they assume. In this sense sexual selection is no longer a hypothesis
concerning the truth of which it is possible to dispute; it is a
self-evident fact. The difficulty is not as to its existence, but as to
the methods by which it may be most precisely measured. It is
fundamentally a psychological process, and should be approached from the
psychological side. This is the reason for dealing with it here. Obscure
as the psychological aspects of sexual selection still remain, they are
full of fascination, for they reveal to us the more intimate sides of
human evolution, of the process whereby man is molded into the shapes we
know.
