ABSTRACT
This chapter investigates immediately only characteristics of actions as material events related to characteristics of the normal or artificially altered anatomy of the brain. The theory of action was treated as a part of the theory of vitalism. The conclusion reached was, that the natural event called 'action' is not susceptible of a physicochemical explanation, and yet is a natural event. Again, a general condition, such as the change of a story from direct to indirect speech, may condition the whole structure of an action. There are two 'criteria' of action as a natural phenomenon which can be adduced with regard to its possibility and to its realization, two characteristics, in fact, which completely govern the subject matter. The purely physical analysis by itself shows that a physico-chemical explanation of the subject matter is impossible. A consequence of orthodox parallelism therefore collapses, and with it parallelism itself.
