We do not need to eat animals, wear animals, or use animals for entertainment purposes, and our only defense of these uses is our pleasure, amusement, and convenience.
That's what literature is. It's the people who went before us, tapping out messages from the past, from beyond the grave, trying to tell us about life and death! Listen to them!
There are three deaths. The first is when the body ceases to function. The second is when the body is consigned to the grave. The third is that moment, sometime in the future, when your name is spoken for the last time.
