René Descartes Quotes

Conquer yourself rather than the world.

Le bon sens est la chose du monde la mieux partagée : car chacun pense en être si bien pourvu, que ceux même qui sont les plus difficiles à contenter en toute autre chose, n'ont point coutume d'en désirer plus qu'ils en ont.

Pour examiner la vérité, il est besoin, une fois dans sa vie, de mettre toutes choses en doute autant qu’il se peut.

Et nous appellerons ces choses indéfinies plutôt qu'infinies, afin de réserver à Dieu seul le nom d'infini, tant à cause que nous ne remarquons point de bornes en ses perfections, comme aussi à cause que nous somme très assurés qu'il n'y en peut avoir. Pour ce qui est des autres choses, nous savons qu'elles ne sont pas ainsi absolument parfaites, parce qu'encore que nous y remarquions quelquefois des propriétés qui nous semblent n'avoir point de limites, nous ne laissons pas de connoitre que cela procède du défaut de notre entendement, et non point de leur nature.

...the perusal of all excellent books is, as it were, to interview with the noblest men of past ages, who have written them.

Dubito ergo cogito, cogito ergo sum'
(I doubt therefore I think, I think therefore I am)

My principle has ever been to attempt to overcome myself rather than fortune and to change my desires rather than the natural order.

La lectura de todos los buenos libros es como una conversación con los mejores ingenios de los pasados siglos que los han compuesto, y hasta una conversación estudiada en la que no nos descubren sino lo más selecto de sus pensamientos. [...] Es casi lo mismo conversar con gentes de otros siglos que viajar. Pero el que emplea demasiado tiempo en viajar acaba por tornarse extranjero en su propio país; y al que estudia con demasiada curiosidad lo que se hacía en los siglos pretéritos ocúrrele de ordinario que permanece ignorante de lo que se practica en el presente

Bad books engender bad habits, but bad habits engender good books.

"I am in doubt as to the propriety of making my first meditations in the place above mentioned matter of discourse; for these are so metaphysical, and so uncommon, as not, perhaps, to be acceptable to every one. And yet, that it may be determined whether the foundations that I have laid are sufficiently secure, I find myself in a measure constrained to advert to them. I had long before remarked that, in relation to practice, it is sometimes necessary to adopt, as if above doubt, opinions which we discern to be highly uncertain, as has been already said; but as I then desired to give my attention solely to the search after truth, I thought that a procedure exactly the opposite was called for, and that I ought to reject as absolutely false all opinions in regard to which I could suppose the least ground for doubt, in order to ascertain whether after that there remained aught in my belief that was wholly indubitable. Accordingly, seeing that our senses sometimes deceive us, I was willing to suppose that there existed nothing really such as they presented to us; and because some men err in reasoning, and fall into paralogisms, even on the simplest matters of geometry, I, convinced that I was as open to error as any other, rejected as false all the reasonings I had hitherto taken for demonstrations; and finally, when I considered that the very same thoughts (presentations) which we experience when awake may also be experienced when we are asleep, while there is at that time not one of them true, I supposed that all the objects (presentations) that had ever entered into my mind when awake, had in them no more truth than the illusions of my dreams. But immediately upon this I observed that, whilst I thus wished to think that all was false, it was absolutely necessary that I, who thus thought, should be somewhat; and as I observed that this truth, I think, therefore I am ["cogito ergo sum"], was so certain and of such evidence that no ground of doubt, however extravagant, c

Like a prisoner who dreams that he is free, starts to
suspect that it is merely a dream, and wants to go on
dreaming rather than waking up, so I am content to
slide back into my old opinions; I fear being shaken out
of them because I am afraid that my peaceful sleep may
be followed by hard labour when I wake, and that I
shall have to struggle not in the light but in the
imprisoning darkness of the problems I have raised.

"that the grace of fable stirs the mind"...and..."that the perusal of excellent books is, as it were, to interview with the noblest men of past ages"

In order to improve the mind, we ought less to learn than to contemplate.

I am not a collection of members which we call the human body: I am not a subtle air distributed through these members, I am not a wind, a fire, a vapour, a breath, nor anything at all which I can imagine or conceive; because I have assumed that all these were nothing. Without changing that supposition I find that I only leave myself certain of the fact that I am somewhat.

Thus the perception of the infinite is somehow prior in me to the perception of the finite, that is, my perception of God is prior to my perception of myself. For how would I understand that I doubt and that I desire, that is, that I lack something and that I am not wholly perfect, unless there were some idea in me of a more perfect being, by comparison with which I might recognize my defects?
