Everything can be forgiven in this world, save telling the truth.
Every truth is simple – Is that not doubly a lie?[“Alle Wahrheit ist einfach.” – Ist das nicht zwiefach eine Lüge?]
Every thing possible to be believed is an image of truth.
Every man can have his own peculiar truth; and yet it is always the same.
Error is related to truth as sleep to waking.
Eliminate all other factors, and the one which remains must be the truth.
Devotion to truth is the hallmark of morality, then there is no greater, nobler, more heroic form of devotion than the act of a man who assumes the responsibility of thinking.
But what after all are man’s truths? They are his irrefutable errors.[Was sind denn zuletzt die Wahrheiten des Menschen? – Es sind die unwiderlegbaren Irrthümer des Menschen.]
But I hope that it will also be demonstrated soon that in my experiments in the West I was not merely beholding a vision, but had caught sight of a great and profound truth.
Beyond a doubt truth bears the same relation to falsehood as light to darkness.[Sanza dubbio tal proportione è dalla verità alla bugia, qual è dalla luce alle tenebre.]
Better to get hurt by the truth than comforted with a lie.
Being in a minority, even a minority of one, did not make you mad. There was truth and there was untruth, and if you clung to the truth even against the whole world, you were not mad.
