The Logic of Vegetarianism 

It is the special purpose of this book to set forth in a clear and rational manner the logic of vegetarianism. To the ethical, the scientific, and the economic aspects of the system much attention has already been given by well-accredited writers, but there has not as yet been any organised effort to present the logical view—that is, the dialectical scope of the arguments, offensive and defensive, on which the case for vegetarianism is founded. I am aware that mere logic is not in itself a matter of first rate importance, and that a great humane principal, based on true natural instinct, will in the long run have fulfilment, whatever wordy battles may rage around it for a time; nevertheless, there is no better method of hastening that result than to set the issues before the public in a plain and unmistakable light. I wish, therefore, in this work, to show what vegetarianism is, and (a scarcely less essential point) what vegetarianism is not.
