From Self-Development and the Way to Power, by L. W. Rogers (7)

Every human being must make, and is making, this long evolutionary
journey from spiritual infancy to godlike power and perfection, but
there are two ways in which it may be done. We may, as the vast
majority do, accept the process of unconscious evolution and submit to
nature's whip and spur that continuously urge the thoughtless and
indifferent forward until they finally reach the goal. Or, we may
choose conscious evolution and work intelligently with nature, thus
making progress that is comparatively of enormous rapidity and at the
same time avoid much of what Hamlet called the "slings and arrows of
outrageous fortune."
