The greatness of a nation and its moral progress can be judged by the way its animals are treated." ~ Mahatma Gandhi

Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter and the destruction of wilderness. We must take the final step in expanding the circle of ethics. ~Pete Singer

Compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind. ~Albert Schweitzer, Novel Peace Prize address, "The Problem of Peace in the World Today"

The assumption that animals are without rights and the illusion that our treatment of them has no moral significance is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality. ~Schopenhauer

Until we stop harming all other living beings, we are still savages. ~Thomas A. Edison
