Three Contributions to the Theory of Sex by Sigmund Freud

First published in the year 1905, the present book, ‘Three Contributions to the Theory of Sex’ by the father of psychoanalysis Sigmund Freud, advanced his theory of sexuality, in particular its relation to childhood. Freud began his first essay, on “The Sexual Aberrations”, by distinguishing between the sexual object and the sexual aim — noting that deviations from the norm could occur with respect to both. The sexual object is therein defined as a desired object, and the sexual aim as what acts are desired with said object.
