The beings of this world have been evolved. They have all been formed according to the same general plan, and filled with similar susceptibilities. N… - J. Howard Moore

In The Universal Kinship, Howard Moore left to humanitarians a treasure which it will be their own fault if they do not value as it deserves. There is a tendency to forget that it is to modern evolutionary science that the ethic of humaneness owes its strongest corroboration. The physical basis of the humane philosophy rests on the biological fact that kinship is universal. Starting from this admitted truth, Moore showed, with much wealth of argument and epigram, that the supposed psychical gulf between human and non-human has no more existence, apart from the imagination of man. than the physical gulf which has now been bridged by science. The purpose of our movement was admirably stated by him: "to put science and humanitarianism in place of tradition and savagery." It was with that aim in view that our League of Humaneness had been formed.

Man has been so long accustomed to the undisputed privilege of spoliation, and has so long and so brilliantly imagined himself to be all there is in the world, that a proposition denying this privilege, however fair the proposition may be from an impartial point of view, is promptly classified as the allegation of a zany, and is supposed to be conclusively disposed of when it is shown to be capable of interfering with human convenience or pleasure.

In the ideal state, man treats the races of beings affiliated with him, not as objects of pillage, but as beings with rights and feelings and capabilities of happiness and misery, like himself.
