More quotes by Rene Descartes
When I consider this carefully, I find not a single property which with certainty separates the waking state from the dream. How can you be certain that your whole life is not a dream?
Rene Descartes
The greatest minds, as they are capable of the highest excellencies, are open likewise to the greatest aberrations and those who travel very slowly may yet make far greater progress, provided they keep always to the straight road, than those who, while they run, forsake it.
Rene Descartes
[About Pierre de Fermat] It cannot be denied that he has had many exceptional ideas, and that he is a highly intelligent man. For my part, however, I have always been taught to take a broad overview of things, in order to be able to deduce from them general rules, which might be applicable elsewhere.
Rene Descartes
Let whoever can do so deceive me, he will never bring it about that I am nothing, so long as I continue to think I am something.
Rene Descartes
Intuition is the undoubting conception of a pure and attentive mind, which arises from the light of reason alone, and is more certain than deduction.
Rene Descartes
The principal effect of the passions is that they incite and persuade the mind to will the events for which they prepared the body.
Rene Descartes
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.
Rene Descartes
There is a difference between happiness, the supreme good, and the final end or goal toward which our actions ought to tend. For happiness is not the supreme good, but presupposes it, being the contentment or satisfaction of the mind which results from possessing it.
Rene Descartes
Give me extension and motion and I will construct the universe.
Rene Descartes
Travelling is almost like talking with those of other centuries.
Rene Descartes
If I go for the alternative which is false, then obviously I shall be in error if I take the other side, then it is by... chance that I arrive at the truth, and I shall still be at fault.... In this incorrect use of free will may be found the privation which constitutes the essence of error.
Rene Descartes
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.
Rene Descartes
Thus each truth discovered was a rule available in the discovery of subsequent ones.
Rene Descartes
I know that I exist the question is, What is this 'I' that 'I' know.
Rene Descartes
Divide each difficulty at hand into as many pieces as possible and as could be required to better solve them.
Rene Descartes
Omnia apud me mathematica fiunt.
Rene Descartes
... moral certainty is certainty which is sufficient to regulate our behaviour, or which measures up to the certainty we have on matters relating to the conduct of life which we never normally doubt, though we know that it is possible, absolutely speaking, that they may be false.
Rene Descartes
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.
Rene Descartes
A state is better governed which has few laws, and those laws strictly observed.
Rene Descartes
Science is practical philosophy.
Rene Descartes
