People want to work with somebody who feels shame, who worries about the perceptions of others. Dishonesty is something we don't like in others.

In Africa, we have the bush meat trade, which means that, on a very large scale, animals are being killed in the forests and sold in the cities as a luxury food.

Religion may have become a codification of morality, and it may fortify it, but it's not the origin of it.

Humans have a lot of pro-social tendencies.

When someone brutally kills someone else, we call him "animalistic." But we consider ourselves "human" when we give to the poor.

I am personally not against keeping animals at zoos, as they serve a huge educational purpose, but treating them well and with respect seems the least we could do, and with 'we' I mean not just zoo staff, but most certainly also the public.

The sturdiest pillars of human morality are compassion and a sense of justice.
