The first corner of the triangle is affinity. The basic definition of affinity is the consideration of distance, whether good or bad. The most basic function of complete affinity would be the ability to occupy the same space as something else. The word affinity is here used to mean love, liking or any other emotional attitude. Affinity is conceived in Scientology to be something of many facets.
Affinity is a variable quality.
Man would not be man without affinity. Every animal has affinity to some degree, but man is capable of feeling an especially large amount. Long before he organized into cities, he had organized into tribes and clans. Before the tribes and clans there were undoubtedly packs. Man's instinctive need for affinity with his fellow human beings has long been recognized, and his domestication of other animals shows that this affinity extends also to other species.
