More quotes by 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
Give me extension and motion and I will construct the universe.
Rene Descartes
How can you be certain that your whole life is not a dream?
Rene Descartes
Perfect numbers like perfect men are very rare.
Rene Descartes
Doubt is the origin of wisdom
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 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
[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
It is contrary to reasoning to say that there is a vacuum or space in which there is absolutely nothing.
Rene Descartes
A state is better governed which has few laws, and those laws strictly observed.
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
For I found myself embarrassed with so many doubts and errors that it seemed to me that the effort to instruct myself had no effect other than th eincreasing discovery of my own ignorance
Rene Descartes
So blind is the curiosity by which mortals are possessed, that they often conduct their minds along unexplored routes, having no reason to hope for success, but merely being willing to risk the experiment of finding whether the truth they seek lies there.
Rene Descartes
Situations in life often permit no delay and when we cannot determine the course which is certainly best, we must follow the one which is probably the best. This frame of mind freed me also from the repentance and remorse commonly felt by those vacillating individuals who are always seeking as worthwhile things which they later judge to be bad.
Rene Descartes
We never understand a thing so well,and make it our own, as when we have discovered it for ourselves.
Rene Descartes
Mathematics is a more powerful instrument of knowledge than any other that has been bequeathed to us by human agency.
Rene Descartes
There is a great difference between mind and body insomuch as body is by nature always divisible, and the mind is entirely indivisible.
Rene Descartes
Few look for truth many prowl about for a reputation of profundity by arrogantly challenging whichever arguments are the best.
Rene Descartes
Everything is self-evident.
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
