cumulation

So we shall speak of the type of historical cumulation as standing between evolution and bare temporal sequence.

There is a sort of cumulation of consecutive phases, the later ones being impossible without the earlier.

We have called one type of history evolution, the other cumulation; but how have these higher types been reached?

And this process is not less a process of cumulation than any other sort of development or so-called progress in history is.

The smallest cause, by cumulation of its action, can attain the greatest results.
