Sacher-Masoch is the vanguard for civilisation, he contributes to progressive spiritual evolution in several aspects.
But his conclusion is not such a contribution.
That woman, as nature has created her, and man at present is educating her, is man’s enemy. She can only be his slave or his despot, but never his companion. This she can become only when she has the same rights as he and is his equal in education and work.
The same rights as he?! Really?
The last sentence is remarkably schoolboyish for the man who gave is S&M. It’s an idealism that turns away from our biological nature, our true nature, grounding any such idle speculation. He should have stopped himself short: she can be his slave or despot, not because of (or despite of) progressive trajectory, some Chardanian omega point … She’s that way because she loves to be that way.
And that’s the way she’s progressed: feminism intertwined with DnA embodiment of the S&M fetish.
