Historically our own culture has relied for the creation of rich and contrasting values upon many artificial distinctions, the most striking of which is sex. It will not be by the mere abolition of these distinctions that society will develop patterns in which individual gifts are given place instead of being forced into an ill-fitting mould. If we are to achieve a richer culture, rich in contrasting values, we must recognize the whole gamut of human potentialities, and so weave a less arbitrary social fabric, one in which each diverse human gift will find a fitting place.
