The 'I think, therefore I am' of Descartes, the 'I feel, therefore I am' of late eighteenth century Romanticism, and the 'I possess therefore I am' of bourgeois man are dogmas, partial at that, incorporated to define a being that is incapable of defining itself.

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.

Wallace Stevens

Heidegger surf-boards along on the electronic wave as triumphantly as Descartes rode the mechanical wave.

Marshall McLuhan

Marriage has its unknown great men, as war has its Napoleons, poetry its Chéniers, and philosophy its Descartes.

Honoré de Balzac

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 It is outdated, and quite frankly, 100% insane.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?

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.

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.

In Calvinism and sectarianism man became more and more transformed into an abstract moral subject, as in Descartes he was considered an epistemological subject.

Regulatory messages or hormones flow from specific regions of the brain to specific glands within 'hollow' nerve fibres exactly as Erasistratus, Galen and Descartes had taught.

Richard Bergland

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.

Karen Armstrong

I'm not sure if I could tell the difference—between just staring into space and thinking. We're usually thinking all the time, aren't we? Not that we live in order to think, but the opposite isn't true either—that we think in order to live. I believe, contrary to Descartes, that we sometimes think in order not to be. Staring into space might unintentionally have the opposite effect.

Haruki Murakami

The stone that Dr. Johnson once kicked to demonstrate the reality of matter has become dissipated in a diffuse distribution of mathematical probabilities. The ladder that Descartes, Galileo, Newton, and Leibniz erected in order to scale the heavens rests upon a continually shifting, unstable foundation.

Cartesian, adj. Relating to Descartes, a famous philosopher, author of the celebrated dictum, Cogito ergo sum — whereby he was pleased to suppose he demonstrated the reality of human existence. The dictum might be improved, however, thus: Cogito cogito ergo cogito sum — "I think that I think, therefore I think that I am;" as close an approach to certainty as any philosopher has yet made.

My philosophical views approach somewhat closely those of the late Countess of Conway, and hold a middle position between Plato and Democritus, because I hold that all things take place mechanically as Democritus and Descartes contend against the views of Henry More and his followers, and hold too, nevertheless, that everything takes place according to a living principle and according to final causes — all things are full of life and consciousness, contrary to the views of the Atomists.

Gottfried Wilhelm Leibniz

Hegel's lack of charity toward the instrument metaphor is not arbitrary. It represents his disenchantment with the assumption that knowledge is power and that method is the means to this end.... Descartes' conception of method, like Bacon's, is linked to this idea of knowledge as an instrument of power.... The same could be said of Locke. Hegel can rightly claim that the instrument metaphor pervades the epistemological tradition he is seeking to transcend.
