'Faith' means not wanting to know what is true

Deep is the well of truth and long does it take to know what has fallen into its depths

Truth is a mobile army of metaphors, metonyms, anthropomorphisms, in short a sum of human relations which have been subjected to poetic and rhetorical intensification, translation and decoration […]; truths are illusions of which we have forgotten that they are illusions, metaphors which have become worn by frequent use and have lost all sensuous vigour […]. Yet we still do not know where the drive to truth comes from, for so far we have only heard about the obligation to be truthful which society imposes in order to exist"


from, "On Truth and Lying in a Non-Moral Sense".

One can promise actions, but not feelings, for the latter are involuntary. He who promises to love forever or hate forever or be forever faithful to someone is promising something that is not in his power.

Belief in truth begins with doubting all that has hitherto been believed to be true.

The more abstract the truth you wish to teach, the more you must allure the senses to it
