More quotes by Rene Descartes
Perfect numbers like perfect men are very rare.
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
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
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
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
This result could have been achieved either by his [God] endowing my intellect with a clear and distinct perception of everything about which I would ever deliberate, or simply by impressing the following rule so firmly upon my memory that I could never forget it: I should never judge anything that I do not clearly and distinctly understand.
Rene Descartes
With me, everything turns into mathematics.
Rene Descartes
But possibly I am something more than I suppose myself to be.
Rene Descartes
Even if I were to suppose that I was dreaming and whatever I saw or imagined was false, yet I could not deny that ideas were truly in my mind.
Rene Descartes
I accept no principles of physics which are not also accepted in mathematics.
Rene Descartes
How do we know that anything really exists, that anything is really the way it seems ot us through our senses?
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
It's the familiar love-hate syndrome of seduction: I don't really care what it is I say, I care only that you like it.
Rene Descartes
Sensations are nothing but confused modes of thinking.
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
It is contrary to reasoning to say that there is a vacuum or space in which there is absolutely nothing.
Rene Descartes
I am thing that thinks: that is, a things that doubts,affirms, denies, understands a few things, is ignorant of many things, is willing, is unwilling, and also which imagines and has sensory perceptions.
Rene Descartes
The rainbow is such a remarkable phenomenon of nature, and its cause has been so meticulously sought after by inquiring minds throughout the ages, that I could not choose a more appropriate subject for demonstrating how, with the method I am using, we can arrive at knowledge not possessed at all by those whose writings are available to us.
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
In order to improve the mind, we ought less to learn, than to contemplate.
Rene Descartes
