“Philosophizing is: rejecting false arguments.
The philosopher strives to find the liberating word, that is, the word that finally permits us to grasp what up to now has intangibly weighed down upon our consciousness.”

Variant: Every philosophical problem, when it is subjected to the necessary analysis and purification, is found either to be not really philosophical at all, or else to be, in the sense in which we are using the word, logical.

“A strong man hates no one, is enraged with no one,” whispered William.

Context: My answer to the question "Why do we philosophize?" is as follows. We philosophize for the same reason that we move and speak and laugh and eat and love.
