Rabbi Levi ben Gershon (1288–1344), also known by as Gersonides

Did God Originally Intend the World to Be Vegetarian?

After the flood, God permits humans to eat animals, whereas in Genesis 1, humans are told to eat plants. Interpreters have understood this to mean that vegetarianism was God’s original plan for humanity. Gersonides found the claim that God changed His mind scandalous, but this is more about countering Christian claims than the simple meaning of the text.
