The Justification of Man

I am intrigued by Nietzsche's musings in his Twilight of the Idols, but disagree with a lot of his ideas. The following quote is one train of thought though, that I am totally on board with.

"What justifies man is his reality - it will justify him eternally. How much more valuable an actual man is compared with any sort of merely desired, dreamed of, odious lie of a man? with any sort of ideal man? . . . And it is only the ideal man who offends the philosopher's taste. "

-Friedrich Nietzsche (1844 - 1900)

There is that classic idea that you can tell someone something a thousand times, but sometimes they won't get it, unless they experience it for themselves. While I have all the respect in the world for a monk who lives his life in spiritual solace, I am much more impressed by an experienced person of the world. A person who has vices and faults, accepts them, learns from them, someone who has direct first-hand experience learned through making mistakes and taking risks.
