The Basis of Memory

Originally published in 1928 this short essay looks two rival theories of the time, both hypothetical, and explores which one ‘better fits the facts’.
Whether memory depends on "enduring traces" in brain structure (to use the language of Professor Semon), or whether it depends on records in "psychical structure" (to use the language of Professor McDougall).
Today it can be read and enjoyed in its historical context.
