One's own independent judgment is the means by which one must choose one's actions, but it is not a moral criterion nor a moral validation; only reference to a demonstrable principle can validate one's choices.

Morality pertains only to the sphere of man's free will - only to those actions which are open to his choice.

A desire presupposes the possibility of action to achieve it; action presupposes a goal which is worth achieving.

I have no faith at all. I only hold convictions.
