At present scientists do not look for alternatives simply because they do not care enough about the animals they are using.

Had Rumsfeld said at any time 'get me a report on what's going on', he could have had it. You're right, it depends on choices that we make, which parts of the world we want to be in immediate contact with.

Hebrew word for "charity" tzedakah, simply means "justice" and as this suggests, for Jews, giving to the poor is no optional extra but an essential part of living a just life.

Cheats prosper until there are enough who bear grudges against them to make sure they do not prosper.

Typically, defenders of experiments on animals do not deny that animals suffer. They cannot deny the animals' suffering, because they need to stress the similarities between humans and other animals in order to claim that their experiments may have some relevance for human purposes. The experimenter who forces rats to choose between starvation and electric shock to see if they develop ulcers (which they do) does so because the rat has a nervous system very similar to a human being's, and presumably feels an electric shock in a similar way.

Were we incapable of empathy – of putting ourselves in the position of others and seeing that their suffering is like our own – then ethical reasoning would lead nowhere. If emotion without reason is blind, then reason without emotion is impotent.

What is there about the notion of a person, at law, that makes every living member of the species Homo sapiens a person, irrespective of their mental capacities, but excludes every nonhuman animal - again, irrespective of their mental capacities?
