(Chapter V.—The Method of Political Reasoning, page 138)

The method of political reasoning has shared the traditional over-simplification of its subject-matter.

In Economics, where both method and subject-matter were originally still more completely simplified, 'quantitative' methods have since Jevons's time tended to take the place of 'qualitative'. How far is a similar change possible in politics?

Some political questions can obviously be argued quantitatively. Others are less obviously quantitative. But even on the most complex political issues experienced and responsible statesmen do in fact think quantitatively, although the methods by which they reach their results are often unconscious.

When, however, all politicians start with intellectualist assumptions, though some half-consciously acquire quantitative habits of thought, many desert politics altogether from disillusionment and disgust. What is wanted in the training of a statesman is the fully conscious formulation and acceptance of those methods which will not have to be unlearned.

Such a conscious change is already taking place in the work of Royal Commissions, International Congresses, and other bodies and persons who have to arrange and draw conclusions from large masses of specially collected evidence. Their methods and vocabulary, even when not numerical, are nowadays in large part quantitative.

In parliamentary oratory, however, the old tradition of over-simplification is apt to persist.
