• Whenever anyone has offended me, I try to raise my soul so high that the offense cannot reach it.


  • By ‘God’, I understand, a substance which is infinite, independent, supremely intelligent, supremely powerful, and which created both myself and everything else […] that exists. All these attributes are such that, the more carefully I concentrate on them, the less possible it seems that they could have originated from me alone. So, from what has been said it must be concluded that God necessarily exists.


  • I have concluded the evident existence of God, and that my existence depends entirely on God in all the moments of my life, that I do not think that the human spirit may know anything with greater evidence and certitude.


  • If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.


  • It is possible that I am dreaming right now and that all of my perceptions are false.


  • How can you be certain that your whole life is not a dream?


  • Some years ago I was struck by the large number of falsehoods that I had accepted as true in my childhood, and by the highly doubtful nature of the whole edifice that I had subsequently based on them. I realized that it was necessary, once in the course of my life, to demolish everything completely and start again right from the foundations if I wanted to establish anything at all in the sciences that was stable and likely to last.


  • The chief cause of human errors is to be found in the prejudices picked up in childhood.


  • Doubt is the origin of wisdom


  • If I simply refrain from making a judgment in cases where I do not perceive the truth with sufficient clarity and distinctness, then it is clear that I am behaving correctly and avoiding error.


  • The only thing that I know, is that I know nothing


  • Conquer yourself rather than the world.


  • And as it is the most generous souls who have most gratitude, it is those who have most pride, and who are most base and infirm, who most allow themselves to be carried away by anger and hatred.


  • Divide each difficulty into as many parts as is feasible and necessary to resolve it.


  • The reading of all good books is indeed like a conversation with the noblest men of past centuries who were the authors of them, nay a carefully studied conversation, in which they reveal to us none but the best of their thoughts.


  • I think; therefore I am. ( “Cogito ergo sum” )


  • I know that I exist; the question is, What is this “I” that “I” know.


  • ..it is certain that I am really distinct from my body, and can exist without it.

René Descartes was a French philosopher, mathematician and scientist. Dubbed the father of modern Western philosophy, much of subsequent Western Philisophy is a response to his writings, which are studied closely to this day. A native of the Kingdom of France, he spent about 20 years (1629–49) of his life in the Dutch Republic after serving  for a while in the Dutch States Army of Maurice of Nassau, Prince of Orange and the Stadholder of the United Provinces. He is generally considered one of the most notable intellectual representatives of the Dutch Golden Age.

Descartes’ Meditations on First Philosophy continues to be a standard text at most university philosophy departments. Descartes’ influence in mathematics is equally apparent; the Cartesian coordinate system  was named after him. He is credited as the father of  analytical geometry, the bridge between algebra and geometry, used in the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the scientific revolution.
