More quotes by Rene Descartes
Science is practical philosophy.
Rene Descartes
It is to the body alone that we should attribute everything that can be observed in us to oppose our reason.
Rene Descartes
Perfect numbers like perfect men are very rare.
Rene Descartes
Wonder is the first of all the passions.
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
De omnibus dubitandum
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
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
Hence reason also demands that, since our thoughts cannot all be true because we are not wholly perfect, what truth they do possess must inevitably be found in the thoughts we have when awake, rather than in our dreams.
Rene Descartes
We never understand a thing so well,and make it our own, as when we have discovered it for ourselves.
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
Reason is nothing without imagination.
Rene Descartes
I experienced in myself a certain capacity for judging which I have doubtless received from God, like all the other things that I possess and as He could not desire to deceive me, it is clear that He has not given me a faculty that will lead me to err if I use it aright.
Rene Descartes
It is contrary to reasoning to say that there is a vacuum or space in which there is absolutely nothing.
Rene Descartes
Sensations are nothing but confused modes of thinking.
Rene Descartes
Give me extension and motion and I will construct the universe.
Rene Descartes
The only thing we have power over in the universe is our own thoughts.
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
I was convinced that our beliefs are based much more on custom and example than on any certain knowledge.
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
