The Note-Books of Samuel Butler

Memory is a kind of way (or weight—­whichever it should be) that the mind has got upon it, in virtue of which the sensation excited endures a little longer than the cause which excited it.  There is thus induced a state of things in which mental images, and even physical sensations (if there can be such a thing as a physical sensation) exist by virtue of association, though the conditions which originally called them into existence no longer continue.

This is as the echo continuing to reverberate after the sound has ceased.

To be is to think and to be thinkable.  To live is to continue thinking and to remember having done so.  Memory is to mind as viscosity is to protoplasm, it gives a tenacity to thought—­a kind of pied a terre from which it can, and without which it could not, advance.

Thought, in fact, and memory seem inseparable; no thought, no memory; and no memory, no thought.  And, as conscious thought and conscious memory are functions one of another, so also are unconscious thought and unconscious memory.  Memory is, as it were, the body of thought, and it is through memory that body and mind are linked together in rhythm or vibration; for body is such as it is by reason of the characteristics of the vibrations that are going on in it, and memory is only due to the fact that the vibrations are of such characteristics as to catch on to and be caught on to by other vibrations that flow into them from without—­no catch, no memory.
