Part of the speech to the students of the Georgia Institute of Technology, On the subject of humane slaughter (Summer 2010)
Context: Exactly what is your definition of humane? Besides psychological and physical abuse, torture, dismemberment and murder, what else do you think happens to animals inside of a slaughterhouse? Do you think they get belly rubs and tushy slaps? And if you think there is such a thing as humane slaughter. I'm curious, do you also think there is such a thing as humane rape? Humane child molestation? Humane slavery? How about a humane holocaust? In fact, what is your definition of a holocaust? Is it a massacre of human beings, or a massacre of innocent beings?

Context: You can never be too cautious in your prognosis, in the view of the great uncertainty of the course of any disease not long watched, and the many unexpected turns it may take.
I think I am not the first to utter the following caution : —
Beware how you take away hope from any human being. Nothing is clearer than that the merciful Creator intends to blind most people as they pass down into the dark valley. Without very good reasons, temporal or spiritual, we should not interfere with his kind arrangements. It is the height of cruelty and the extreme of impertinence to tell your patient he must die, except you are sure that he wishes to know it, or that there is some particular cause for his knowing it. I should be especially unwilling to tell a child that it could not recover; if the theologians think it necessary, let them take the responsibility. God leads it by the hand to the edge of the precipice in happy unconsciousness, and I would not open its eyes to what he wisely conceals.
