Proponents of euthanasia do not understand human dignity, which, at best, they confuse with humaneness. One of their favorite arguments proves this point: why, they say, do we put animal out of their misery but insist on compelling fellow human being to suffer to the bitter end? Why, if it is not a contradiction for the veterinarian, does the medical ethic absolutely rule our mercy killing? Is this not simply inhumane?
Perhaps inhumane, but not thereby inhuman. On the contrary, it is precisely because animals are not human that we must treat them (merely) humanely. We put dumb animals to sleep because they do not know that they are dying, because they can make nothing of their misery or mortality, and because, therefore, they cannot live deliberately – that is, humanly – in the face of their own suffering or dying. They cannot live out a fitting end. Compassion for their weakness and dumbness is our only appropriate emotion, and given our responsibility for their care and well-being, we do the only humane thing we can. But when a conscious human being asks us for death, by that very action he displays the presence of something that precludes our regarding him as a dumb animal. Humanity is owed humanity, not humaneness. Humanity is owed the bolstering of the human, even or especially in its dying moments, in resistance to the temptation to ignore its presence in the sight of suffering.
What humanity needs most in the face of evils is courage, the ability to stand against fear and pain and thoughts of nothingness. The deaths we most admire are those of people who, knowing that they are dying, face the fact frontally and act accordingly: they set their affairs in order, they arrange what could be final meetings with their loved ones, and yet, with strength of soul and a small reservoir of hope, they continue to live and work and love as much as they can for as long as they can. Because such conclusions of life require courage, they call for our encouragement – and for the many small speeches and deeds that shore up the human spirit against despair and defeat.
