MEANING AND USE OF STUDY OF HISTORY 291
ated by, or rather consists in, the ceaseless transforma-
tion of the ideas determining human action. Among
these ideological changes those concerning the specific
historical understanding of the past play a conspicuous
role. What distinguishes a later from an earlier age is,
among other ideological changes, also the change in
the understanding of the preceding ages. Continu-
ously examining and reshaping our historical under-
standing, the historians contribute their share to what
is called the spirit of the age.

Falsifying History
Because history is not a useless pastime but a study
of the utmost practical importance, people have been
eager to falsify historical evidence and to misrepresent
the course of events. The endeavors to mislead posterity
about what really happened and to substitute a fabri-
cation for a faithful recording are often inaugurated by
the men who themselves played an active role in the
events, and begin with the instant of their happening,

Sometimes historical research succeeds in unmasking inveterate
errors and substituting a correct account of events for an inadequate
record even in fields that had up to then been considered fully and
satisfactorily explored and described. An outstanding example is the
startling discoveries concerning the history of the Roman emperors
Maxentius, Licinius, and Constantinus and the events that ended the
persecution of the Christians and paved the way for the victory of the
Christian Church. (See Henri Gregoire, Les Persecutions dans VEm-
pire Romain in Memoires de l'Academie Royale de Belgique, Tome 46,
Fascicule 1, 1951, especially pp. 79-89, 153-6.) But fundamental
changes in the historical understanding of events are more often
brought about without any or only slight revision of the description
of external events.
