You don't need to be, though I'm sure it helps, an Orthodox Christian to see that this is an incredibly lucid and perspicacious exploration and refutation of Nihilism, the pervasive spirit of our age and the cause of worldly incoherence.
Fr. Seraphim comes from a position of faith and clarity of argument that manages to be like a dagger which slices through counter-arguments, but, which also harbors a fundamental fairness and openess to acknowledge the appeal and positives that have driven Nihilism and its different breeding grounds (such as Liberalism, Realism and Vitalism).
I found the section on vitalism most engaging in terms of considering his words, and hypothesizing about what his reaction would've been, in this current context where the things he describes have been so amplified. His arguments that critique have now become apologies, justifying rather than improving bad art, especially hit home.
He diagnoses a fundamental, driving, restlessness in current man and skewers the relativistic, hubristic, Superhuman/God-man status that has unmoored society from any norms or truth and urges the inevitable nihilism of destruction, its own logical end. He does this showing his own expertise in the thoughts of men like Hitler, Nietzsche, Bakunin, and Dostoevsky, presenting their beliefs, ideals, or warnings/insights for the organisation of humanity and society.
… its Nihilist counterpart is full of doubt, suspicion, disgust, envy, jealousy, pride, impatience, rebelliousness, blasphemy - one or more of these qualities predominating in any given personality. It is an attitude of dissatisfaction with self, with the world, with society, with God; it knows but one thing: that it will not accept things as they are , but most devote its energies either to changing them or fleeing from them.
The book is slight and rounds out with an essay about the philosophy of the absurd which picks at the same strand the essay on nihilism deals with, pointing out how a rejection of absolute truth, or a belief in ultimate meaninglessness, are in themselves claims of absolute truths. They negate themselves from their start, "to assert that 'there is no truth', one must believe in the truth of this statement, and so again affirm what one denies"
Though the connection between the works of nihilism, tracking the ideas of the belief in the Superhuman, the Man-God or man's free will as ruling force without any anchor in truth, to the "Ye shall be as gods" promise of Satan in Genesis, may be a bit of an eye-roll moment for some, I would suggest that - from a believers point of view - this is actually a very coherent and cogent conclusion.
All in all, I think there are a lot of things to mull over in this slender book, it packs quite the punch. Regardless of your status as a believer or not, I would recommend people to read it. One does not have to agree with everything an author says to derive knowledge and valuable nuance from a text, after all. It is a very interesting analysis of the current Century and where, especially, Nietzsche's philosophy has led us, total wars and all, and where it might be heading now. Basically, it'll be worth the while even if it only pisses you off.
I liked it quite a lot and will definitely re-read it and consider some of the finer points. I wish the layout of the book was better though, the text comes across as needlessly dense in this edition. But it is inexpensive, so that's a big plus.
"The philosophy of the absurd is, indeed, nothing oiginal in itself; it is entirely negation, and its character is determined, absolutely and entirely, by that which it attempts to negate."
