Is Thelema a philosophy?
Yes, the fundamental postulates of that philosophy being the non-existence of objective moral qualities of any kind, and the natural conclusion that the “proper” course of action for any given individual is therefore that course of action which is most natural to him, as opposed to an alternative course of action which is mandated by some artificial and imaginary standard. Accordingly, the primary task of the aspiring Thelemite is to thoroughly investigate the nature of his self – and, by necessity, of his environment – in order that he may identify and remove the arbitrary restrictions which prevent him from both determining what this “most natural course” actually is and from executing it.
