The idealism of Plato is founded upon this sentiment. He would maintain that in some sense or other truth and right are alone to be sought, and that all other goods are only desirable as means towards these. He is thought to have erred in ‘considering the agent only, and making no reference to the happiness of others, as affected by him.’ But the happiness of others or of mankind, if regarded as an end, is really quite as ideal and almost as paradoxical to the common understanding as Plato’s conception of happiness. For the greatest happiness of the greatest number may mean also the greatest pain of the individual which will procure the greatest pleasure of the greatest number. Ideas of utility, like those of duty and right, may be pushed to unpleasant consequences. Nor can Plato in the Gorgias be deemed purely self-regarding, considering that Socrates expressly mentions the duty of imparting the truth when discovered to others. Nor must we forget that the side of ethics which regards others is by the ancients merged in politics. Both in Plato and Aristotle, as well as in the Stoics, the social principle, though taking another form, is really far more prominent than in most modern treatises on ethics. The idealizing of suffering is one of the conceptions which have exercised the greatest influence on mankind. Into the theological import of this, or into the consideration of the errors to which the idea may have given rise, we need not now enter. All will agree that the ideal of the Divine Sufferer, whose words the world would not receive, the man of sorrows of whom the Hebrew prophets spoke, has sunk deep into the heart of the human race. It is a similar picture of suffering goodness which Plato desires to pourtray, not without an allusion to the fate of his master Socrates. He is convinced that, somehow or other, such an one must be happy in life or after death. In the Republic, he endeavours to show that his happiness would be assured here in a well-ordered state. But in the actual condition of human things the wise and good are weak and miserable; such an one is like a man fallen among wild beasts, exposed to every sort of wrong and obloquy.
