The old age of Plato seems to have been marked by restless activity in more directions than one. He began various works which were never finished, and projected others which were never begun. He became possessed by a devouring zeal for social reform. It seemed to him that nothing was wanting but an enlightened despot to make his ideal State a reality. According to one story, he fancied that such an instrument might be found in the younger Dionysius. If so, his expectations were speedily disappointed. As Hegel acutely observes, only a man of half measures will allow himself to be guided by another; and such a man would lack the energy needed to carry out Plato’s scheme.[158] However this may be, the philosopher does not seem to have given up his idea that absolute monarchy was, after all, the government from which most good might be expected. A process of substitution which runs through his whole intellectual evolution was here exemplified for the last time. Just as in his ethical system knowledge, after having been regarded solely as the means for procuring an ulterior end, pleasure, subsequently became an end in itself; just as the interest in knowledge was superseded by a more absorbing interest in the dialectical machinery which was to facilitate its acquisition, and this again by the social re-organisation which was to make education a department of the State; so also the beneficent despotism originally invoked for the purpose of establishing an aristocracy on the new model, came at last to be regarded by Plato as itself the best form of government. Such, at least, seems to be the drift of a remarkable Dialogue called the _Statesman_, which we agree with Prof. Jowett in placing immediately before the _Laws_. Some have denied its authenticity, and others have placed it very early in the entire series of Platonic compositions. But it contains passages of such blended wit and eloquence that no other man could have written them; and passages so destitute of life that they could only have been written when his system had stiffened into mathematical pedantry and scholastic routine. Moreover, it seems distinctly to anticipate the scheme of detailed legislation which Plato spent his last years in elaborating. After covering with ridicule the notion that a truly competent ruler should ever be hampered by written enactments, the principal spokesman acknowledges that, in the absence of such a ruler, a definite and unalterable code offers the best guarantees for political stability.
