put at his disposal, let us disguise the fact as we may, the services of a number of other men who will work in accordance with his orders. This, as we have seen already, is what is done by the ordinary investor whenever he lends capital to an inventor. He supplies him with the food by which the requisite subordinates must be fed; and the state, were the state the capitalist, would do virtually the same thing. It could give him his opportunity in no other way. Further, if the invention in question turns out to be successful--here is another point which has already been explained and emphasised--the wage-capital which has been consumed by the labourers is replaced by some productive implement, which is more than the equivalent of the labour force spent in constructing it. If, on the other hand, the invention turns out to be a failure, the wage-capital is wasted, and, so far as the general welfare is concerned, the state might just as well have thrown the whole of it into the sea. Since, then, the opportunities which the state would have at its disposal, would consist at any moment of a given amount of capital, and since any portion of this which was used unsuccessfully would be lost, the number of opportunities which the state could allocate to individuals would be limited, and each opportunity which was wasted by one man would diminish the number that could be placed at the disposal of others. Now, any one who knows anything of human nature and actual life knows this--that the number of men who firmly and passionately believe in the value of their own inventions, or other industrial projects, is far in excess of those whose ideas and projects have actually any value whatsoever. When the _Great Eastern_, the largest ship of its time, had been built on the Thames by the celebrated engineer Brunel, its launching was attended with unforeseen and what seemed to be insuperable difficulties. Mr. Brunel's descendants have, I believe, still in their possession, a collection of drawings, sent him by a variety of inventors, and representing all sorts of devices by which the launching might be accomplished. All were, as the draughtsmanship was enough to show, the work of men of high technical training; but the practical suggestions embodied in one and all of them could not have been more grotesque had they emanated from a home for madmen. To have given an equality of opportunity to all this tribe of inventors of putting their devices to the test would have probably cost more than the building of the ship itself, and the ship at the end would have been stranded in the dock still. This curious case is representative, and is sufficiently illustrative of the fact that opportunity of this costly kind could be conceded to a few only of those who would demand, and believe themselves to deserve it; and the state, as the trustee of the public, would have, unless it were prepared to ruin the nation, to be incomparably more cautious than any private investor.[28]
