Praxis is an interesting choice of word here, originating from greek it means practice but not in the common English usage denoting primarily repition but rather its root context of meaning real or practical, the alternative end of theory being the common use case. This makes its usage here interesting as here it is used to denote the making of the theoritical on these topics into praxis or doctrine that is workable. That is an interesting denotion but it is also one that requires the reader to know what praxis means for it to make sense to them which given the generally academic but intelligable to the average reader nature of most of this work the use of such an obscure term for most is a curious choice in this context.
