Note 198b — ON CYCLES. (chapter xi. of unconscious memory.)
Reading edition
Mr. Herbert Spencer denies that there can be memory without a “tolerably deliberate succession of psychical states.” [198c] So that practically he denies that there can be any such thing as “unconscious memory.” Nevertheless a few pages later on he says that “conscious memory passes into unconscious or organic memory.” [198d] It is plain, therefore, that he could after all find no expression better suited for his purpose.
