Dr. Cunningham draws attention to the fact that the existence of such
a universally received code of economic morality was largely due to
the comparative simplicity of the mediaeval social structure, where
the _relations of persons_ were all important, in comparison with the
modern order, where the _exchange of things_ is the dominant factor.
He further draws attention to the changes which affected the whole
constitution of society in the sixteenth and seventeenth centuries,
and proceeds: 'These changes had a very important bearing on all
questions of commercial morality; so long as economic dealings were
based on a system of personal relationships they all bore an implied
moral character. To supply a bad article was morally wrong, to demand
excessive payment for goods or for labour was extortion, and the
right or wrong of every transaction was easily understood.'[1] The
application of ethics to economic transactions was rendered possible
by the existence of one universally recognised code of morality,
and the presence of one universally accepted moral teacher. 'In the
thirteenth century, the ecclesiastical organisation gave a unity to
the social structure throughout the whole of Western Europe; over the
area in which the Pope was recognised as the spiritual and the Emperor
as the temporal vicar of God, political and racial differences were
relatively unimportant. For economic purposes it is scarcely necessary
to distinguish different countries from one another in the thirteenth
century, for there were fewer barriers to social intercourse
within the limits of Christendom than there are to-day.... Similar
ecclesiastical canons, and similar laws prevailed over large areas,
where very different admixtures of civil and barbaric laws were in
vogue. Christendom, though broken into so many fragments politically,
was one organised society for all the purposes of economic life,
because there was such free intercommunication between its parts.'[2]
'There were three great threads,' we read later in the same book,
'which ran through the whole social system of Christendom. First of
all there was a common religious life, with the powerful weapons of
spiritual censure and excommunication which it placed in the hands of
the clergy, so that they were able to enfo
