This is a follow-up post of my previous post on Perspectives and Co-ordinate geometry. Each individual's perspectives form the different axes on which the individual perceives the world - and judges the world, so you have (happiness-sorrow axis, good-bad axis, moral-immoral axis, ethical-unethical axis, and so on). Each of these axes define who you are, your values, your beliefs, et al. If I were to map each of these axes against the society's axes, then we can plot an individual on the society space (its an n-dimensional space, mind you).
Now, get this. The origin of the society (the norms dictated by the society) represented by (0,0,..,0) would be at a certain distance from your own origin say (1,2,1,-4,...,3). The vector (going outwards from the origin) which connects your origin to the society's origin is your vector of existence. Every individual has his vector of existence. The people who are afraid of society and peer pressure have their origins closest to the society's origins. Carefree people tend to be away from that origin. The more deviant you are to the society, the further you would be from the origin.
What makes a society? You, me and everybody. Thus, the society is a summation of these vector misalignments. And that my friend defines the origin of the society. Over a period of time, the origin naturally shifts - it shifts because many people change their origins (values, beliefs, etc), thus ensuring that the society also goes through that same shift (although much more gradually). A fact that would have been a taboo for the society would be a norm today. Take mini-skirts for instance or gay rights. Society changes its norms, because the collective changes their norms. The origin has shifted!!
