The history of all hitherto existing society(2) is the history of class struggles.
Freeman and slave, patrician and plebeian, lord and serf, guild-master(3) and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary reconstitution of society at large, or in the common ruin of the contending classes.
In the earlier epochs of history, we find almost everywhere a complicated arrangement of society into various orders, a manifold gradation of social rank. In ancient Rome we have patricians, knights, plebeians, slaves; in the Middle Ages, feudal lords, vassals, guild-masters, journeymen, apprentices, serfs; in almost all of these classes, again, subordinate gradations.
The modern bourgeois society that has sprouted from the ruins of feudal society has not done away with class antagonisms. It has but established new
There is no reason whatsoever that this should be allowed, no matter what part of the world you are in. A 15-year old girl shouldn't be having sex with anyone, let alone a family member. A 47-year old man shouldn't even be contemplating sex with a girl of that age, especially when factoring in that it is his niece. The mere idea is horrifying!
Depends very much on culture and up-bringing. A fourteen years old girl in Germany is considered mature enough to take such decisions (age of consent). In most Anglo-Saxon countries they are brought up to be mature at 16 or 18.
Not much biology is involved. However with the decreasing age of puberty of girls and boys, the age of consent will probably fall in the future, whether we scream or not.
No, a 15-year old girl should not be allowed to have sex with her 47-year old uncle in Germany because she is too young to show consent. Plus, they are related. They should not be allowed to see each other anymore. She should grow up and be able to choose her own husband when she is of age.
To begin with, a 15 year old girl should not be allowed to have sex with a 47-year old man. this can actually be classified as rape simply because the 15 year old is not mature enough to be in sexual contact (not an adult). Lastly, having sex with an uncle is incest and should not be encouraged, its a sin.
