I know that I know nothing - ipse se nihil scire id unum sciat - ἓν οἶδα ὅτι οὐδὲν οἶδα - Socrates

Life is nothing more than an endless wandering, it would be foolish if not childish to think we know everything, at any point in life.

Embrace the constant unknown and be skeptical to sate a untarisable desire of knowledge.
