"As we totally abolish institutionalized animal slavery, we will continue to face conceptual challenges to which we will have to find intelligent solutions… I don’t know if I would send a human to prison for intentionally killing a fly or 20 flies. Intentional, deliberate killing of sentient creatures would be considered a crime in a just world. Why can’t we lock up a human for killing flies? Because it is ridiculous? Only to a speciesist. To a nonspeciesist with a punitive attitude, it is justified. … We cannot know the details of how things are gonna work themselves out in a future non-speciesist world. This will take a lot of thinking."
