Our task today is to examine the movement of opinion which has been outlined, in the light of social theory. We held that social progress consists in a harmonious development, and we further defined this conception as including a harmony in the development of the personal life of the members of society, and in the working out and fulfilment of the various and at first sight divergent elements of value which constitute the well-being of the social order. In the movement of opinion we have seen a certain conflict of ideals and our question is whether, if we probe deeper, a basis of reconstruction can be found. To find an answer let us take up the question afresh. Let us start with the conception of the social order which the principle of harmonious development would suggest. Let us consider to what view of the functions of the state and the rights of the individual it would lead and let us, in order to observe the limitations of time, deal with the question with special reference to the problem of liberty.

To begin with, the general theory of society indicated by the ideal of harmonious development is clearly one of co-operation. We may say, with Aristotle, that society is an association of human beings with a view to the good life.
