International law has survived astonishingly well the host of ingenious horoscopes cast regarding its future by magi in many lands. Some have been prophets of gloom and have prognosticated its impending breakdown. Others have purported to see a constellation of circumstances which promised an unexpectedly bright future for the weakling in the laws family. Yet when, at times, such astrologers appear in groups, it is not sufficient to explain their emergence in terms of individual psychology; for, like the phenomenon which they analyze, they themselves are very much the product of their environment. Allowing for exceptional types, they fall into two categories which are fairly closely related to the cycles of pre- and post-war periods. For the sake of brevity, and without disrespect, they may be named the “pre-war” and “post-war” schools.
