Dynamic Sociology is the art of improving society; happiness is its end ; and its means is the universal diffusion of scientific information. The first volume traces the development of human society from an originally homogeneous matter which suffers primary aggregation in cosmogony, secondary aggregation in biogeny, psychogeny and anthropogeny, and tertiary aggregation in sociogeny. The second volume works back from the end of happiness through a chain of means-progress, dynamic action,
... amic action, dynamic opinion, knowledge-to education. In developing the main thesis of his work, the author abstracts to the last degree from man's practical nature. The social unit is a centre of more or less information; truth is a large number of facts and generalisations which it is the business of education to impart. In so far as education leaves this task in order even to ' develop the intellect' it forsakes its proper function and is lost labour. The author does not show how the diffusion of abstract information is to be adequate to the realisation of a more perfect society; but he is convinced of its paramount importance, and seems to regard his theory as almost self-evident. He says, for instance, that ' the complete ignorance of so-called cultivated people as to the nature of cells in biology and of the fact that they have each been evolved from a simple cell, shuts them off from a knowledege of the most important truth of their existence '. This sentence is quite typical of Mr. Ward's whole point of view, which confuses importance within special sciences with importance in relation to conduct. G. SANDEMAN.
