When civilization becomes more than a phrase and religion reaches greater maturity, it will be realized that the sense and practice of kinship between all living beings is the soul of morality: such is the thesis here advanced in further expression of views long ago championed by the writer in his books, Animals' Rights and The Logic of Vegetarianism.
