Top Knowledge Applied Quotes

Knowledge Applied Quotes By Sunday Adelaja

Wisdom is knowledge correctly applied. Therefore you should gain knowledge! — Sunday Adelaja

Knowledge Applied Quotes By Roshan Sharma

All the world talks, knowledge or information, takes you nowhere unless it's applied into life. It's only the experience, which allows you to see, beyond the present state. — Roshan Sharma

Knowledge Applied Quotes By Gichin Funakoshi

Once a kata has been learned, it must be practised repeatedly until it can be applied in an emergency, for knowledge of just the sequence of a kata in karate is useless. — Gichin Funakoshi

Knowledge Applied Quotes By Robert Andrews Millikan

One of the chief inhibitions to human progress arises because of the extreme slowness with which the advances in knowledge become translated into action for the benefit of society as a whole. There is no step more important for the removal of that inhibition than that of providing for intimate contact between the leaders in the fields of pure and applied science. — Robert Andrews Millikan

Knowledge Applied Quotes By William Whewell

In order that the facts obtained by observation and experiment may be capable of being used in furtherance of our exact and solid knowledge, they must be apprehended and analysed according to some Conceptions which, applied for this purpose, give distinct and definite results, such as can be steadily taken hold of and reasoned from. — William Whewell

Knowledge Applied Quotes By Isaac Asimov

Excellence, he is known as the Mule. He is spoken of little, in a factual sense, but I have gathered the scraps and fragments of knowledge and winnowed out the most probable of them. He is apparently a man of neither birth nor standing. His father, unknown. His mother, dead in childbirth. His upbringing, that of a vagabond. His education, that of the tramp worlds, and the backwash alleys of space. He has no name other than that of the Mule, a name reportedly applied by himself to himself, and signifying, by popular explanation, his immense physical strength, and stubbornness of purpose. — Isaac Asimov

Knowledge Applied Quotes By Jack Kornfield

A bulging portfolio of spiritual experiences matters little if it does not have the power to sustain us through the inevitable moments of grief, loss, and change. Knowledge and achievements matter little if we do not yet know how to touch the heart of another and be touched. Wisdom is alive only as long as it is lived, understanding is liberating only as long as it is applied. — Jack Kornfield

Knowledge Applied Quotes By John Dewey

The notion that "applied" knowledge is somehow less worthy than "pure" knowledge, was natural to a society in which all useful work was performed by slaves and serfs, and in which industry was controlled by the models set by custom rather than by intelligence. Science, or the highest knowing, was then identified with pure theorizing, apart from all application in the uses of life; and knowledge relating to useful arts suffered the stigma attaching to the classes who engaged in them. — John Dewey

Knowledge Applied Quotes By Lewis Wolpert

Reliable scientific knowledge is value free and has no moral or ethical value. Science tells us how the world is ... Dangers and ethical issue arise only when science is applied as technology. — Lewis Wolpert

Knowledge Applied Quotes By Avicenna

The theory of medicine, therefore, presents what is useful in thought, but does not indicate how it is to be applied in practice-the mode of operation of these principles. The theory, when mastered, gives us a certain kind of knowledge. Thus we say, for example, there are three forms of fevers and nine constitutions. The practice of medicine is not the work which the physician carries out, but is that branch of medical knowledge which, when acquired, enables one to form an opinion upon which to base the proper plan of treatment. — Avicenna

Knowledge Applied Quotes By Peter Drucker

Knowledge is the source of Wealth. Applied to tasks we already know, it becomes Productivity. Applied to tasks that are new, it becomes Innovation ... — Peter Drucker

Knowledge Applied Quotes By Robin S. Sharma

Knowledge is only potential power. For the power to be manifested, it must be applied. Most people know what they should do in any given situation, or in their lives, for that matter. The problem is that they don't take daily, consistent action to apply the knowledge and realize their dreams. — Robin S. Sharma

Knowledge Applied Quotes By Anonymous

The adult Feynman asked: If all scientific knowledge were lost in a cataclysm, what single statement would preserve the most information for the next generations of creatures? How could we best pass on our understanding of the world? He proposed, "All things are made of atoms - little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another," and he added, "In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied. — Anonymous

Knowledge Applied Quotes By Dada Bhagwan

Knowledge of all living beings of the entire world is in only one Soul. But the knowledge that sees the ego and everything, as objects to be known (gneya); only that knowledge is called as the 'Knowledge'. However, that is partial Knowledge but only from that moment it is regarded as real applied focused awareness. Where there is Knowledge, the focused applied awareness may be partial or complete. — Dada Bhagwan

Knowledge Applied Quotes By Martin R. Lemieux

Self awareness is only powerful when knowledge is understood and applied, only then can it manifest into true wisdom! — Martin R. Lemieux

Knowledge Applied Quotes By Thomas Lewis

Science is an inherent contradiction - systematic wonder - applied to the natural world. In its mundane form, the methodical instinct prevails and the result, an orderly procession of papers, advances the perimeter of knowledge, step by laborious step. Great scientific minds partake of that daily discipline and can also suspend it, yielding to the sheer love of allowing the mental engine to spin free. And then Einstein imagines himself riding a light beam, Kekule formulates the structure of benzene in a dream, and Fleming's eye travels past the annoying mold on his glassware to the clear ring surrounding it - a lucid halo in a dish otherwise opaque with bacteria - and penicillin is born. Who knows how many scientific revolutions have been missed because their potential inaugurators disregarded the whimsical, the incidental, the inconvenient inside the laboratory? — Thomas Lewis

Knowledge Applied Quotes By Francis Bacon

The registering of doubts hath two excellent uses: the one, that it saveth philosophy from errors and falsehoods; when that which is not fully appearing is not collected into assertion, whereby error might draw error, but reserved in doubt: the other, that the entry of doubts are as so many
suckers or sponges to draw use of knowledge; insomuch as that which, if doubts had not preceded, a man should never have advised, but passed it over without note, by the suggestion and solicitation of doubts, is made to be attended and applied. — Francis Bacon

Knowledge Applied Quotes By John Crowley

Serenity. Now you could wish for that, naming no conditions: a permanent inner vacation, escape made good. To somehow have this motionlessness that he drew in with the sweet air he inhaled for his inward weather always.
But there were problems too with wishing for moral qualities, serenity, large-mindedness. The interdiction (which Pierce thought obvious) against wishing for such things as artistic abilities
sit down at the piano, the Appassionata flows suddenly from your fingertips
applied in a way to wisdom too, to enlightenment, to heart-knowledge, useless unless earned, the earning of it being no doubt all that it consisted of. — John Crowley

Knowledge Applied Quotes By Max Heindel

We venture to make the assertion that there is but one sin: IGNORANCE, and but one salvation: APPLIED KNOWLEDGE. — Max Heindel

Knowledge Applied Quotes By Hyrum W. Smith

Wisdom: Knowledge rightly applied. We assimilate lots of knowledge. Whether or not we do anything with that knowledge is a measure of our wisdom. That implies some change ... and change can be difficult. — Hyrum W. Smith

Knowledge Applied Quotes By Michael Faraday

If the term education may be understood in so large a sense as to include all that belongs to the improvement of the mind, either by the acquisition of the knowledge of others or by increase of it through its own exertions, we learn by them what is the kind of education science offers to man. It teaches us to be neglectful of nothing - not to despise the small beginnings, for they precede of necessity all great things in the knowledge of science, either pure or applied. — Michael Faraday

Knowledge Applied Quotes By David B. Haight

Knowing that we should love is not enough. But when knowledge is applied through service, love can secure for us the blessings of heaven. — David B. Haight

Knowledge Applied Quotes By Russell Shorto

They had applied their doubts to the very head that had introduced doubt as a tool for advancing knowledge. And in the end they gave the head a nod. — Russell Shorto

Knowledge Applied Quotes By Richard Saul Wurman

The most common definition of [the word information] is: the action of informing; formation or molding of the mind or character, training, instruction, teaching; communication of instructive knowledge.
This definition remained fairly constant until the years immediately following World War II, when it came in vogue to use 'information' as a technological term to define anything that was sent over an electric or mechanical channel. 'Information' became part of the vocabulary of the science of messages. And, suddenly, the appellation could be applied to something that didn't necessarily have to inform. This definition was extrapolated to general usage as something told or communicated, whether or not it made sense to the receiver. Now, the freedom engendered by such an amorphous definition has, as you might expect, encouraged its liberal deployment. It has become the single most important word of our decade, the suspense of our lives and our work. — Richard Saul Wurman

Knowledge Applied Quotes By Wan Mohd Nor Wan Daud

In a proper Islamic University, fard 'ain knowledge which represents the permanent intellectual and spiritual needs of the human soul
should form the core curriculum, and should be made obligatory to all students. Fard kifayah knowledge
reflecting societal needs and global trends
is not obligatory to all, but must be mastered by and adequate number of Muslims to ensure the proper development of the Community and to safeguard its proper place in world affairs. The fard 'ain knowledge shall include knowledge of the traditional Islamic sciences such as the Arabic language, metaphysics, the Qur'an and Hadith, ethics, the shari'ah sciences, and the history of Islam. Consonant with our position that these fard 'ain sciences are not static but dynamic, they should be continuously studied, analyzed, and applied in relation to the fard kifayah sciences; i.e. the fields of their specialization. — Wan Mohd Nor Wan Daud

Knowledge Applied Quotes By Carl Jung

It is in applied psychology, if anywhere, that today we should be modest and grant validity to a number of apparently contradictory opinions; for we are still far from having anything like a thorough knowledge of the human psyche, that most challenging field of scientific enquiry. For the present we have merely more or less plausible opinions that defy reconciliation. — Carl Jung

Knowledge Applied Quotes By Barbara Paterson

I believe that teaching is a creative art in which evidence based knowledge is applied toward meeting the learning goals of learners. I believe that effective teaching is often the spark that ignites the imagination, possibility, and promise for learners, including the teacher. — Barbara Paterson

Knowledge Applied Quotes By Jane Borodale

Nothing good was learnt too swiftly. Knowledge should be a purposeful accumulance of observed experience, applied and tested to the full. — Jane Borodale

Knowledge Applied Quotes By Joseph Smith Jr.

The exaltation and happiness of any community, goes hand in hand with the knowledge possessed by the people, when applied to laudable ends; whereupon we can exclaim like the wise man; righteousness exalteth a nation; for righteousness embraces knowledge and knowledge is power. — Joseph Smith Jr.

Knowledge Applied Quotes By Ray Kurzweil

We have the means right now to live long enough to live forever. Existing knowledge can be aggressively applied to dramatically slow down aging processes so we can still be in vital health when the more radical life extending therapies from biotechnology and nanotechnology become available. But most baby boomers won't make it because they are unaware of the accelerating aging process in their bodies and the opportunity to intervene. — Ray Kurzweil

Knowledge Applied Quotes By Michael Polanyi

While tacit knowledge can be possessed by itself, explicit knowledge must rely on being tacitly understood and applied. Hence all knowledge is either tacit or rooted in tacit knowledge. A wholly explicit knowledge is unthinkable. — Michael Polanyi

Knowledge Applied Quotes By R. Alan Woods

Dynamic/Active vs. Static/Passive. The Biblical statement, '...and with knowledge gain understanding, and with understanding gain wisdom'- NT (passim), speaks to an active experiential involvement necessary on our part in producing a state of dynamic pragmatism. To my understanding, wisdom is knowledge understood and applied in our daily lives where the-rubber-meets-the-road".

~R. Alan Woods [2013] — R. Alan Woods

Knowledge Applied Quotes By John Boyd Orr

Knowledge acquired in biological research is seldom directly applicable to human beings ... The results of scientific research, obtained under these conditions, cannot be applied directly to human beings who vary widely in their hereditary make-up, in their environment, and in their past health record. — John Boyd Orr

Knowledge Applied Quotes By Ellen Swallow Richards

For this knowledge of right living, we have sought a new name ... As theology is the science of religious life, and biology the science of [physical] life ... so let Oekology be henceforth the science of [our] normal lives ... the worthiest of all the applied sciences which teaches the principles on which to found ... healthy ... and happy life. — Ellen Swallow Richards

Knowledge Applied Quotes By Dada Bhagwan

Gnan (knowledge of the Self) can never become agnan (knowledge other than the self, of relative world). It is called agnan only when the focused applied awareness of the Self changes. — Dada Bhagwan

Knowledge Applied Quotes By William Shockley

Frequently, I have been asked if an experiment I have planned is pure or applied science; to me it is more important to know if the experiment will yield new and probably enduring knowledge about nature. If it is likely to yield such knowledge, it is, in my opinion, good fundamental research; and this is more important than whether the motivation is purely aesthetic satisfaction on the part of the experimenter on the one hand or the improvement of the stability of a high-power transistor on the other. — William Shockley

Knowledge Applied Quotes By Jermaine Jackson

Michael applied himself better than I did at school. His thirst for knowledge was far greater than any of the rest of us. He was that curious kid who asked, 'Why? Why? Why?' and he listened to and logged every detail. I'm sure his head had an in-built recording chip for data, facts, figures, lyrics and dance moves. — Jermaine Jackson

Knowledge Applied Quotes By F Scott Fitzgerald

McKisco's contacts with the princely classes in America had impressed upon him their uncertain and fumbling snobbery, their delight in ignorance and their deliberate rudeness, all lifted from the English with no regard paid to factors that make English philistinism and rudeness purposeful, and applied in a land where a little knowledge and civility buy more than they do anywhere else - an attitude which reached its apogee in the "Harvard manner" of about 1900. — F Scott Fitzgerald

Knowledge Applied Quotes By Greg Graffin

Bad Religion took a long time to develop into gold-record-status artists. Along the way we learned and applied our knowledge, and Atlantic helped us every step of the way, since 1993. — Greg Graffin

Knowledge Applied Quotes By Andy Andrews

Circumstances do not push or pull. They are daily lessons to be studied and gleaned for new knowledge and wisdom. Knowledge and wisdom that is applied will bring about a brighter tomorrow. A person who is depressed is spending too much time thinking about the way things are now and not enough time thinking about how he wants things to be. — Andy Andrews

Knowledge Applied Quotes By Robert G. Ingersoll

Our civilization is not Christian. It does not come from the skies. It is not a result of "inspiration." It is the child of invention, of discovery, of applied knowledge
that is to say, of science. When man becomes great and grand enough to admit that all have equal rights; when thought is untrammeled; when worship shall consist in doing useful things; when religion means the discharge of obligations to our fellow-men, then, and not until then, will the world be civilized. — Robert G. Ingersoll

Knowledge Applied Quotes By Radhe Maa

Spiritual knowledge is fruitful only when it is applied — Radhe Maa

Knowledge Applied Quotes By Isaac Asimov

One might suppose that reality must be held to at all costs. However, though that may be the moral thing to do, it is not necessarily the most useful thing to do. The Greeks themselves chose the ideal over the real in their geometry and demonstrated very well that far more could be achieved by consideration of abstract line and form than by a study of the real lines and forms of the world; the greater understanding achieved through abstraction could be applied most usefully to the very reality that was ignored in the process of gaining knowledge. — Isaac Asimov

Knowledge Applied Quotes By Josh Kaufman

Business is essentially applied rationality:
a systematic process of thinking that produces a real-world result. Instead of mortgaging your life to go to business school, it's possible to dramatically increase your knowledge of business on your own time and with little cost - without setting foot inside a classroom. — Josh Kaufman

Knowledge Applied Quotes By Haile Selassie

Knowledge is power. If it is not applied properly to create, let there be no doubts, it will destroy. — Haile Selassie

Knowledge Applied Quotes By Alexander The Great

Without Knowledge, Skill cannot be focused. Without Skill, Strength cannot be brought to bear and without Strength, Knowledge may not be applied. — Alexander The Great

Knowledge Applied Quotes By Cicely Hamilton

If and when our civilization comes to ruin, the destructive agent will be Science; man's knowledge of science, applied to warfare, meaning slaughter not only of human bodies, but of human institutions, of all we have created through the centuries. — Cicely Hamilton

Knowledge Applied Quotes By Wolfgang Pauli

Modern man, seeking a middle position in the evaluation of sense impression and thought, can, following Plato , interpret the process of understanding nature as a correspondence, that is, a coming into congruence of pre-existing images of the human psyche with external objects and their behaviour. Modern man, of course, unlike Plato , looks on the pre-existent original images also as not invariable, but as relative to the development of a conscious point of view, so that the word "dialectic" which Plato is fond of using may be applied to the process of development of human knowledge. — Wolfgang Pauli

Knowledge Applied Quotes By Beth Moore

Wisdom is knowledge applied. Head knowledge is useless on the battlefield. Knowledge stamped on the heartmmakes one wise — Beth Moore

Knowledge Applied Quotes By Thomas D

If you want success badly enough, you must weigh each thought, action, and experience. The reward you reap will be the knowledge of some of history's best kept secret, which when understood and applied will truly guide you to the success in life that all have dreamed about, but only few have attained — Thomas D

Knowledge Applied Quotes By Dada Bhagwan

Complete focused applied awareness of the Soul (shuddha upayog) is considered absolute Knowledge (keval gnan). — Dada Bhagwan

Knowledge Applied Quotes By Thomas Nagel

Evolutionary naturalism offers an explanation of our knowledge that is seriously inadequate, when applied to the knowledge-generating capacities that we take ourselves to have. — Thomas Nagel

Knowledge Applied Quotes By Henry Petroski

Whether or not science can be applied to that mental construct [i.e. the designed entity] is a matter of availability. If there is body of scientific knowledge that can be applied, then it would be foolish not to exploit it. However, if there is none, it does not mean that the thing cannot be designed, made, and used safely. — Henry Petroski

Knowledge Applied Quotes By Fritz Haber

The field of scientific abstraction encompasses independent kingdoms of ideas and of experiments and within these, rulers whose fame outlasts the centuries. But they are not the only kings in science. He also is a king who guides the spirit of his contemporaries by knowledge and creative work, by teaching and research in the field of applied science, and who conquers for science provinces which have only been raided by craftsmen. — Fritz Haber

Knowledge Applied Quotes By Adolf Hitler

Being daily better informed about their knowledge than my adversaries themselves, I argued till finally one day they applied the one means that wins the easiest victory over reason: terror and force. — Adolf Hitler

Knowledge Applied Quotes By Isabel Paterson

By stressing intrinsic value in thought. And it is true that when men have become engrossed in practical devices they are apt to narrow their field of vision and lose sight of the interconnection of the various branches of knowledge. More than that, as is now the case, they will even forget the larger principles they have applied, and on which their well-being depends. — Isabel Paterson

Knowledge Applied Quotes By L.E. Modesitt Jr.

Knowledge begets power. "Power begets force. "Force is applied from ignorance." With a smile of habit, I looked at the blond youth on the end. "Sergol? Would you finish it?" "Knowledge leads to ignorance. — L.E. Modesitt Jr.

Knowledge Applied Quotes By Ayn Rand

For my purpose, the non-fiction form of abstract knowledge doesn't interest me; the final, applied form of fiction, of story, does. — Ayn Rand

Knowledge Applied Quotes By Thomas Lewis

People rely on intelligence to solve problems, and they are naturally baffled when comprehension proves impotent to effect emotional change. To the neocortical brain, rich in the power of abstractions, understanding makes all the difference, but it doesn't count for much in the neural systems that evolved before understanding existed. Ideas bounce like so many peas off the sturdy incomprehension of the limbic and reptilian brains. The dogged implicitness of emotional knowledge, its relentless unreasoning force, prevents logic from granting salvation just as it precludes self-help books from helping. The sheer volume and variety of self-help paraphernalia testify at once to the vastness of the appetite they address and their inability to satisfy it. (118) — Thomas Lewis

Knowledge Applied Quotes By Dale Carnegie

Knowledge isn't power until it is applied. — Dale Carnegie

Knowledge Applied Quotes By Peter Drucker

Knowledge is being applied to knowledge itself. It is now fast becoming the one factor in production, sidelining both capital and labour. — Peter Drucker

Knowledge Applied Quotes By John Arbuthnot

The Reader may here observe the Force of Numbers, which can be successfully applied, even to those things, which one would imagine are subject to no Rules. There are very few things which we know, which are not capable of being reduc'd to a Mathematical Reasoning, and when they cannot, it's a sign our Knowledge of them is very small and confus'd; and where a mathematical reasoning can be had, it's as great folly to make use of any other, as to grope for a thing in the dark when you have a Candle standing by you. — John Arbuthnot

Knowledge Applied Quotes By Napoleon Hill

INSUFFICIENT EDUCATION. This is a handicap that may be overcome with comparative ease. Experience has proven that the best-educated people are often those who are known as 'self-made' or self-educated. It takes more than a university degree to make one a person of education. Any person who is educated has learned to get whatever they want in life without violating the rights of others. Education consists not so much of knowledge, but of knowledge effectively and persistently applied. People are paid not merely for what they know, but more particularly for what they do with what they know. — Napoleon Hill

Knowledge Applied Quotes By Eric Thomas

Knowledge isn't power, applied knowledge is power — Eric Thomas

Knowledge Applied Quotes By Walter M. Miller Jr.

Because a doubt is not a denial. Doubt is a powerful tool, and it should be applied to history. — Walter M. Miller Jr.

Knowledge Applied Quotes By Elizabeth Kenny

I do not want medical men to discuss whether or not my work is valuable, because I know what it will do. I want them to tell me how best this new knowledge of rapidly restoring paralysed people to health and strength can be applied where it is needed. — Elizabeth Kenny

Knowledge Applied Quotes By Marjorie Garber

We do literature a real disservice if we reduce it to knowledge or to use, to a problem to be solved. If literature solves problems, it does so by its own inexhaustibility, and by its ultimate refusal to be applied or used, even for moral good. This refusal, indeed, is literature's most moral act. At a time when meanings are manifold, disparate, and always changing, the rich possibility of interpretation
the happy resistance of the text to ever be fully known and mastered
is one of the most exhilarating products of human culture. — Marjorie Garber

Knowledge Applied Quotes By Roberto Bolano

The pain, or the memory of pain, that here was literally sucked away by something nameless until only a void was left. The knowledge that this question was possible: pain that turns finally into emptiness. The knowledge that the same equation applied to everything, more or less. — Roberto Bolano

Knowledge Applied Quotes By Idries Shah

Few things are more absurd than wise saws originally designed to inculcate or maintain the social needs of a society long past - when they are applied to today. — Idries Shah

Knowledge Applied Quotes By Richelle E. Goodrich

Knowledge gained is as useless as pride
if filed away and never applied. — Richelle E. Goodrich

Knowledge Applied Quotes By Franz Bardon

True magic therefore is the high knowledge of the more subtle powers that have not yet been acknowledged by science up to this date because the methods of scrutiny that have been applied so far do not suffice for their grasping, understanding and utilization, although the laws of magic are analogous to all official sciences of the world. — Franz Bardon

Knowledge Applied Quotes By Frank H. T. Rhodes

Knowledge humanely applied makes human progress possible. — Frank H. T. Rhodes

Knowledge Applied Quotes By Dalai Lama

Study and practice are both very important, but they must go hand in hand. Faith without knowledge is not sufficient. Faith needs to be supported by reason. However intellectual understanding that is not applied in practice is also of little use. Whatever we learn from study we need to apply sincerely in our daily lives. — Dalai Lama

Knowledge Applied Quotes By Warren Bennis

The primary goal of management education was, as originally conceived, to impart knowledge that could be applied to a variety of real-world business situations. — Warren Bennis

Knowledge Applied Quotes By Yehudi Menuhin

We embark unhesitatingly on the path, in a direction that is absolutely right and urgent, supported by everyone, in the knowledge that this path is but a learning process ... We have to keep on learning, creating, applying, by-passing, touching upon, refining and clarifying a number of notions and details that need to be improvised and applied and which, thank God, we cannot foresee. The only rigidity lies in our will, our conviction that we are on the right road and that our initiatives are most pressing. — Yehudi Menuhin

Knowledge Applied Quotes By Peter Drucker

Knowledge applied is productivity. — Peter Drucker

Knowledge Applied Quotes By Joaquin Fuster

The first proponent of cortical memory networks on a major scale was neither a neuroscientist nor a computer scientist but .. a Viennes economist: Friedrich von Hayek (1899-1992). A man of exceptionally broad knowledge and profound insight into the operation of complex systems, Hayek applied such insight with remarkable success to economics (Nobel Prize, 1974), sociology, political science, jurisprudence, evolutionary theory, psychology, and brain science (Hayek, 1952). — Joaquin Fuster

Knowledge Applied Quotes By Balfour Stewart

I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics. — Balfour Stewart
