§ 1. _Mediæval_.

Ingram, in his well-known book on economic history, following the
opinion of Comte, refuses to consider the fourteenth and fifteenth
centuries as part of the Middle Ages.[1] We intend, however, to treat
of economic teaching up to the end of the fifteenth century. The best
modern judges are agreed that the term Middle Ages must not be given
a hard-and-fast meaning, but that it is capable of bearing a very
elastic interpretation. The definition given in the _Catholic
Encyclopædia_ is: 'a term commonly used to designate that period of
European history between the Fall of the Roman Empire and about the
middle of the fifteenth century. The precise dates of the beginning,
culmination, and end of the Middle Ages are more or less arbitrarily
assumed according to the point of view adopted.' The eleventh edition
of the _Encyclopædia Britannica_ contains a similar opinion: 'This
name is commonly given to that period of European history which lies
between what are known as ancient and modern times, and which has
generally been considered as extending from about the middle of the
fifth to about the middle of the fifteenth centuries. The two dates
adopted in old text-books were 476 and 1453, from the setting aside
of the last emperor of the west until the fall of Constantinople. In
reality it is impossible to fix any exact dates for the opening and
close of such a period.'

We are therefore justified in considering the fifteenth century as
comprised hi the Middle Ages. This is especially so in the domain
of economic theory. In actual practice the fourteenth and fifteenth
centuries may have presented the appearance rather of the first stage
