The greatest minds are capable of the greatest vices as well as of the greatest virtues.
Rene DescartesIf 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 DescartesWhat then is the source of my errors? They are owing simply to the fact that, since the will extends further than the intellect, I do not contain the will within the same boundaries; rather, I also extend it to things I do not understand. Because the will is indifferent in regard to such matters, it easily turns away from the true and the good; and in this way I am deceived and I sin.
