For, human jealousy has universally been considered a negative emotion.

For, human jealousy has universally been considered a negative emotion. Has an exception been made in favour of jealousy so as to safeguard husband- wife relationship? If so, why? If there are other reasons for men protecting the honour of their women, as if it were a question of their own honour, how can these be explained?

Likewise, the desires and social norms favouring clothing or covering of female body, curbing sexual promiscuity, prohibiting marriage between persons too closely related and similar other moral and legal restraints need be explained. Their examination can be in terms of whether or not they have their roots in the human nature, physiological and psychological.

Then, one may as well ask as to whether or not sexual morals are linked to the natural requirements of gregarious living Or, is it part of their inborn tendencies, feelings and concerns towards an appropriate human survival in the natural process. Or, is there any possibility that historical causes, other than natural, have gradually affected and influenced human conscientiousness and behaviour?

If the source of human morality has been entirely rooted in nature, it is hard to explain how not only the ancient savages, but today's isolated primitive tribes, living in the manner of their ancestors, were and are quite unlike the civilized people. The origins and raison d'etre of sexual morality may be diverse. So can be the historical conditions of social evolution, with reference to human sexual ethics in particular.

Nevertheless, the question relevant to us now is as to whether or not the traditional morals are valid in the modern conditions towards achieving overall human progress. Specifically, we must ask ourselves whether or not we must now safeguard the traditional sexual ethics or replace them by instituting new morals. Will Durant does not trace human sexual morality to any origins in the mother nature.

He attributes moral evolution to reasons arising from historical experience, even some occasionally unhappy or cruel happenings in the past. He favours retaining the substance of traditional morals, while allowing continued evolution of the forms, in order to selectively practise the best without shortcomings.

Referring to morals concerning female virginity, modesty and bashfulness, Will Durant observes to the effect that traditional values and customs evidence a natural process of moral selection, involving trials and errors through centuries.
