Religion is a strictly human infirmity. No other animal has it. It originated far back in the past, when the human world was young and the mind just … - J. Howard Moore

The animate environment has been the most formidable factor in the evolution of mundane life. The inanimate has been indifferent. The animate has not been so. It has been relentless. While the ages were yet tender, life began to riot upon life, and it has continued to do so to this moment. Where the inanimate has slain and selected one, the animate has slain multitudes. It is estimated that the life process is now about twenty millions of years old. Its existence has been one unbroken bacchanal of blood. Aggregate has preyed upon aggregate and species has decimated species. Tides of irresponsibles have swept over the continents and thru the deeps, collided, grappled, and exterminated each other. What is hidden in the horrible chasm between monera and man, no fancy will ever illume. It is the mighty charnal of creation. The skeletons of two millions of exterminated species of living beings are there with all their unimaginable accompaniments—wars, blacknesses, frightful manglings, eclipses, horrible concussions, inextinguishable malignities, hell.

[T]o the prophet, that supermundane soul who has heard the secrets and intentions of the universe, the grand confederation of all the graceful races and species of the earth into one universal scheme of consideration, is as inevitable as the processes of evolution. The deprecations to-day of the most wanton crimes perpetrated by the human on associated species, seen in societies for the prevention of cruelties of various sorts, are but the dawn-peeps of a clearer consciousness and of more sweeping and consistent consideration. The ideal relation of the inhabitants of the universe to each other, then, is that relation which will most actively conduce to the welfare of the universe; and the welfare of the universe means, not the welfare of any one individual or guild, but the welfare of all the beings who now inhabit it, and of those who shall come after—the welfare of that mighty and immortal personality who comprehends all species and continues from generation to generation—the Sentient Cosmos.

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.
