'The apparent assumption throughout psychoanalytic writing and practice is that the real sexual fact is physical copulation. Everything else is taken actually for ersatz whether as a defensive substitute or as a socially valuable but nevertheless sexually denatured sublimation.' On this premise, the author discusses what he sees as weaknesses and discrepancies in the freudian libido theory. He explores the metapsychology of meaning, symbol, actuality, masculinity, femininity, and other concepts.
