Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.

We can no more justify using nonhumans as human resources than we can justify human slavery. Animal use and slavery have at least one important point in common: both institutions treat sentient beings exclusively as resources of others. That cannot be justified with respect to humans; it cannot be justified with respect to nonhumans-however "humanely" we treat them.

Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.
