A distinction that is more than mere semantics needs to be made between specific philosophical and political trends in the humane movement. The movement's historical basis is founded upon the morality of promoting kindness toward all creatures: reverence for all life. This approach has been strengthened by integrating ecological or eco-ethical principles and the emerging interdisciplinary animal welfare science. Furthermore, the movement has been enriched by the scholarship of moral philosophy, including the limited but valuable concept of animal 'rights.'
