Descartes Quotes

Heidegger surf-boards along on the electronic wave as triumphantly as Descartes rode the mechanical wave. (Marshall McLuhan)
Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served. View quote
Arthur Schopenhauer
In Calvinism and sectarianism man became more and more transformed into an abstract moral subject, as in Descartes he was considered an epistemological subject. View quote
Paul Tillich
My main professional interest during the 1970s has been in the dramatic change of concepts and ideas that has occurred in physics during the first three decades of the century, and that is still being elaborated in our current theories of matter. The new concepts in physics have brought about a profound change in our world view; from the mechanistic conception of Descartes and Newton to a holistic and ecological view, a view which I have found to be similar to the views of mystics of all ages and traditions.

Fritjof Capra
Bacon, Locke, Descartes, Hume, and all the others knew they were giving rights to vulgarity. But in so doing-in addition to caring for man's well-being-they were providing rights for themselves. View quote
Allan Bloom
The analytical geometry of Descartes and the calculus of Newton and Leibniz have expanded into the marvelous mathematical method-more daring than anything that the history of philosophy records-of Lobachevsky and Riemann, Gauss and Sylvester. Indeed, mathematics, the indispensable tool of the sciences, defying the senses to follow its splendid flights, is demonstrating today, as it never has been demonstrated before, the supremacy of the pure reason.

Nicholas Murray Butler
When people say that animal rescuers are crazy, what they really mean is that animal rescuers share a number of fundamental beliefs that makes them easy to marginalize. Among those is the belief that Rene Descartes was a jackass. View quote
Steven Kotler
Descartes spent far too much time in bed subject to the persistent hallucination that he was thinking. You are not free from a similar disorder. View quote
Flann O'Brien
I would inquire of reasonable persons whether this principle: Matter is naturally wholly incapable of thought, and this other: I think, therefore I am, are in fact the same in the mind of Descartes, and in that of St. Augustine, who said the same thing twelve hundred years before. View quote
Blaise Pascal
We have seen that language is something precious because it allows us to express ourselves; but it is fatal when one allows oneself to be completely led astray by it, because then it prevents one from expressing oneself. Language is the source of the prejudices and haste which Descartes thought of as the sources of error. View quote
Simone Weil
The ancient Greeks knew the laws that govern the propagation of light in a uniform medium and upon its reflection. However, the law governing the refraction of light as it passes from one transparent medium to another was unknown until the last century. Snell discovered it, Descartes tried to explain it and Fermat criticized his explanation. Since then, many great geometers have researched the problem, although no one has yet found a way of harmonizing the law of refraction with more fundamental laws that Nature must obey. (Pierre Louis Maupertuis)
It is interesting to note that Newton was not impressed by Descartes' great argument for God's existence derived from the idea of a perfect Being, nor by other metaphysical arguments that we have mentioned; yet Newton's own arguments for God's existence from the uniformity and suitability of different parts of the universe would not have seemed like proofs to Descartes.

Pierre Louis Maupertuis
The first idea was not our own. Adam In Eden was the father of Descartes And eve made air the mirror of herself, Of her sons and of her daughters. View quote
Wallace Stevens
There's a necessity for physical experience and a recourse to exemplary cases of bodily ascesis to understand and make understood a type of emptying of the mind, an emptying that is required if the mind is to think. This obviously has nothing to do with tabula rasa, with what Descartes (vainly) wanted to be a starting from scratch on the part of knowing thought. View quote
Jean-François Lyotard
All the men who are now called discoverers, in every matter ruled by thought, have been men versed in the minds of their predecessors, and learned in what had been before them. There is not one exception. I do not say that every man has made direct acquantance with the whole of his mental ancestry... But... it is remarkable how many of the greatest names in all departments of knowledge have been real antiquaries in their several subjects. I may cite among those... in science, Aristotle, Plato, Ptolemy, Euclid, Archimedes, Roger Bacon, Copernicus, Francis Bacon, Ramus, Tycho Brahe, Galileo, Napier, Descartes, Leibnitz, Newton, Locke.

Augustus De Morgan
What is philosophy? This is a notoriously difficult question. One of the easiest ways of answering it is to say that philosophy is what philosophers do, and then point to the writings of Plato, Aristotle, Descartes, Hume, Kant, Russell, Wittgenstein, Sartre, and other famous philosophers. However, this answer is unlikely to be of much use to you if you are just beginning the subject, as you probably won't have read anything by these writers. View quote
Nigel Warburton
Newton and Descartes started to try and prove that God existed in the same way as they would try and prove something in the laboratory or with their mathematics ... And when you try and mix science and religion you get bad science and bad religion. The two are doing two different things. ... Science can give you a diagnosis of cancer. It can even cure your disease, but it cannot touch your grief and disappointment, nor can it help you to die well. View quote
Karen Armstrong
That Descartes' Cartesian way of looking at animals, like they're machines... It is outdated, and quite frankly, 100% insane. Because, if we all understand that animals use their eyes to see, ears to hear, noses to smell, mouths to eat, legs to walk, feathers to fly, fins to swim, genitalia to procreate, bowels to defecate.. I'm always perplexed that most people don't believe that they can also use their brains to think, feel, be rational, be aware and be self-aware! Am I supposed to believe, that every body part of an animal functions just like it's supposed to, except the brain? View quote
Gary Yourofsky
But understanding and explaining motives does not compromise freedom; nor does even predicting acts necessarily do so. A person committed to a political cause may vote predictably, and intelligibly in an election. He does not vote less freely than someone that flips a coin at the last minute. So if we find comparison with animals any help in understanding motives, it will not mean that conduct is not free. And since animals are not (as Descartes supposed) automata, the issue of freedom does not make comparing man with any other species and downgrading irrelevance. View quote
Mary Midgley
Descartes may have made a lot of mistakes, but he was right about this: you cannot doubt the existence of your own consciousness. That's the first feature of consciousness, it's real and irreducible. You cannot get rid of it by showing that it's an illusion in a way that you can with other standard illusions. View quote
John Searle
The one who contributed most to break down the barrier between physical method and metaphysical method, and to confound their domains, so clearly distinguished in the Aristotelian philosophy, was surely Descartes. (Pierre Duhem)
Just as Hegel later developed the metaphysical and rationalistic bases of the Spinoza philosophy giving the only possible refutation to Spinozism, that is, by converting the substance of Spinoza into an absolute idea, into the absolute spirit, and in this way, presented an antithesis to Spinozist teaching, so in his time, Spinoza presented an antithesis with respect to Descartes, but a materialistic antithesis. View quote
Baruch Spinoza
There is a doctrine about the nature and place of the mind which is prevalent among theorists, to which most philosophers, psychologists and religious teachers subscribe with minor reservations. Although they admit certain theoretical difficulties in it, they tend to assume that these can be overcome without serious modifications being made to the architecture of the theory.... The official doctrine, which hails chiefly from Descartes, is something like this. With the doubtful exceptions of idiots and infants in arms every human being has both a body and a mind. Some would prefer to say that every human being is both a body and a mind. His body and his mind are ordinarily harnessed together, but after the death of the body his mind may continue to exist and function. View quote
Gilbert Ryle
And then, a little Jew, with a long nose and a pale complexion, Poor but satisfied, pensive and reserved, A subtle but hollow spirit, less read than celebrated, Hidden under the mantle of Descartes, his mentor, Walking with measured steps, comes close to the great being: Excuse me, he says, addressing him in a whisper, But I think, just between us, that you do not exist at all. View quote
Baruch Spinoza
In the strident world of seventeenth-century philosophy, the mind-body problem was not a word puzzle that could be safely relegated to undergraduate classes. For men such as Descartes, Malebranche, and Leibniz, solving the mind-body problem was vital to preserving the theological and political order inherited from the Middle Ages and, more generally, to protecting human self-esteem in the face of an increasingly truculent universe. For Spinoza, it was a means of destroying that same order and discovering a new foundation for human worth. View quote
