Values differ among human societies and even among human individuals, even within the same human population or human social group; and human values change through time, that is, not only in the scale of human evolution (hundreds of thousands or millions of years), but in the scale of human history (hundreds or thousands of years), and even in the scale of a human life (tens of years).	cache/expositions-1797.pdf	txt/expositions-1797.txt
