We can easily invent hypotheses, which are quite likely to be true, as to connections in the brain caused by past experience, and themselves causing the different response.
No doubt physiology, especially the disturbances of memory through lesions in the brain, affords grounds for this hypothesis; nevertheless it does remain a hypothesis, the validity of which will be discussed at the end of this lecture.
If, then, there is to be some standing difference between the person who can remember a certain fact and the person who cannot, that standing difference must be, not in anything mental, but in the brain.
If there are to be purely psychological causal laws, taking no account of the brain and the rest of the body, they will have to be of the form, not "X now causes Y now," but--
They are explained without it by Semon's "engram," or by any theory which regards the results of experience as embodied in modifications of the brain and nerves.

He approached the group slowly, but with composure; but he was decidedly pale, and the eyes of Brain and Fisher had already taken in one detail of the green-clad figure more clearly than all the rest.
Rather to the surprise of the company, Brain did not follow up the question thus suggested; but, while retaining an air of leading the inquiry, had also an appearance of changing the subject.
The Malay was thinking fast, and could von Horn have guessed what thoughts raced through the tortuous channels of that semi-barbarous brain he would have wished himself safely housed in the American prison where he belonged.
Can it be possible that, after all, his brain is defective?
It is possible that the hard study and close confinement to that little building have been too severe upon his brain and nerves.
