Ecologist Paul Ehrlich stressed that people who hold opposing opinions need to engage in open discussion with well-reasoned dissent. Positions should be questioned and criticized, not the people who hold them. Personal attacks preclude open discussion because, once someone is put on the defensive, fruitful exchanges are impossible, at least for the moment.

Why is it that blood, rather than peace, sells?

Dominion does not mean domination. We hold dominion over animals only because of our powerful and ubiquitous intellect. Not because we are morally superior. Not because we have a right to exploit those who cannot defend themselves. Let us use our brain to move toward compassion and away from cruelty, to feel empathy rather than cold indifference, to feel animals' pain in our hearts.

~ Marc Bekoff

Many animals experience pain, anxiety and suffering, physically and psychologically, when they are held in captivity or subjected to starvation, social isolation, physical restraint, or painful situations from which they cannot escape. Even if it is not the same experience of pain, anxiety, or suffering undergone by humans- or even other animals, including members of the same species- an individual's pain, suffering, and anxiety matter.
