30 Quotes on Knowledge and Nature

"Many people think that the progress of the human race is based on experiences of an empirical, critical nature, but I say that true knowledge is to be had only through a philosophy of deduction. For it is intuition that improves the world, not just following a trodden path of thought. Intuition makes us look at unrelated facts and then think about them until they can all be brought under one law. To look for related facts means holding onto what one has instead of searching for new facts. Intuition is the father of new knowledge, while empiricism is nothing but an accumulation of old knowledge. Intuition, not intellect, is the 'open sesame' of yourself."

— Albert Einstein

"Not only must philosophy be in agreement with our empirical knowledge of Nature, but the origin and formation of the Philosophy of Nature presupposes and is conditioned by empirical physics. However, the course of a science's origin and the preliminaries of its construction are one thing, while the science itself is another. In the latter, the former can no longer appear as the foundation of the science; here, the foundation must be the necessity of the Concept."

— Georg Wilhelm Friedrich Hegel

"Let us give Nature a chance; she knows her business better than we do."

— Michel de Montaigne

"Nature knows no indecencies; man invents them."

"You will know that the divine is so great and of such a nature that it sees and hears everything at once, is present everywhere, and is concerned with everything."

"Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or in thought of the course of nature. Beyond this he neither knows anything nor can do anything."

— Francis Bacon

"We have gathered within the walls of the Communist Academy and are devoting this evening to Spinoza's memory not from the considerations which guided the organizers of the Hague celebration but from quite different considerations; for us Spinoza is essentially a great atheist and materialist. In this appraisal of Spinoza I am in complete agreement with Plekhanov. In all of Plekhanov's works, as I know, the fundamental thought is emphasized that Marxism, considered as a world‑view, is nothing other than a 'variety of Spinozism.' But I shall set this question aside for the moment, in order to cite a passage from Plekhanov's preface to my Introduction to Philosophy in which he sharply criticizes the historians of philosophy who have numbered Spinoza among the idealists. 'With the present universal prevalence of idealism,' he says, 'it is quite natural that the history of philosophy should now be interpreted from the idealistic point of view. As a consequence, Spinoza his long since been numbered among the idealists. Hence, certain readers will probably be very much surprised to learn that I understand Spinoza in the materialistic sense; yet this is the only correct understanding of Spinozism. 'As early as 1843 Feuerbach asserted his fundamental conviction that the teaching of Spinoza was "an expression of the materialistic conceptions of the modern age." Of course, even Spinoza did not escape the influence of his time. His materialism, as Feuerbach remarked, was clothed in a theological costume, but the important thing was that, in any case, he eliminated the dualism of mind and nature. Nature in Spinoza is called God, but extension is one of the attributes of this God. And this constitutes the radical difference between Spinozism and idealism.'"

— Baruch Spinoza

"Nature does nothing in vain, and in the use of means to her goals she is not prodigal. Her giving to man reason and the freedom of the will which depends upon it is clear indication of her purpose. Man accordingly was not to be guided by instinct, not nurtured and instructed with ready-made knowledge; rather, he should bring forth everything out of his own resources."

— Immanuel Kant

"It is manifest that there is no danger at all in the proportion or quantity of knowledge, how large soever, lest it should make it swell or out-compass itself; no, but it is merely the quality of knowledge, which, be it in quantity more or less, if it be taken without the true corrective thereof, hath in it some nature of venom or malignity, and some effects of that venom, which is ventosity or swelling. This corrective spice, the mixture whereof maketh knowledge so sovereign, is charity, which the Apostle immediately addeth to the former clause; for so he saith, "Knowledge bloweth up, but charity buildeth up."

— Francis Bacon

"The controlling Intelligence understands its own nature, and what it does, and whereon it works."

— Marcus Aurelius

"If generation were in a straight line only, and there were no compensation or circle in nature, no turn or return into one another, then you know that all things would at last have the same form and pass into the same state, and there would be no more generation of them."

"When Galilei let balls of a particular weight, which he had determined himself, roll down an inclined plain, or Torricelli made the air carry a weight, which he had previously determined to be equal to that of a definite volume of water; or when, in later times, Stahl changed metal into lime, and lime again into metals, by withdrawing and restoring something, a new light flashed on all students of nature. They comprehended that reason has insight into that only, which she herself produces on her own plan, and that she must move forward with the principles of her judgments, according to fixed law, and compel nature to answer her questions, but not let herself be led by nature, as it were in leading strings, because otherwise accidental observations made on no previously fixed plan, will never converge towards a necessary law, which is the only thing that reason seeks and requires. Reason, holding in one hand its principles, according to which concordant phenomena alone can be admitted as laws of nature, and in the other hand the experiment, which it has devised according to those principles, must approach nature, in order to be taught by it: but not in the character of a pupil, who agrees to everything the master likes, but as an appointed judge, who compels the witnesses to answer the questions which he himself proposes. Therefore even the science of physics entirely owes the beneficial revolution in its character to the happy thought, that we ought to seek in nature whatever reason must learn from nature, and could not know by itself, and that we must do this in accordance with what reason itself has originally placed into nature. Thus only has the study of nature entered on the secure method of a science, after having for many centuries done nothing but grope in the dark."

— Immanuel Kant

"Once upon a time, in some out of the way corner of that universe which is dispersed into numberless twinkling solar systems, there was a star upon which clever beasts invented knowing. That was the most arrogant and mendacious minute of "world history," but nevertheless, it was only a minute. After nature had drawn a few breaths, the star cooled and congealed, and the clever beasts had to die. One might invent such a fable, and yet he still would not have adequately illustrated how miserable, how shadowy and transient, how aimless and arbitrary the human intellect looks within nature. There were eternities during which it did not exist. And when it is all over with the human intellect, nothing will have happened."

— Friedrich Nietzsche

"It is true that numerous instances are not always necessary to establish a law, provided the essential and relevant circumstances can easily be disentangled. But, in history, so many circumstances of a small and accidental nature are relevant, that no broad and simple uniformities are possible. Where our main endeavour is to discover general laws, we regard these as intrinsically more valuable than any of the facts which they inter-connect. In astronomy, the law of gravitation is plainly better worth knowing than the position of a particular planet on a particular night, or even on every night throughout a year. There are in the law a splendour and simplicity and sense of mastery which illuminate a mass of otherwise uninteresting details... But in history the matter is far otherwise... Historical facts, many of them, have an intrinsic value, a profound interest on their own account, which makes them worthy of study, quite apart from any possibility of linking them together by means of causal laws."

— Bertrand Russell

"One of Spinoza's more famous, influential and incendiary doctrines concerns the origin and status of Scripture. The Bible, Spinoza argues in the Theological-Political Treatise, was not literally authored by God. God or Nature is metaphysically incapable of proclaiming or dictating, much less writing, anything. Scripture is not ‘a message for mankind sent down by God from heaven’. Rather, it is a very mundane document. Texts from a number of authors of various socio-economic backgrounds, writing at different points over a long stretch of time and in differing historical and political circumstances, were passed down through generations in copies after copies after copies. Spinoza supplements his theory of the human origins of Scripture with an equally deflationary account of its authors. The prophets were not especially learned individuals. They did not enjoy a high level of education or intellectual sophistication. They certainly were not philosophers or physicists or astronomers. There are no truths about nature or the cosmos to be found in their writings . Neither are they a source of metaphysical or even theological truths. The prophets often had naïve, even philosophically false beliefs about God."

— Baruch Spinoza

"Unlike the La Pérouse expedition the Conquistadors sought not knowledge but Gold. They used their superior weapons to loot and murder, in their madness they obliterated a civilisation. In the name of piety, in a mockery of their religion, the Spaniards utterly destroyed a society with an Art, Astronomy and Architecture the equal of anything in Europe. We revile the Conquistadors for their cruelty and shortsightedness, for choosing death. We admire La Pérouse and the Tlingit for their courage and wisdom, for choosing life. The choice is with us still, but the civilisation now in jeopardy is all humanity. As the ancient myth makers knew we're children equally of the earth and the sky. In our tenure on this planet we've accumulated dangerous evolutionary baggage, propensities for aggression and ritual, submission to leaders, hostility to outsiders, all of which puts our survival in some doubt. But we've also acquired compassion for others, love for our children, a desire to learn from history and experience and a great soaring passionate intelligence, the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits. National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national identifications are a little difficult to support when we see our Earth as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and the citadel of the stars. There are not yet obvious signs of extraterrestrial intelligence and this makes us wonder whether civilisations like ours rush inevitably headlong into self-destruction."

"What do we mean by “understanding” something? We can imagine that this complicated array of moving things which constitutes “the world” is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is to watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics. Even if we knew every rule, however, we might not be able to understand why a particular move is made in the game, merely because it is too complicated and our minds are limited. If you play chess you must know that it is easy to learn all the rules, and yet it is often very hard to select the best move or to understand why a player moves as he does. So it is in nature, only much more so."

— Richard Feynman

"M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry."

— René Descartes

"It always seems to me extreme rashness on the part of some when they want to make human abilities the measure of what nature can do. On the contrary, there is not a single effect in nature, even the least that exists, such that the most ingenious theorists can arrive at a complete understanding of it. This vain presumption of understanding everything can have no other basis than never understanding anything. For anyone who had experienced just once the perfect understanding of one single thing, and had truly tasted how knowledge is accomplished, would recognize that of the infinity of other truths he understands nothing."

— Galileo Galilei

"he first philosophers, in investigating the truth and the nature of things, wandered, as if led by ignorance, into a certain... path. Hence, they say that no being is either generated or corrupted, because it is necessary that what is generated should be generated either from being or non-being: but both these are impossible; for neither can being be generated, since it already is; and from nothing, nothing can be generated... And thus... they said that there were not many things, but that being alone had a subsistence. ...the ancient philosophers ...through this ignorance added so much to their want of knowledge, as to fancy that nothing else was generated or had a being; but they subverted all generation."

"It is not easy to determine the nature of music, or why anyone should have a knowledge of it."

"Most men and women, by birth or nature, lack the means to advance in wealth and power, but all have the ability to advance in knowledge."

"To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature. … If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in."

— Richard Feynman

"If any man could arrive at the exterior limit, or take the wings of a bird and fly upward, like a fish who puts his head out and sees the world, he would see a world beyond; and, if the nature of man could sustain this sight, he would acknowledge that this was the place of the true heaven and the true light and the true stars. For this earth, and the stones, and the entire region which surrounds us, are spoilt and corroded..."

"While I am describing to you how Nature works, you won't understand why Nature works that way. But you see, nobody understands that."

— Richard Feynman

"Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected. … The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth”."

— Richard Feynman

"I have repeatedly said that in my opinion the idea of a personal God is a childlike one. You may call me an agnostic, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being."

— Albert Einstein

"Electric current, after passing into the earth travels to the diametrically opposite region of the same and rebounding from there, returns to its point of departure with virtually undiminished force. The outgoing and returning currents clash and form nodes and loops similar to those observable on a vibrating cord. To traverse the entire distance of about twenty-five thousand miles, equal to the circumference of the globe, the current requires a certain time interval, which I have approximately ascertained. In yielding this knowledge, nature has revealed one of its most precious secrets, of inestimable consequence to man. So astounding are the facts in this connection, that it would seem as though the Creator, himself, had electrically designed this planet just for the purpose of enabling us to achieve wonders which, before my discovery, could not have been conceived by the wildest imagination."

— Nikola Tesla

"The very starting-point of Spinoza, the search and discovery of the cause of causes, is hateful to Kant, who states that scientists err when they follow this path. He presumes and presupposes nothing, not even the possibility of the oneness of nature. Transcendental philosophy to him is only the theory of recognition of the possibility of nature itself. Spinoza, on the other hand, presumes and presupposes everything God, nature, its phenomena, and their different relationships. He begins with the supreme cause, without knowing whether it is and what it is. He sets out rationalistically and dogmatically while Kant begins critically. Kant is complicated, abstruse, and often dark, while Spinoza is simple, plain, and full of light. Kant's philosophy can be accepted either entirely or partly, but Spinoza's philosophy can be accepted only entirely. There can be no left or right Spinozists as there are left and right Kantians or Hegelians. In spite of its mathematical form, Spinozism is, in the last analysis, an experience of man's soul, while Kantianism is the product of man's critical mind. The soul is often disturbed and subject to varying moods, while man's mind is more rigid. Feeling is common to all people, but intellectual meditations are the heritage of the few. We can thus understand Spinoza's influence upon the entire fabric of modern culture with the exception of the plastic arts and music, and Kant's influence upon philosophy alone. Spinoza created a new world-picture, Kant only a new school of philosophy. Kant definitely established the frontiers of the human mind, but Spinoza reconstructed a new world out of an old one. Everyone is interested in Spinoza, but only philosophers are concerned with Kant."

— Baruch Spinoza

"For such is the nature of men, that howsoever they may acknowledge many others to be more witty, or more eloquent, or more learned; Yet they will hardly believe there be many so wise as themselves: For they see their own wit at hand, and other men's at a distance."

— Thomas Hobbes
