It is universally acknowledged that there is a great uniformity among the actions of men, in all nations and ages, and that human nature remains still the same, in its principles and operations. The same motives always produce the same actions: The same events follow from the same causes. Ambition, avarice, selflove, vanity, friendship, generosity, public spirit: these passions, mixed in various degrees, and distributed through society, have been, from the beginning j of the world, and still are, the source of all the actions and enterprises, which have ever been observed among mankind. Would you know the sentiments, inclinations, and course of life of the Greeks and Romans? Study well the temper and actions of the French and English: You cannot be much mistaken in transferring to the former most of the observations which you have made with regard to the latter. Mankind are so much the same, in all times and places, that history informs us of nothing new or strange in this particular. Its chief use is only to discover the constant and universal principles of human nature, by showing men in all varieties of circumstances and situations, and furnishing us with materials from which we may form our observations and become acquainted with the regular springs of human action and behaviour. These records of wars, intrigues, factions, and revolutions, are so many collections of experiments, by which the politician or moral philosopher fixes the principles of his science, in the same manner as the physician or natural philosopher becomes acquainted with the nature of plants, minerals, and other external objects, by the experiments which he forms concerning them. Nor are the earth, water, and other elements, examined by Aristotle, and Hippocrates, more like to those which at present lie under our observation than the men described by Polybius and Tacitus are to those who now govern the world.

The realm of fairy-story is wide and deep and high and filled with many things: all manner of beasts and birds are found there; shoreless seas and stars uncounted; beauty that is an enchantment, and an ever-present peril; both joy and sorrow as sharp as swords. In that realm a man may, perhaps, count himself fortunate to have wandered, but its very richness and strangeness tie the tongue of a traveller who would report them. And while he is there it is dangerous for him to ask too many question, lest the gates should be shut and the keys be lost.

If there were in the world a sincere and total pessimism, it would of necessity be silent. The despair which finds a voice is a social mood, it is the cry of misery which brother utters to brother when both are stumbling though a valley of shadows which is peopled with — comrades. In its anguish it bears witness to something that is good in life, for it presupposes sympathy. ... The real gloom, the sincere despair, is dumb and blind; it writes no books, and feels no impulse to burden an intolerable universe with a monument more lasting than brass.

According to classical theistic belief — classical Muslim and Jewish as well as Christian belief — first of all there is God, the chief being of the universe, who has neither beginning nor end. Most important, God is personal. That is, God is the kind of being who is conscious and enjoys some kind of awareness of his surroundings (in God's case, that would be everything). Second (though not second in importance), a person has loves and hates, wishes and desires; she approves of some things and disapproves of others; she wants things to be a certain way. We might put this by saying that persons have affections. A person, third, is a being who has beliefs and, if fortunate, knowledge. We human beings, for example, believe a host of things... Persons, therefore, have beliefs and affections. Further, a person is a being who has aims and intentions; a person aims to bring it about that things should be a certain way, intends to act so that things will be the way he wants them to be... Finally, persons can often act to fulfill their intentions; they can bring it about that things are a certain way; they can cause things to happen. To be more technical (though not more insightful or more clear), we might say that a person is a being who can actualize states of affairs. Persons can often act on the basis of what they believe in order to bring about states of affairs whose actuality they desire. ¶ So a person is conscious, has affections, beliefs, and intentions, and can act... First, therefore, God is a person. But second, unlike human persons, God is a person without a body. He acts, and acts in the world, as human beings do, but, unlike human beings, not by way of a body. Rather, God acts just by willing: he wills that things be a certain way, and they are that way. (God said "Let there be light"; and there was light.)

The source of the word "humorist" is one who regards human beings in terms of their humors, you know, whether they're sanguine or full of yellow bile, or whatever the four classical humors are. You stand back from people and regard them as types. And one finds, especially by the time one reaches one's fifties, that there are a limited number of types of people in the world, and you went to high school with every single one of them. You can visit the Eskimos, you can visit the Bushmen in the Kalahari, you can go to Israel, you can go to Egypt, but everybody you meet is going to be somebody you went to high school with.

This lack of a sense of history has allowed us a kind of romance with race and ethnicity that is fanciful. I did a documentary some years ago about America and teenagers and the past and all these kids who were announcing themselves as wanting to recover their history, as though it was some reassurance, when everything I've ever read about American history is an embarrassment. It's filled with tragedies of all kinds. The notion that we would study history in order to feel better about ourselves is just ludicrous. But we have this romantic sense because we know it so little, our past really seems noble. I don't look to Aztec Mexico for any reassurance about my identity. I'm aware that Aztec Mexico was a decadent society; its bloodlust was so extreme that its ultimate sexual energy was its pursuit of death. There's nothing in that history for me that leads me to the romantic calendars that you see in Mexican restaurants with the Aztec, almost naked with the feathers coming out of his head, and the Aztec princess at his knees. Nothing of that is convincing to me. History is a terrible, terrible burden which we need to confront, but I don't think the search for authenticity begins there.

Noting that we're all human beings can be worthwhile, but it can also be a verbal white flag for abject moral surrender. Put another way: All the great political and moral conflicts have been between human beings. To date, civilization's greatest battles — rhetorical or otherwise — have not been with Styrofoam, dog hair, gerbils, or toe jam. Nazis are human beings. Murderers and pedophiles are human beings. To say that humanity somehow exonerates rather than confers accountability is to say that humanity is in fact meaningless. Joe Blow killed a child? Well, he's just a human being — cut him some slack. Sure, Jack the Ripper was a rough chap, but he was a carbon-based life form.

Winning the race to happiness is problematic, but so is knowing where to start and finish and which direction to run. Philosophy is no help. "Very little is needed to make a happy life," said Marcus Aurelius. Tell it to the kids on a rainy day, Marco, when the DVD player is on the fritz, the Game Boy is out of batteries, and the SUV won't start. "Happiness is activity in accordance with excellence," said Aristotle, who must have been a better golfer than I am. The Epicureans would be expected to know something about pursuing happiness. Epicurus said, "Pleasure is the beginning and the end of living happily." I'll get the gin, you find some olives and vermouth. But then Epicurus went on to say, "It is impossible to live pleasurably without living wisely, well, and justly." Fine, for people who pursue their happiness by eating oat bran, reading St. Peter's Epistles, and not ducking out of jury duty. Solon of Athens declared, "Until he is dead, do not yet call a man happy." And then what do you call him?

Happiness isn't impossible to describe. But, paradoxically, no one can listen to descriptions of happiness for long. Compare Dante's Inferno with Dante's Paradiso. Dante's beloved Beatrice would have died of boredom if he had tried reading to her from Paradiso rough drafts. On a less exalted plane, let any huggy-lovey couple show you their honeymoon slides.

Nature provides no moral messages for our complex and confusing lives. But this evolutionary argument for construing the "essence" of humanity as the sum total of our variation within the discrete boundaries of our species does provide an important insight into what might be called the biological meaning of human equality. If all living humans form one distinct historical entity, not a set of stages in a continuum leading backward into our evolutionary ancestry, then we cannot order our variation into any ranking of worth based on "higher" or "lower" stages. A person becomes a full human being by genealogical membership within our evolutionarily discrete species, and not by possessing "essential" traits that we may happen to judge as more valuable than others: the strength of Mark McGwire or the brains of Albert Einstein. In this sense, we must regard the birthright of humanity as being truly inalienable in the most literal way. A person born into this biological entity cannot sell his or her membership for a mess of pottage or for all the world's gold and power. Every human being contributes equally to the full variation that defines our essence. In this sense, the most mentally limited person remains as fully and completely human as McGwire or Einstein. This truly biological view of human essences can only elevate the familiar words of Tiny Tim to more than a saccharine pronouncement at the end of kiddie Christmas specials: "God Bless Us, Every One!"
