Robert Axelrod az Amerikai Politikatudományi Társaság elnökeként elmondott tavalyi beszédét egy kedves történettel kezdte, amely ráadásul érdekes adalék arra vonatkozólag, hogy mennyit tudnak meríteni egymástól még látszólag egymástól távol eső tudományágak is.

“Let me begin with my favorite story about imports. It
starts with Darwin who describes how he imported a key
insight from Malthus, who was a political economist. Darwin
had spent years collecting his data. Then, as he wrote
in his autobiography:”

“Fifteen months after I had begun my systematic enquiry, I happened
to read for amusement Malthus on Population and being
well prepared to appreciate the struggle for existence which goes
on everywhere . . . it at once struck me that under these circumstances
favorable variations would tend to be preserved, and
unfavorable ones to be destroyed. The result of this would be the
formation of a new species. Here, then, I had at last got a theory
by which to work”

“The really neat thing is that twenty years later, another
political economist, namely Marx, imported Darwin’s conception
of struggle back into political economy. As Marx
wrote in a letter to a colleague:”

“Darwin’s book is very
important and serves me as the basis in natural sciences
for the class struggle in history.”
