Schelling’s Freiheitschrift ‘freedom essays’ touches on evil in deep and I’d say, rather unconventional ways. He elevates evil to a status, unlike any philosopher before him in the western canon. While, evil, is not ‘the answer’ for him. It’s a part of the equation that in the least must be accounted for, if not incorporated into, the very idea of freedom itself. This work isn’t what I would call a ‘philosophy of life’, however, because the question of evil having absolute importance to the possibility of freedom in his eyes, then it might qualify. Although, as a warning, this work is enormously complicated and obscure. From the scale of the book, being, I don’t know, 60-75 pages? It’s probably the most dense book I’ve come across.
