Many things may be copied by the latter; the example as such also acts upon them; and many achievements directly serve other branches too [...]. - Joseph Schumpeter

The swarm-like appearance of new combinations easily and necessarily explains the fundamental features of periods of boom.

In all cases, not only in the two which we have analyzed, recovery came of itself. There is certainly this much of truth in the talk about the recuperative powers of our industrial system. But this is not all: our analysis leads us to believe that recovery is sound only if it does come of itself. For any revival which is merely due to artificial stimulus leaves part of the work of depressions undone and adds, to an undigested remnant of maladjustment, new maladjustment of its own which has to be liquidated in turn, thus threatening business with another crisis ahead. Particularly, our story provides a presumption against remedial measures which work through money and credit. For the trouble is fundamentally not with money and credit, and policies of this class are particularly apt to keep up, and add to, maladjustment, and to produce additional trouble in the future.

When we inquire about the general forms of economic phenomena, about their uniformities, or about a key to understanding them, we ipso facto indicate that we wish at that moment to consider them as something to be investigated, to be sought for, as the “unknown”; and that we wish to trace them to the relatively “known,” just as any science deals with its object of inquiry.
