“Each problem that I solved became a rule, which served afterwards to solve other problems.”

“In asking for a relic of Descartes, the chevalier de Terlon was standing at the crossroads of the ancient and modern. He was applying to a modern thinker - the inventor of analytic geometry, no less - a primitive tradition that extends back not only to the institutionalization of Christianity in the fourth century, when Christians first broke into the tombs of saints to gather relics, but farther still, beyond the horizon of recorded history. The request is all the stranger for the fact that the man whose remains were treated in this quasisaintlike way would go down in history as the progenitor of materialism, rationalism, and a whole tradition that looked on such veneration as nonsense.”

“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.”

“If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of inspiration. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.”

“That is why I don't believe much in what Mr. Descartes said: "I think, therefore I am." I think, therefore I'm lost in my thinking. I'm not there.”

“Gratitude is a species of love, excited in us by some action of the person for whom we have it, and by which we believe that he has done some good to us, or at least that he has had the intention of doing so. Passions, III, 193. XI, 473-474. Trans. John Morris”

“Freud introduced the unconscious, which in effect dethroned man as the uncontested master of his own rational faculties. Instead , our lives and our decisions, our loves and our hates, are more often the result of forces working elsewhere than in our conscious mind, and we are the dupes of those forces, rather than their master. (...) Indeed, thinking, as Descartes conceived it, accounts for considerably less than half the story of our being in the world.”

“My laps-meter, the first caliper of the soul and the first hope of bridging the dread chasm that has rent the soul of Western man ever since the famous philosopher Descartes ripped body loose from mind and turned the very soul into a ghost that haunts its own house.”

“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.”

“He passed the lighter down the table until Descartes held it in one hand while setting the greasy cylinder down on the table. After smoothing it out, Descartes sparked up the lighter. With the lighter drawn near the grease, the aroma of burnt hair filled the board room.”

“Some care is needed in using Descartes' argument. "I think, therefore I am" says rather more than is strictly certain. It might seem as though we are quite sure of being the same person to-day as we were yesterday, and this is no doubt true in some sense. But the real Self is as hard to arrive at as the real table, and does not seem to have that absolute, convincing certainty that belongs to particular experiences.”
