ession like that of the politician. The
profession of the reformer, however, is social, as distinguished from
party politics.

Reform is not revolution. It does not seek to change the mores but
rather to change conditions in conformity with the mores. There have
been revolutionary reformers. Joseph II of Austria and Peter the Great
of Russia were reformers of that type. But revolutionary reforms have
usually failed. They failed lamentably in the case of Joseph II and
produced many very dubious results under Peter.

A revolution is a mass movement which seeks to change the mores by
destroying the existing social order. Great and silent revolutionary
changes have frequently taken place in modern times, but as these
changes were not recognized at the time and were not directly sought by
any party they are not usually called revolutions. They might properly
be called "historical revolutions," since they are not recognized as
revolutions until they are history.

There is probably a definite revolutionary process but it has not been
defined. Le Bon's book on the _Psychology of Revolution_, which is the
sequel to his study of _The Crowd_, is, to be sure, an attempt, but the
best that one can say of it is that it is suggestive. Many attempts have
been made to describe the processes of revolution as part of the whole
historical process. This literature will be considered in the chapter on
"Progress."
