Abstract
Many, including some celebrated liberal theorists, defend liberty on empirical, prudential, utilitarian grounds such that if practical considerations or changed circumstances were to make intolerance more useful than tolerance, they would be committed to a policy of intolerance. Their theories are therefore liberal only contingently. They cannot be denied the title "liberal," for, apart from historical usage, a theory is liberal if it proceeds on the basis of a high evaluation of liberty whether or not the evaluation rests purely on contingent facts. Other liberals defend liberty for its own sake as well as for its utility, and argue that the sole function of the state consists in preserving or promoting liberty. Other theorists stress liberty as the supreme good but take note of the relevance and importance of other goods, e.g., happiness, justice, well-being, fraternity. They too, because of their stress on liberty, and because they include some of the most celebrated exponents of liberalism, must be included as liberals.
