Which only means that intentional self-caused progress and regress are natural processes. Exactly as expected. Nothing unnatural anywhere. You just have to be consistent when applying logic and categories. Both, humanism and Christianity, are perfectly natural as they are logical consequences of particular choices.

It's so obvious that it even does not warrant a serious discourse. After all, if that was not the case we would not have the existential perils of libertarian freedom of choice from limited set of options in the face of uncertainty introduced by trying to predict which deterministic consequences, all of them of fatalistic proportions, are tied to which causal options.

Alas, how do you expect to make a truly informed choice without solving ontology first? And how do you expect to know ontic facts, when you believe in arbitrary preconceptions you acquired, and which are overlaid on top of them? In other words, why do you insist that I am a departure from nature? Man, with all my creativity, intellect, instincts, or cravings, with all social interactions and technology, all the way to the bottom of reality -- I'm as natural as it gets. Quite naturally :P
