"In sophisticated circles originality and creativity have always been revered. But it has also been recognized that defining true creativity, in art, science, and other realms, as distinct from more waywardness, has been a fundamental difficulty. The genius and the oddity have too frequently been confused. Because what is newly created is strange, folklore has connected genius with oddity. Any new, successful biological variant - such as a hairless ape - is also strange, but it may be perfectly normal, if by normal we mean healthy and effective."
