There is the reproduction of an idea which has been produced once
already, and there is the reproduction of a living form which has been
produced once already. The first reproduction is certainly an effort of
memory. It should not therefore surprise us if the second reproduction
should turn out to be an effort of memory also. Indeed all forms of
reproduction that we can follow are based directly or indirectly upon
memory. It is only the one great act of reproduction that we cannot
follow which we disconnect from memory.
