Quotes for: intuition

To live without philosophizing is properly to have one's eyes closed and never attempt to open them.

René Descartes - Principles of Philosophy /

I dare to believe that inner joy has some secret power to win the favour of fortune.

René Descartes - Correspondance avec Élisabeth /

Good sense is, of all things among men, the most equally distributed; for every one thinks himself so abundantly provided with it, that those even who are the most difficult to satisfy in everything else, do not usually desire a larger measure of this quality than they already possess. And in this it is not likely that all are mistaken: the conviction is rather to be held as testifying that the power of judging aright and of distinguishing truth from error, which is properly what is called good sense or reason, is by nature equal in all men; and that the diversity of our opinions, consequently, does not arise from some being endowed with a larger share of reason than others, but solely from this, that we conduct our thoughts along different ways, and do not fix our attention on the same objects. For to be possessed of a vigorous mind is not enough; the prime requisite is rightly to apply it.

René Descartes - Discourse on the Method /

It is not enough to have a good mind; the main thing is to use it well.

René Descartes - Discourse on the Method /

The reading of all good books is like a conversation with the finest minds of past centuries.

René 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.
