Tüm yöntem aklın birtakım gerçeklere varmak için çabasını yönlendirmek zorunda olduğu konuların sırasına ve konumuna dayanır. Bunu sürdürebilmek için… - René Descartes

But this could not be the case with-the idea of a nature more perfect than myself; for to receive it from nothing was a thing manifestly impossible; and, because it is not less repugnant that the more perfect should be an effect of, and dependence on the less perfect, than that something should proceed from nothing, it was equally impossible that I could hold it from myself:

I will follow this strategy until I discover something that is certain or, at least, until I discover that it is certain only that nothing is certain.

Λαχταρούσα όσο κάνείς άλλος να κατακτήσω τος ουρανούς όμως, αφού έμαθα με απόλυτη βεβαιότητα ότι ο δρόμος είναι ανοιχτός τόσο για τους αδαείς όσο και για τους περισσότερο μορφωμένους, και ότι οι αλήθειες που αποκαλύπτονται και οι οποίες οδηγούν εκεί, είναι υπεράνω της διάνοιας μας, δεν θα τολμούσα να τις υποβάλω στους αδύναμους συλλογισμούς μου.
