"Nonconformity is an empty goal, and rebellion against prevailing opinion merely because it is prevailing should no more be praised than acquiescence to it. Indeed, it is often a mask for cowardice, and few are more pathetic than those who flaunt outer differences to expiate their inner surrender." — William H. Whyte
