3. heterogony of ends: a principle enunciated by Wundt ( Ethik 1886), according to which the development of religion and of codes of moral and social behaviour produced results that are to be distinguished from the cause of the development and were not intended at its outset; e.g. moral customs are regarded as (unforeseen) outgrowths from religious ceremonial.

1897 J. H. Gulliver et al. tr. W. Wundt Ethics I. 330 The law of the heterogony of ends. We mean to express by this name what is a matter of universal experience: that manifestations of will, over the whole range of man's free voluntary actions, are always of such a character that the effects of the actions extend more or less widely beyond the original motives of volition, so that new motives are originated for future actions, and again, in their turn, produce new effects.
1911 Encycl. Brit. XVIII. 241/2 Each particular will is directed to particular ends, but..beyond these ends effects follow as unexpected consequences, and..this heterogony produces social effects which we call custom.
