revelation. Here was something quite different.
He was not out to get people through examina-
tions; that sort of thing did not interest him at
all. Benians quotes one of his opening remarks
to his class: 'If you have come to me for the
knowledge with which to pass the Tripos you
will certainly fail. I know more than you and
I shall defeat you. You had better go else-
where.' ¹ There are many tales that might be
told of him, but I am not here to write a
memorial notice. I tried to do that some thirty
years ago. My purpose now is different. It is
interesting to me and may not be uninteresting
to you to wonder what, if he could return to
earth, Marshall would think of our present
goings-on. What would he have to say about
the current state of economic thought, what of
the current state of fact and policy? I cannot,
of course, discuss this theme thoroughly; only
dip into a few separate bits of it. I shall refer to
six topics only, Mathematical Methods, Statis-
tics, Elasticities, the Rate of Interest, Utilities
and developments towards Socialism; and I
shall never go outside them. Even so it may
perhaps be possible to bring you into brief
contact, more livingly than through books,
with a great Cambridge economist. So much
for apologia. Now for the job itself.
