There are two processes which we adopt consciously or unconsciously when we try to prophesy. We can seek a period in the past whose conditions resemble as closely as possible those of our day, and presume that the sequel to that period will, save for some minor alterations, be similar.

The first is the method the historian; the second that of the scientist. Only the second is open to us now, and this only in a partial sphere.
