Im-mor-al
-adjective
1. violating moral principles; not conforming to the patterns of conduct usually accepted or established as consistent with principles of personal and social ethics.
Well, if you're going to play it that way, then take a gander at this definition of
morality as put forth by the Stanford Encyclopedia of Philosophy:
The term “morality” can be used either
descriptively to refer to some codes of conduct put forward by a society or,
some other group, such as a religion, or
accepted by an individual for her own behavior or
normatively to refer to a code of conduct that, given specified conditions, would be put forward by all rational persons.
Morality is generally shaped by culture, culture is shaped by whoever has literal or figurative power. Generally speaking, in non capitalistic societies, culture is shaped by the desire of the people, what allows society to function most efficiently. Bring money/control into the picture, and those who have the power define culture.
Monogamy, and particularly the value placed on female virginity, arose out of the cultural shift caused by the spread of monotheistic, paternalistic religion that changed women from equal partners to property. Paternity became important with the concept of inheritance of wealth. Pure monogamy/abstinence was generally uncommon in indigenous societies before Christianity polluted them and destroyed their spirituality, which shaped their cultures.
Which is all a roundabout way of saying most of what you
believe is moral is just what you
have been told is moral. Start thinking for yourself and you realize morality is generally subjective.
