Descartes implicitly assumed a complete correspondence existed between — René Descartes

"Doubt is the origin of wisdom and Latin: Dubium sapientiae initium. This has been attributed to Descartes, including here previously, but no original attribution has been found. Descartes Meditationes de prima philosophia has been cited as the source of Dubium sapientiae initium, but this quote is not found in this work."

"[E]arly analytic geometers—Descartes in particular—did not accept that geometry could be based on numbers or algebra. Perhaps the first to take the idea of arithmetizing geometry seriously was Wallis..."

"An optimist may see a light where there is none, but why must the pessimist always run to blow it out?"

"He has given us only some beautiful beginnings, without getting to the bottom of things. ...he is still far from the true analysis and the general art of discovery. For I am convinced that his mechanics is full of errors, that his physics goes too fast, that his geometry is too narrow, and that his metaphysics is all these things."

"Modesty was not a condition from which Descartes suffered."

"René Descartes played his part in the world as a man in a mask. The phrase is his own. It implied no conscious duplicity but a certain apartness rendering him incapable of taking his share unreservedly in the game of life. His attitude was that of an unimpassioned spectator. He looked on and learned while others struggled for the stakes. A born recluse, he remained solitary even in the throng of social intercourse. ...The transport felt by Bacon at the glorious vision of a future in which the harvest he had sown would be reaped was not shared by Descartes. He indeed held himself to be the sower and the reaper in one. Calmly, and with settled conviction, he claimed to have virtually expounded all the phenomena of nature. He had crossed the frontier of the new world of knowledge; those who desired to follow him needed only to purge their eyes with the euphrasy of methodic doubt in order to obtain those crystal-clear intuitions from which, by sure reasoning, universal science could be deduced. ...He was a mathematician of first rate originality and power. ...Unfortunately, however, he was misled by false analogies of thought; he sought to universalise what was by its nature special and restricted; and thus pursued the flitting vision of a deceptive unity in knowledge. As the upshot, he gave to his philosophy a pseudo-mathematical character, and sacrificed the solid achievement of much by aiming at the illusory certainty of everything."

"What say you? It is useless? Ay, I know But who fights ever hoping for success? I fought for lost cause, and for fruitless quest! You there, who are you! — You are thousands! Ah! I know you now, old enemies of mine! Falsehood! Have at you! Ha! and Compromise! Prejudice, Treachery! … Surrender, I? Parley? No, never! You too, Folly, — you? I know that you will lay me low at last; Let be! Yet I fall fighting, fighting still!"

"Ministers who deal with billions of dollars cannot be paid low salaries without risking a system malfunction. Low salaries will not attract able men who are or can be successful in their professions or business. Low salaries will draw in the hypocrites who sweet talk their way into power in the name of public services, but once in charge will show their true colour, and ruin the country. This has happened in many countries."

"In a Thumbnail Sketch here is [the Multiple Drafts theory of consciousness] so far:There is no single, definitive "stream of consciousness," because there is no central Headquarters, no Cartesian Theatre where "it all comes together" for the perusal of a Central Meaner. Instead of such a single stream (however wide), there are multiple channels in which specialist circuits try, in parallel pandemoniums, to do their various things, creating Multiple Drafts as they go. Most of these fragmentary drafts of "narrative" play short-lived roles in the modulation of current activity but some get promoted to further functional roles, in swift succession, by the activity of a virtual machine in the brain. The seriality of this machine (its "von Neumannesque" character) is not a "hard-wired" design feature, but rather the upshot of a succession of coalitions of these specialists.The basic specialists are part of our animal heritage. They were not developed to perform peculiarly human actions, such as reading and writing, but ducking, predator-avoiding, face-recognizing, grasping, throwing, berry-picking, and other essential tasks. They are often opportunistically enlisted in new roles, for which their talents may more or less suit them. The result is not bedlam only because the trends that are imposed on all this activity are themselves part of the design. Some of this design is innate, and is shared with other animals. But it is augmented, and sometimes even overwhelmed in importance, by microhabits of thought that are developed in the individual, partly idiosyncratic results of self-exploration and partly the predesigned gifts of culture. Thousands of memes, mostly borne by language, but also by wordless "images" and other data structures, take up residence in an individual brain, shaping its tendencies and thereby turning it into a mind."

"We recognize that in the reconstruction of most things – national, international, social, political – he is destined to play a commanding part. ... Its looks as if he were fated, despite his reluctance – for he is a modest man and his ambition, whatever it may be, is carefully concealed – to be a Saviour of Society, as well as an Organizer of Victory."

"I am speechless about the idea of putting music fans in jail for downloading music. It is wrong to illegally download, but the answer cannot be jail. Here in America we create new opportunities out of adversity, not punitive laws, and we should look to new technologies like Apples new Music Store for solutions. This way, innovation continues to be the hallmark of America. It is the fans that drive the success of the music business."

"We foreign journalists in Moscow used to amuse ourselves, as a matter of fact, by competing with one another as to who could wish upon one of these intelligentsia visitors to the USSR the most outrageous fantasy…One story I floated myself, for which I received considerable acclaim, was that the huge queues outside food shops came about because the Soviet workers were so ardent in building Socialism that they just wouldnt rest, and the only way the government could get them to rest for even two or three hours was organizing a queue for them to stand in. I laugh at it all now, but at the time you can imagine what a shock it was to someone like myself, who had been brought up to regard liberal intellectuals as the samurai, the absolute elite, of the human race, to find that they could be taken in by deceptions which a half-witted boy would see through in an instant…I could never henceforth regard the intelligentsia as other than credulous fools who nonetheless became the medias prophetic voices, their heirs and successors remaining so still."
