Our species is the only creative species, and it has only one creative instrument, the individual mind and spirit of a man. Nothing was ever created by two men. There are no good collaborations, whether in music, in art, in poetry, in mathematics, in philosophy. Once the miracle of creation has taken place, the group can build and extend it, but the group never invents anything. The preciousness lies in the lonely mind of a man.

To illustrate the difference between the innovator and the dull crowd of routinists who cannot even imagine that any improvement is possible, we need only refer to a passage in Engel's most famous book. Here, in 1878, Engels apodictically announced that military weapons are "now so perfected that no further progress of any revolutionizing influence is any longer possible." Henceforth "all further [technological] progress is by and large indifferent for land warfare. The age of evolution is in this regard essentially closed." This complacent conclusion shows in what the achievement of the innovator consists: he accomplishes what other people believe to be unthinkable and unfeasible.

Responsibility and danger do not tend to free or stimulate the average person's mind- rather the contrary; but wherever they do liberate an individual's judgement and confidence we can be sure that we are in the presence of exceptional ability.
