"The idea that man is essentially a product of his environment is an almost essential part of the folklore of Western half-education." - Erik von Kuehnelt-Leddihn
That would be Eric von Kuehnelt-Leddihn's Leftism Revisited. I have one of the original copies, and until it was reprinted what copies were available cost $80.
It is a truly profound work, and is EvKL's magnun opus. I can't tell you how much it has influenced me.
The late William F. Buckley wrote the introduction to it, and said it was "like going to graduate school again."
Where to start?
EvKL said leftism is about "the overthrow of the Father," and he's right. It's not just "feminism" that wants to overthrow the Father, but all leftists.
Just as bad, they think people are purely products of their environment, so they want to destroy society, since in their delusions they think they can rebuild it from the ground up and make people into gods. And they always try it through the deaths of millions and the destruction of everything.
He claimed the Nazis were overwhelming leftist, and once you read the book he realize he's right.
And who does he believe is the founder of modern-day leftism? The Marquis de Sade. And he makes a very good case for it, too.
Sade, who believed people were no better than insects, was a materialist atheist. All those things go together, even today, with "leftist libertarians," who are not libertarians but just plain leftists, and just as dangerous.
EvKL believed in natural hierarchies, he believed in religion and realized its destruction would lead to genocide, and he did not believe in equality, because to be equal you have to be identical, the way two dimes or nickels are identical. And that can be done only through force - through death and destruction.
And he certainly did not believe in democracy, which he considered a horror. He also considered it "antique." And that is was based on envy.
What he believed in, instead, was mature constitutional monarchies.
I'll stop here, since I could go on for a long time. All I can add is this: buy the book. I guarantee that you will not be disappointed.
“The farmer was and remains the stumbling block to socialist experiments everywhere. Since he raises his own food and tends to live in his own house, he is less 'controllable' than say, the urban dweller.” - Erik von Kuehnelt-Leddihn
