Harold Fromm criticizes vegans for their vanity and pretentious sense of virtue. "However delicate our moral sensibilities, it still remains that to be alive is to be a murderer," he says. "We're compromised from the start. Evolution favored meat-eating primates, enlarging their brains and enabling them to live in more and more complex and survivalist societies that today extend our life spans, provide genteel habitats, and produce philosophers who have the wherewithal to object to the very components of their own existence. Death is the only form of purification. Alive, we have no choice but to accept our complicity, because life is a product of death. Do as much as you can to minimize the damage, because the 'environment' is us."
