Principles of the 14th July Revolution (1959)
“This much will I say for myself — and on this point I do not blush for praising myself — that I have never philosophized save for the sake of philosophy, nor have I ever desired or hoped to secure from my studies and my laborious researches any profit or fruit save cultivation of mind and knowledge of the truth — things I esteem more and more with the passage of time. I have also been so avid for this knowledge and so enamored of it that I have set aside all private and public concerns to devote myself completely to contemplation; and from it no calumny of jealous persons, nor any invective from enemies of wisdom has ever been able to detach me.”
Dabo hoc mihi, et me ipsum hac ex parte laudare nihil erubescam, me numquam alia de causa philosophatum nisi ut philosopharer, nec ex studiis meis, ex meis lucubrationibus, mercedem ullam aut fructum vel sperasse alium vel quesiisse, quam animi cultum et a me semper plurimum desideratae veritatis cognitionem. Cuius ita cupidus semper et amantissimus fui ut, relicta omni privatarum et publicarum rerum cura, contemplandi ocio totum me tradiderim; a quo nullae invidorum obtrectationes, nulla hostium sapientiae maledicta, vel potuerunt ante hac, vel in posterum me deterrere poterunt.
