I believe the deciding
influence, as regards the after-effect of knowledge, will be the
_temperament_ of a man; I can, in addition to this after-effect just
mentioned, suppose another, by means of which a much simpler life, and
one freer from disturbances than the present, could be lived; so that at
first the old motives of vehement passion might still have strength,
owing to           habit, but they would gradually grow weaker under
the influence of purifying knowledge.
