The Human Sciences. The decreased urgency of the
problem on the physical side in the present century
has been balanced by increased pressure from histori-
cal, social, and psychological science. However little
capable these sciences may be of attaining the mathe-
matical rigor pursued in physical enquiry, they disclose
a deep and complex conditioning of the individual by
background, environment, and subconscious makeup,
such as threatens to reduce the exercise of genuine
choice to trivial proportions. Several thinkers have
been impressed by the predominant effect of one factor
or another: Marx by the pressure of economic needs
and of the current system for coping with them; Freud
by the twists of emotional attitude formed in us during
one helpless immaturity; Jung by the individual's in-
heritance of ancestral archetypes of personal relation
or function.
