Louis Agassiz Quotes & Sayings

Select such subjects that your pupils cannot walk out without seeing them. Train your pupils to be observers, and have them provided with the specimens about which you speak. If you can find nothing better, take a house-fly or a cricket, and let each one hold a specimen and examine it as you talk. — Louis Agassiz

I will frankly tell you that my experience in prolonged scientific investigations convinces me that a belief in God-a God who is behind and within the chaos of vanishing points of human knowledge-adds a wonderful stimulus to the man who attempts to penetrate into the regions of the unknown. — Louis Agassiz

The study of Nature is intercourse with the Highest Mind. You should never trifle with Nature. — Louis Agassiz

Embryology furnishes, also, the best measure of true affinities existing between animals. — Louis Agassiz

The facts will eventually test all our theories, and they form, after all, the only impartial jury to which we can appeal. — Louis Agassiz

The office of science is not to record possibilities; but to ascertain what nature does ... As far as Darwinism deals with mere arguments of possibilities or even probabilities, without a basis of fact, it departs from the true scientific method and injures science, as most of the devotees of the new ism have already done. — Louis Agassiz

The theory [of evolution] is a scientific mistake. — Louis Agassiz

Study nature, not books. — Louis Agassiz

As long as men inquire, they will find opportunities to know more upon these topics than those who have gone before them, so inexhaustibly rich is nature in the innermost diversity of her treasures of beauty, order and intelligence. — Louis Agassiz

I cannot afford to waste my time making money. — Louis Agassiz

America, so far as her physical history is concerned, has been falsely denominated the New World. Hers was the first dry land lifted out of the waters, hers the first shore washed by the ocean that enveloped all the earth beside; and while Europe was represented only by islands rising here and there above the sea, America already stretched an unbroken line of land from Nova Scotia to the Far West. — Louis Agassiz

A laboratory of natural history is a sanctuary where nothing profane should be tolerated. I feel less agony at improprieties in churches than in a scientific laboratory. — Louis Agassiz

The eye of the trilobite tells us that the sun shone on the old beach where he lived; for there is nothing in nature without a purpose, and when so complicated an organ was made to receive the light, there must have been light to enter it. — Louis Agassiz

The surface of the earth is not simply a stage on which the thousands of present and past inhabitants played their parts in turn. There are much more intimate relations between the earth and the living organisms which populated it, and it may even be demonstrated that the earth was developed because of them. — Louis Agassiz

The time has come when scientific truth must cease to be the property of the few, when it must be woven into the common life of the world. — Louis Agassiz

The long summer was over. For ages a tropical climate had prevailed over a great part of the earth, and animals whose home is now beneath the Equator roamed over the world from the far South to the very borders of the Arctics ... But their reign was over. A sudden intense winter, that was also to last for ages, fell upon our globe. — Louis Agassiz

But unless some great revolution in nature modifies the present relative level between land and sea, it may safely be maintained that the present outer reef is the final southern boundary of the North American continent. — Louis Agassiz

It is better to have a few forms well known than to teach a little about many hundred species. Better a dozen specimens thoroughly studied as the result of the first year's work, than to have two thousand dollars' worth of shells and corals bought from a curiosity-shop. The dozen animals would be your own. — Louis Agassiz

The resources of the Deity cannot be so meagre, that, in order to create a human being endowed with reason, he must change a monkey into a man. — Louis Agassiz

The possibilities of existence run so deeply into the extravagant that there is scarcely any conception too extraordinary for Nature to realise. — Louis Agassiz

You cannot do without one specialty. You must have some base-line to measure the work and attainments of others. For a general view of the subject, study the history of the sciences. Broad knowledge of all Nature has been the possession of no naturalist except Humboldt, and general relations constituted his specialty. — Louis Agassiz

One naturally asks, what was the use of this great engine set at work ages ago to grind, furrow, and knead over, as it were, the surface of the earth? We have our answer in the fertile soil which spreads over the temperate regions of the globe. The glacier was God's great plough. — Louis Agassiz

I sometimes hear preachers speak of the sad condition of men who live without God in the world, but a scientist who lives without God in the world seems to me worse off than ordinary men. — Louis Agassiz

Nature brings us back to absolute truth whenever we wander. — Louis Agassiz

In Europe I have been accused of taking my scientific ideas from the Church. In America I have been called a heretic, because I will not let my church-going friends pat me on the head. — Louis Agassiz

I now never make the preparations for penetrating into some small province of nature hitherto undiscovered without breathing a prayer to the Being who hides His secrets from me only to allure me graciously on to the unfolding of them. — Louis Agassiz

There is no part of the country where in the summer you cannot get a sufficient supply of the best specimens. Teach your children to bring them in for themselves. Take your text from the brooks, not from the booksellers. — Louis Agassiz

I have devoted my whole life to the study of Nature, and yet a single sentence may express all that I have done. I have shown that there is a correspondence between the succession of Fishes in geological times and the different stages of their growth in the egg,-this is all. It chanced to be a result that was found to apply to other groups and has led to other conclusions of a like nature. — Louis Agassiz

Branches or types are characterized by the plan of their structure,
Classes, by the manner in which that plan is executed, as far as ways and means are concerned,
Orders, by the degrees of complication of that structure,
Families, by their form, as far as determined by structure,
Genera, by the details of the execution in special parts, and
Species, by the relations of individuals to one another and to the world in which they live, as well as by the proportions of their parts, their ornamentation, etc. — Louis Agassiz

When chemists have brought their knowledge out of their special laboratories into the laboratory of the world, where chemical combinations are and have been through all time going on in such vast proportions,-when physicists study the laws of moisture, of clouds and storms, in past periods as well as in the present,-when, in short, geologists and zoologists are chemists and physicists, and vice versa,-then we shall learn more of the changes the world has undergone than is possible now that they are separately studied. — Louis Agassiz

Lay aside all conceit Learn to read the book of Nature for yourself. Those who have succeeded best have followed for years some slim thread which once in a while has broadened out and disclosed some treasure worth a life-long search. — Louis Agassiz

In 1847 I gave an address at Newton, Mass., before a Teachers' Institute conducted by Horace Mann. My subject was grasshoppers. I passed around a large jar of these insects, and made every teacher take one and hold it while I was speaking. If any one dropped the insect, I stopped till he picked it up. This was at that time a great innovation, and excited much laughter and derision. There can be no true progress in the teaching of natural science until such methods become general. — Louis Agassiz

Facts are stupid until brought into connection with some general law. — Louis Agassiz

It is the job of prophets and scientists alike to proclaim the glories of God. — Louis Agassiz

It must be for truth's sake, and not for the sake of its usefulness to humanity, that the scientific man studies Nature. The application of science to the useful arts requires other abilities, other qualities, other tools than his; and therefore I say that the man of science who follows his studies into their practical application is false to his calling. The practical man stands ever ready to take up the work where the scientific man leaves it, and adapt it to the material wants and uses of daily life. — Louis Agassiz

Every great scientific truth goes through three stages. First, people say it conflicts with the Bible. Next they say it has been discovered before. Lastly they say they always believed it. — Louis Agassiz

The glacier was God's great plough set at work ages ago to grind, furrow, and knead over, as it were, the surface of the earth. — Louis Agassiz

The world is the geologist's great puzzle-box; he stands before it like the child to whom the separate pieces of his puzzle remain a mystery till he detects their relation and sees where they fit, and then his fragments grow at once into a connected picture beneath his hand. — Louis Agassiz

Today our duty is to destroy the myth of evolution, considered as a simple, understood, and explained phenomenon which keeps rapidly unfolding before us. Biologists must be encouraged to think about the weaknesses and extrapolations that theoreticians put forward or lay down as established truths. The deceit is sometimes unconscious, but not always, since some people, owing to their sectarianism, purposely overlook reality and refuse to acknowledge the inadequacies and falsity of their beliefs. — Louis Agassiz

The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts, to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge. — Louis Agassiz

In-depth studies have an influence on general ideas, whereas theories, in turn, in order to maintain themselves, push their spectators to search for new evidence. The mind's activity that is maintained by the debates about these works, is probably the source of the greatest joys given to man to experience on Earth. — Louis Agassiz

A smattering of everything is worth little. It is a fallacy to suppose that an encyclopaedic knowledge is desirable. The mind is made strong, not through much learning, but by the thorough possession of something. — Louis Agassiz

I hail with joy- for I am a temperance man and a friend of temperance-I hail with joy the efforts that are being made to raise wine in the country. I believe that when you have everywhere cheap, pure, unadulterated wine, you will no longer have need for either prohibitory or license laws. — Louis Agassiz

I may say that here, as in most cases where the operations of nature interfere with the designs of man, it is not by a direct intervention on our part that we may remedy the difficulties, but rather by a precise knowledge of their causes, which may enable us, if not to check, at least to avoid the evil consequences. — Louis Agassiz
