More quotes by Rene Descartes
Travelling is almost like talking with those of other centuries.
Rene Descartes
I hope that posterity will judge me kindly, not only as to the things which I have explained, but also to those which I have intentionally omitted so as to leave to others the pleasure of discovery.
Rene Descartes
The nature of matter, or body considered in general, consists not in its being something which is hard or heavy or coloured, or which affects the senses in any way, but simply in its being something which is extended in length, breadth and depth.
Rene Descartes
For how do we know that the thoughts which occur in dreaming are false rather than those others which we experience when awake, since the former are often not less vivid and distinct than the latter?
Rene Descartes
In order to improve the mind, we ought less to learn, than to contemplate.
Rene Descartes
A state is better governed which has few laws, and those laws strictly observed.
Rene Descartes
And I shall always hold myself more obliged to those by whose favour I enjoy uninterrupted leisure than to any who might offer me the most honourable positions in the world.
Rene Descartes
I should consider that I know nothing about physics if I were able to explain only how things might be, and were unable to demonstrate that they could not be otherwise.
Rene Descartes
Doubt is the origin of wisdom
Rene Descartes
We do not describe the world we see, we see the world we can describe.
Rene Descartes
I accept no principles of physics which are not also accepted in mathematics.
Rene Descartes

Rene Descartes
The two operations of our understanding, intuition and deduction, on which alone we have said we must rely in the acquisition of knowledge.
Rene Descartes
But possibly I am something more than I suppose myself to be.
Rene Descartes
Neither the true nor the false roots are always real sometimes they are imaginary that is, while we can always imagine as many roots for each equation as I have assigned, yet there is not always a definite quantity corresponding to each root we have imagined.
Rene Descartes
Instead I ought to be grateful to Him who never owed me anything for having been so generous to me, rather than think that He deprived me of those things or has taken away from me whatever He did not give me.
Rene Descartes
Sensations are nothing but confused modes of thinking.
Rene Descartes
If ... it is not in my power to arrive at the knowledge of any truth, I may at least do what is in my power, namely, suspend judgement.
Rene Descartes
Everything is self-evident.
Rene Descartes
Perfect numbers like perfect men are very rare.
Rene Descartes
