element—something which it is not yet and which under certain conditions it is to be. In that sense Greek Moral Philosophy is essentially idealistic. Further it is always assumed that all human practical activity is directed or "oriented" to a single end, and that that end is knowable or definable in advance of its realisation. To know it is not merely a matter of speculative interest, it is of the highest practical moment for only in the light of it can life be duly guided, and particularly only so can the state be properly organised and administered. This explains the stress laid throughout by Greek Moral Philosophy upon the necessity of knowledge as a condition of the best life. This knowledge is not, though it includes knowledge of the nature of man and his circumstances, it is knowledge of what is best—of man's supreme end or good.
But this end is not conceived as presented to him by a superior power nor even as something which ought to be. The presentation of the Moral Ideal as Duty is almost absent. From the outset it is identified with the object of desire, of what we not merely judge desirable but actually do desire, or that which would, if realised, satisfy human desire. In fact it is what we all, wise and simple, agree in naming "Happiness" (Welfare or Well-being).
In what then does happiness consist? Aristotle summarily sets aside the more or less popular identifications of it with abundance of physical pleasures, with political power and honour, with the mere possession of such superior gifts or attainments as normally entitle men to these, with wealth. None of these can constitute the end or good of man as such. On the other hand, he rejects his master Plato's conception of a good which is the end of the whole universe, or at least dismisses it as irrelevant to his present enquiry. The good towards which all human desires and practical activities are directed must be one conformable to man's special nature and circumstances and attainable by his efforts. There is in Aristotle's theory of human conduct no trace of Plato's "other worldliness"; he brings the moral ideal in Bacon's phrase down to "right earth"—and so closer to the facts and problems of actual human living. Turning from criticism of others he states his own
