I am ignorant of how I was formed and how I was born. Through a quarter of my lifetime I was absolutely ignorant of the reasons for everything I saw and heard and felt, and was merely a parrot prompted by other parrots... When I sought to advance along that infinite course, I could neither find one single footpath or fully discover one single object, and from the upward leap I made to contemplate eternity I fell back into the abyss of my ignorance.
