They are brought down into the arena of actual life only when, like souls provided with bodies, they cease to be ideas or toys, and become machines or contrivances manufactured on a commercial basis; and in order to effect successfully this practical transformation, countless processes and countless faculties are involved other than those comprised in intellectual invention itself.
There are cases, no doubt, in which the practical talents necessary for realising an invention and the faculty of invention itself coexist in the same man; but the inventor, when this happens, is not an inventor only.

He is not only a master of ideas; he is a master of things and men.

Such a combination is, however, far from common.

As a rule, if his inventions are to be of any use to the world, the inventor must ally himself with men of another type, and these are the very men whom the author of "The Gospel for To-day" conceives of as simply monopolising and "working for all they are worth" contrivances which would otherwise have been given to the world gratis.

He does not see that, if men such as the steel kings and the oil kings did not work inventions for all they are worth, the inventions themselves would be practically worth nothing.
Let the reader reflect on the astounding ignorance of the world, and especially of the world of industry, which is betrayed with so much naivete by this socialist of the Christian pulpit.
