Honesty

Honesty is the recognition of the fact that the unreal is unreal and can have no value, that neither love nor fame nor cash is a value if obtained by fraud -- that an attempt to gain a value by deceiving the mind of others is an act of raising your victims to a position higher than reality, where you become a pawn of their blindness, a slave of their non-thinking and their evasions, while their intelligence, their rationality, their perceptiveness becomes the enemies you have to dread and flee -- that you do not care to live as a dependent, lest of all a dependent on the stupidity of others, or as a fool whose source of values is the fools he succeeds in fooling -- that honesty is not a social duty, not a sacrifice for the sake of others, but the most profoundly selfish virtue man can practice: his refusal to sacrifice the reality of his own existence to the deluded consciousness of others.
