7. Human life and conduct are affected by ideals in the same way that

they are affected by the examples of eminent men. Neither the one nor the other are immediately applicable to practice, but there is a virtue flowing from them which tends to raise individuals above the common routine of society or trade, and to elevate States above the mere interests of commerce or the necessities of self-defence. Like the ideals of art they are partly framed by the omission of particulars; they require to be viewed at a certain distance, and are apt to fade away if we attempt to approach them. They gain an imaginary distinctness when embodied in a State or in a system of philosophy, but they still remain the visions of ‘a world unrealized.’ More striking and obvious to the ordinary mind are the examples of great men, who have served their own generation and are remembered in another. Even in our own family circle there may have been some one, a woman, or even a child, in whose face has shone forth a goodness more than human. The ideal then approaches nearer to us, and we fondly cling to it. The ideal of the past, whether of our own past lives or of former states of society, has a singular fascination for the minds of many. Too late we learn that such ideals cannot be recalled, though the recollection of them may have a humanizing influence on other times. But the abstractions of philosophy are to most persons cold and vacant; they give light without warmth; they are like the full moon in the heavens when there are no stars appearing. Men cannot live by thought alone; the world of sense is always breaking in upon them. They are for the most part confined to a corner of earth, and see but a little way beyond their own home or place of abode; they ‘do not lift up their eyes to the hills’; they are not awake when the dawn appears. But in Plato we have reached a height from which a man may look into the distance and behold the future of the world and of philosophy. The ideal of the State and of the life of the philosopher; the ideal of an education continuing through life and extending equally to both sexes; the ideal of the unity and correlation of knowledge; the faith in good and immortality—are the vacant forms of light on which Plato is seeking to fix the eye of mankind.
