It
must
, however
, be
remembered
that
no
methodology
of Political
Science
can
lead
to
true conclusions , unless we take human nature into account . After all the State exists for man and it endeavours to cater to his needs in order to make his life happy. Man is the central subject of our study and we must go to his psychology to find out the really correct solution of his problems. Hitherto political thinkers had regarded man as a rational being and accepted this nature of man as a dogmatic truth and consequently the starting point of their investigations. Recently, Graham Wallas, in his book Human Nature in Politics, has revolted against this traditional assumption of human nature. Man according to Graham Wallas, is hardly rational in his behavior.
