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."

The difference, therefore, does not operate in every sense, but it does in most of them. Even the most civilized peoples, in short, can be fired with passionate hatred for each other.

Most people can't think, most of the remainder won't think, the small fraction who do think mostly can't do it very well. The extremely tiny fraction who think regularly, accurately, creatively, and without self-delusion- in the long run, these are the only people who count.
