It is interesting to compare this account of Happiness with Mill’s in _Utilitarianism_. Mill’s is much the less consistent: at times he distinguishes and at times he identifies, happiness, pleasure, contentment, and satisfaction. He wavers between belief in its general attainability and an absence of hopefulness. He mixes up in an arbitrary way such ingredients as “not expecting more from life than it is capable of bestowing,” “mental cultivation,” “improved laws,” etc., and in fact leaves the whole conception vague, blurred, and uncertain. Aristotle draws the outline with a firmer hand and presents a more definite ideal. He allows for the influence on happiness of conditions only partly, if at all, within the control of man, but he clearly makes the man positive determinant of man’s happiness he in himself, and more particularly in what he makes directly of his own nature, and so indirectly of his circumstances. “‘Tis in ourselves that we are thus or thus” But once more this does not involve an artificial or abstract isolation of the individual moral agent from his relation to other persons or things from his context in society and nature, nor ignore the relative dependence of his life upon a favourable environment. The main factor which determines success or failure in human life is the acquisition of certain powers, for Happiness is just the exercise or putting forth of these in actual living, everything else is secondary and subordinate. These powers arise from the due development of certain natural aptitudes which belong (in various degrees) to human nature as such and therefore to all normal human beings. In their developed form they are known as virtues (the Greek means simply “goodnesses,” “perfections,” “excellences,” or “fitnesses”), some of them are physical, but others are psychical, and among the latter some, and these distinctively or peculiarly human, are “rational,” _i e_, presuppose the possession and exercise of mind or intelligence. These last fall into two groups, which Aristotle distinguishes as Goodnesses of Intellect and Goodnesses of Character. They have in common that they all excite in us admiration and praise of their possessors, and that they are not natural endowments, but acquired characteristics But they differ in important ways. (1) the former are excellences or developed powers of the reason as such—of that in us which sees and formulates laws, rules, regularities systems, and is content in the vision of them, while the latter involve a submission or obedience to such rules of something in us which is in itself capricious and irregular, but capable of regulation, viz our instincts and feelings, (2) the former are acquired by study and instruction, the latter by discipline. The latter constitute “character,” each of them as a “moral virtue” (literally “a goodness of character”), and upon them primarily depends the realisation of happiness. This is the case at least for the great
