According to both schools, the importance of causal efficacy, and of action exemplifying its presupposition, should be mainly characteristic of high-grade organisms in their best moments. Now if we confine attention to long-range identification of cause and effect, depending on complex reasoning, undoubtedly such high-grade mentality and such precise determination of sense-data are required.

We must consider the immediate present in its relationship to the immediate past. The overwhelming conformation of fact, in present action, to antecedent settled fact is to be found here.
My point is that this conformation of present fact to immediate past is more prominent both in
