A third wrote me a letter bristling with all kinds of challenges, and asked me if I thought, for example, that socialists were such fools as not to recognise that the talents of an inventor like Mr.Edison increased the productivity of labour by the new direction which they gave to it.

I might multiply similar quotations, but one more will be enough here.

It is taken from a long article directed against myself by Mr.Hillquit--a writer to whom my special attention was called as by far the most accomplished exponent, among the militant socialists of America, of socialism in its most logical and most highly developed form.

"It requires," said Mr.Hillquit, "no special genius to demonstrate that all labour is not alike, nor equally productive.

It is still more obvious that common manual labour is impotent to produce the wealth of modern nations--that organisation, direction, and control are essential to productive work in the field of modern production, and are just as much a factor in it as mere physical effort."[3] But we need not confine ourselves to my own late critics in America.
