Vocation presupposes harmony between social structure and individual impulses. [definitional]
For such a thing as vocation to be possible, there must exist that harmony, whatever its origin, between the structure and development of society, and individual qualities and impulses. It is this general premise that constitutes the ultimate basis of the idea that for every personality there exist a position and a function in society to which he is called and which he must seek and find.
