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.
