"It is a transitional time for the culture of manhood. The idea of proving one’s manhood has certainly not disappeared and is very much still with us. But at the same time, there are few outlets for men to be tested. There is no tribe of men to judge one worthy, no rites-of-passage, no proving grounds to make one’s stand. And thus we see a source of modern male anxiety: the ancient desire to prove one’s manhood meets with a world where opportunities to do so are practically non-existent."
