Incest, which is the gravest wrong, consists in unifying what
is one to begin with by the device for unifying opposites, and of failing to separate
what was one into two, thereby directly inverting in one stroke both sides of
the formula, that only different things can be united by sexual intercourse and
only united things made different.
The symbol of love bridges these two different elements.
It is love which preserves the unity of the differentiated and further differentiating
parents and their children as well as the child from his siblings. The one is
conjugal love, marked by an erotic component; the other is cognatic love, wholly
without erotic aspects; but both are love which is unifying. And love is what
American kinship is all about. (1968:40)
