In the first place, there is a notable discrepancy between the biological and the sociological aspect. For the complete development of the individual life implies that every function should be fulfilled, and that its fulfilment should interfere with the performance of no other function. "The performance of every function is, in a sense, a moral obligation." "The ideally moral man ... is one in whom the functions of all kinds are duly fulfilled,"--that is to say, "discharged in degrees duly adjusted to the conditions of existence."[239] A fully evolved life is marked by multiplicity and complexity of function. And, if from the individual we pass to the social organism, we find that the same truth holds. The state, or organised body of individuals, has many functions to perform; but it can only perform them in the most efficient way through the functions of its individual members being specialised. From the social point of view, therefore, the greatest possible division of labour is a mark of the most evolved and perfect community. And this division of labour implies that each individual, instead of performing every function of which he is capable, should be made to restrict himself to that at which he is best, so that the community may be the gainer from the time and exertion that are saved, and the skill that is produced, by the most economic expenditure of individual talent. Thus social perfection appears to imply a condition of things inconsistent with that development of one's whole nature which, from the biological point of view, has just been defined as a characteristic of the ideally moral man. It seems, indeed, inevitable that any such abstract preliminary notion of development as that which would test it by increase of complexity must fail in such a case as this where there is no question between the competing claims of two phenomena on the same level, but where harmony is wanted between the different aspects the same phenomena present when looked at from the point of view of the individual and from the point of view of the whole.
