Abstract
The line of thought from which contemporary Social Science has come forth was occupied with problems of public policy in a way which has since become very much less prominent in the work of social scientists. The classic figures of social thought —Aristotle, Plato, Adam Smith, Montesquieu, Jeremy Bentham, James and John Stuart Mill, Ricardo, Hobbes and Locke, Burke, Machiavelli and Hegel—were all involved in the consideration of the fundmental problems of policy from the point of view of the man who had to exercise power and to make practical decisions. Even where they themselves lived in remoteness from practical affairs the clarification of the standards for the judgment and guidance of public policy was always close to the centre of their attention. The politician's problems, reduced to fundamentals, were their problems. The problem of maintaining order through the prince's exercise of power was the point of departure of classical political philosophy; it was extended by modern liberalism to the maintenance of liberty in a framework of order. Political philosophy was regarded by those who professed it, as a means of enlightening rulers—and citizens—as to the right ends and the approximate means. The great ancestor of modern empirical social research, Sir William Petty, who regarded his task as the quantitative matter-of-fact description of what existed, viewed his problem as set by the prince's need to safeguard and maximise his power. Early economic theory accepted the same task. Even after mercantalism gave way to liberalism, economic theory was still intended to be a guide to policy.
