“My philosophy, in essence, is the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute.”

I like it!  The productive, noble sovereign living in harmony with the Laws of Nature and in fellowship with his neighbors.  The truth will set you free.  ;-)

5 stars is not enough to rate the sentiment. My single caveat would be — the Creator is the supreme absolute.
