John Piper

Faith in the possibilities of continued and rigorous inquiry does not limit access to truth to any channel or scheme of things. It does not first say that truth is universal and then add there is but one road to it. — John Dewey

The foundations of population genetics were laid chiefly by mathematical deduction from basic premises contained in the works of Mendel and Morgan and their followers. Haldane, Wright, and Fisher are the pioneers of population genetics whose main research equipment was paper and ink rather than microscopes, experimental fields, Drosophila bottles, or mouse cages. Theirs is theoretical biology at its best, and it has provided a guiding light for rigorous quantitative experimentation and observation. — Theodosius Dobzhansky

Science isn't done by consensus. It's done by rigorous testing. — Orson Scott Card

And so far, their most recent results had been perfect. Their meetings in Germany and Switzerland had gone brilliantly. The testing done in their laboratories there was even more rigorous than what had been done in the States. They were sure now. It was safe. They could move ahead to Phase One Human Trials, as soon as the FDA approved it, which meant giving low doses of the medication to a select number of willing, well-informed subjects, and seeing how they fared. — Danielle Steel

Allowing children to learn about what interests them is good, but helping them do it in a meaningful, rigorous way is better. Freedom and choice are good, but a life steeped in thinking, learning, and doing is better. It's not enough to say, "Go, do whatever you like." To help children become skilled thinkers and learners, to help them become people who make and do, we need a life centered around those experiences. We need to show them how to accomplish the things they want to do. We need to prepare them to make the life they want. — Lori McWilliam Pickert

I'm a great believer in chaos. I don't believe that you start with a formula and then you fulfill the formula. Chaos is a much better instigator, because we live in chaos - we don't live in a rigorous form. — Sam Shepard

One of the principal obstacles to the rapid diffusion of a new idea lies in the difficulty of finding suitable expression to convey its essential point to other minds. Words may have to be strained into a new sense, and scientific controversies constantly resolve themselves into differences about the meaning of words. On the other hand, a happy nomenclature has sometimes been more powerful than rigorous logic in allowing a new train of thought to be quickly and generally accepted. — Arthur Schuster

As a reward of their clean living and good habits these great stars have been able to withstand the rigorous test of stamina and physical exertion and have thus successfully extended their most remarkable careers over a period of many strenuous years. — Major Taylor

What's to rationalize? You mean you shouldn't pray if you haven't got your s
t together? This is another fairly common misconception of faith, which is that people who go to church, or people who pray, or people who talk about their religion must be, somehow more pious or ethically rigorous or have more morally cleansed lifestyle. The high correlation is supposed to be between faith and your search, the depth of your search, your willingness to try, your willingness to admit error, your hope and belief in the ultimate meaning and value of that search.' - Timothy Shriver — J. Randy Taraborrelli

When grace is given it comes to us as joy, maybe, but it can also be earned, I am convinced, through the rigorous examination of the sources of pain. — May Sarton

I believe that the demand for long-form quality journalism is strong and I think that despite all of the changes in technology over the past few years, people still want in-depth, rigorous reporting. — Chris Hughes
