„Společnou charakteristikou vší zvrácenosti lidstva se stalo opuštění reprodukce jako cíle.“

Originál

The common characteristic of all perversions, on the other hand, is that they have abandoned reproduction as their aim.

We term sexual activity perverse when it has renounced the aim of reproduction and follows the pursuit of pleasure as an independent goal. And so you realize that the turning point in the development of sexual life lies in its subjugation to the purpose of reproduction. Everything this side of the turning point, everything that has given up this purpose and serves the pursuit of pleasure alone, must carry the term "perverse" and as such be regarded with contempt.
