[143] The most elaborate study of this character known to the present writer is Mr. G. Stanley Hall's _Adolescence_, in two volumes. The bulk of the work is, however, terrifying to some, and the cost prohibitive to many. For the general reader of limited leisure and means, Professor Starbuck's smaller volume, _The Psychology of Religion_, presents the salient facts in a brief and satisfactory manner. It is lacking, however, on the anthropological side, a view that is well presented by Dr. Stanley Hall. [144] See _Adolescence_, i. p. 528. [145] Vol. iii. p. 279. [146] _Psychology of Religion_, chap. iii. Hall's figures are given in the second volume of his work, pp. 288-92. [147] _Varieties_, p. 199. [148] An elaborate list of these ceremonies in both the savage and civilised worlds has been compiled by Mr. Hall, ii. chap. xiii.

It is now being recognised that a society is something more than a mere aggregate of self-contained units, and that the individual is quite inexplicable apart from the social group. It is the latter which gives the former his individuality. His earliest impressions are derived from the life of the group, and as he grows so he comes more and more under the influence of social forces. The consequence is that the key to a very large part of the phenomena of human nature is to be found in a study of group life. We may abstract the individual for purposes of examination, much as a physiologist may study the heart or the liver apart from the body from which it has been taken. But ultimately it is in relation to the whole that the true significance and value of the part is to be discerned.
