The human race is at the apex of all life-forms because, no matter how strenuously sociologists and politicians and others of their persuasion insist on defining our species into interest groups and factions and classes and tribes, the better to control us, in truth our greatest strength is in the uniqueness of each of us. Einstein, in his genius, can reveal to us much about the workings of the universe, and a child with Down syndrome can teach us, by his or her profound gentleness and humility, how urgently this troubled world needs kindness. Everyone has something to contribute.
