People of many different faiths are inspired to be vegetarian at least in part by their religious beliefs. This book, Judaism and Vegetarianism, by Richard Schwartz, a retired professor of Mathematics, is one example. Published in hard copy in 2001, it is now available free online at www.jewishveg.com/JudaismAndVegetarianism/. . . .pdf
Here is an excerpt from an endorsement of the book by Rabbi David Rosen, former Chief Rabbi of Ireland:
Those who seek to live in accordance with the most sublime values of Judaism will find Richard Schwartz’s book an inspiration and guide for an authentic modern Jewish life that fulfils the injunction to “turn from evil and do that which is good, seek peace and pursue it.”
