Though he is no longer fired with dialectical enthusiasm, he would compel the guardians to 'look at one idea gathered from many things,' and to 'perceive the principle which is the same in all the four virtues.' He still recognizes the enormous influence of music, in which every youth is to be trained for three years; and he seems to attribute the existing degeneracy of the Athenian state and the laxity of morals partly to musical innovation, manifested in the unnatural divorce of the instrument and the voice, of the rhythm from the words, and partly to the influence of the mob who ruled at the theatres. He assimilates the education of the two sexes, as far as possible, both in music and gymnastic, and, as in the Republic, he would give to gymnastic a purely military character. In marriage, his object is still to produce the finest children for the state. As in the Statesman, he would unite in wedlock dissimilar natures--the passionate with the dull, the courageous with the gentle. And the virtuous tyrant of the Statesman, who has no place in the Republic, again appears. In this, as in all his writings, he has the strongest sense of the degeneracy and incapacity of the rulers of his own time. In the Laws, the philosophers, if not banished, like the poets, are at least ignored; and religion takes the place of philosophy in the regulation of human life. It must however be remembered that the religion of Plato is co-extensive with morality, and is that purified religion and mythology of which he speaks in the second book of the Republic. There is no real discrepancy in the two works. In a practical treatise, he speaks of religion rather than of philosophy; just as he appears to identify virtue with pleasure, and rather seeks to find the common element of the virtues than to maintain his old paradoxical theses that they are one, or that they are identical with knowledge. The dialectic and the idea of good, which even Glaucon in the Republic could not understand, would be out of place in a less ideal work. There may also be a change in his own mind, the purely intellectual aspect of philosophy having a diminishing interest to him in his old age.
