"Power-lust is a weed that grows only in the vacant lots of an abandoned mind."
"I started my life with a single absolute: that the world was mine to shape in the image of my highest values and never to be given up to a lesser standard, no matter how long or hard the struggle."
"Devotion to the truth is the hallmark of morality; there is no greater, nobler, more heroic form of devotion than the act of a man who assumes the responsibility of thinking."

It exists.. it is real.. it is possible.. it's yours."
