To the Editor:
Adam Shriver applauds the possibility that we may soon be able to reduce the discomfort of the animals we choose to raise in the horrific warehouses of factory farms through neuroscience. I’d like to propose an alternative: that we consider using neuroscience and genetic engineering to modify humans so that they derive less pleasure from consuming large amounts of animal flesh and more pleasure from consuming things like tofu.
Another option, of course, is that we leave both humans and animals unmodified and instead encourage the humans to use their superior intelligence, freer wills and more developed moral sense to see how deeply repellent it is for humans to continue to devote so much energy to find new ways of exploiting animals so that they can have tasty morsels on their plates.
