We are, perhaps, rather dimly aware of the immense power of our social environment. We seldom realize, for example, that our most private thoughts and emotions are not actually our own. For we think in terms of languages and images which we did not invent, but which were given to us by our society. We copy emotional reactions from our parents, learning from them that excrement is supposed to have a disgusting smell and that vomiting is supposed to be an unpleasant sensation. The dread of death is also learned from their anxieties about sickness and from their attitudes to funerals and corpses.
