Mathematical economics has made immense technical progress in
the last twenty years. Unfortunately, it has to a too large extent
remained isolated within the larger historical context of economic
debate, somehow ignoring rather than clarifying the great issues
around which this debate has raged; like a delicate precision clock-
work which the economist admires, as in a jeweler's window, before
setting back to serious work with pick and shovel. For this reason
I have tried, in the lectures from which the present volume is taken,
to direct attention particularly to these issues, and have attempted
to put economics in the foreground and mathematics together with
mathematical rigor in the background-although, alas, mathematics
in doing its good services has a way of calling attention to itself.
Where perfect generality has meant relative vagueness of results,
while reasonable assumptions have led to suggestive conclusions,
I have, in consequence, preferred to make rather than to omit these
assumptions.
