It was left for the Germans to bring about a revolution of a kind never seen before: [the Nazi] revolution, devoid of ideas... and opposed to everything that is higher, better and decent; opposed to liberty, truth, and justice.
Risk! Risk anything! Care no more for the opinion of others, for those voices. Do the hardest thing on earth for you. Act for yourself. Face the truth.
The sole philosophy open to those who doubt the possibility of truth is absolute silence - even mental.
The man who strives to educate himself - and no one else can educate him - must win a certain victory over his own nature. He must learn to smile at his dear idols, analyze his every prejudice, scrap if necessary his fondest and most consoling belief, question his presuppositions, and take his chances with the truth.
I love a serious preacher, who speaks for my sake and not for his own; who seeks my salvation, and not his own vainglory. He best deserves to be heard who uses speech only to clothe his thoughts, and his thoughts only to promote truth and virtue.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.

Man has no nobler function than to defend the truth.
There is no such thing as absolute truth... People are less deceived by failing to see the truth than by failing to see its limits.

If only truth and justice were the rule, there would be no need for mercy.
We must not, therefore, wonder whether we really perceive a world, we must instead say: the world is what we perceive... To seek the essence of perception is to declare that perception is, not presumed true, but defined as access to truth.
The passion for truth has underlying it a profound conviction that what is real is best; that when we get to the heart of things we shall find there what we most need.
We must be true inside, true to ourselves, before we can know a truth that is outside us.
Seven characteristics distinguish the wise: he does not speak before his superior, does not interrupt, is only hasty to answer, asks and answers to the point, talks about first things first and about last things last, admits when he does not know, and acknowledges the truth.
I maintain, in truth, that with a smile we should instruct our youth, be very gentle when we have to blame, and not to put them in fear of virtue's name.
