But this is really a simple analysis of the party division. A party is a synthesis of various interests. It is as much the result of mental traits of men as they are of the interests near to their heart, of the conditions and surroundings in which they live and of the social structure of which they are the members.
Bryce beautifully sums up when he says that “though the professed reason for the existence of a party is the position of a particular set of doctrines, it has a concrete side as well as a set of abstract doctrines.
It is abstract in so far as it represents the adhesion of many minds to the same opinions. It is concrete as consisting of a number of men who act together in respect of their holding or professing to hold such opinions.”
