The good writer seems to be writing about himself, but has his eye always on that thread of the universe which runs through himself, and all things.

—Ralph Waldo Emerson

While there have been many great writers who never wrote of themselves—Shakespeare comes to mind, of whom we know very little—it is certainly true that Emerson wrote reams about his cosmic self. His greatest book is his diary, an exploration of self that rivals Montaigne’s essays in depth and eloquence.

Writing about oneself, even modestly—and Emerson was not modest—inevitably involves self-mythologization. Emerson was the Homer of himself. He looked ever inward, and in his soul he found deities more alluring than Athena and battles more violent than the Trojan War. From this tumultuous inner life he created for himself a persona, a literary character, who both incorporated and transcended Emerson the man.

Everyone does this, to a certain extent. Identity is slippery, and the self is a vanishing figment of thought. As Hume pointed out, we are really just a floating observer embroiled in bundles of sensations. Each moment we become a new person.

Our past only exists in our memory, which is just an internal rumor that we choose to believe. And our feeble sense of history, itself always in flux, is the only thing that ties together the confused mass of colors, sounds, and textures, the swirling indistinct thoughts, the shadowy images and daydreams, that make up our mental life.

Your identity, then, is more like the water flowing down a stream than anything solid. The self is a process.

This groundlessness, this ceaseless change, makes people uncomfortable. So much of our lives consists of building solid foundations for our insubstantial selves. Culture can be thought of as a response to this existential uncertainty; we constantly try to banish the ambiguity of identity by giving ourselves social roles, roles that tell us who were are in relation to everyone else, and who everyone else is in relation to us.

Each moment of the day carries its own ritual performance with its concomitant roles. In trains we become passengers, in cars we become commuters on our way to work, at work we become a job title, and at home we become a husband or wife.

The ritual of marriage, for example, is performed to impose an identity on you. But in order for this imposed identity to persist, the community must, in a million big ways and small, act out this new social role. Being married is a habit: a habit of acting, of thinking about yourself, and a habitual way of treating you that friends, family, acquaintances, and even the federal government pick up.

A common way of reinforcing one’s identity is to attach it to something apparently solid, objective, and permanent. Thus people learn to equate their self-esteem with success, love, money, with their marriage or their job title. But these strategies can backfire. Marriages fail and jobs end, leaving people feeling lost. And if you identify your worth with your fame, skill, or with the size of your wallet, you doom yourself to perpetual envy, since there will always be those above you.

People also position themselves demographically; they identify themselves with their age, nationality, ethnicity, race, or gender. These strategies have the merit of at least pointing to something substantial. I know, for example, that my behavior is influenced by the fact that I am an American; and by being cognizant this identity, I understand certain behaviors of mine.

Nevertheless this too can be taken too far, specifically when people reduce themselves to members of a group, and attribute all their behaviors to the groups to which they belong. Your demographic identity influences your behavior, by shaping the pattern of your actions and thoughts, but it does not comprise your identity, since identity can never be pinned down.

Those with strong wills and forceful personalities, like Emerson, wrestle with this problem somewhat differently: they create a personal mythology. This is a process by which they select moments from their past, and omit others, and by this selection create for themselves a story with a definite arc.

At the end of this arc is their persona, which is a kind of personal role, a character they invented themselves rather than adopted from society, formed by exaggerating certain qualities and downplaying others. This persona, unlike their actual, shifting identity, is stable and fixed; and by mentally identifying with this persona of theirs, they manage to push aside, for a time, the groundlessness of self.

I can’t help admiring these self-mythologizers, these artists of the literary self, the Emersons, Montaignes, and Nietzsches, who put themselves together through force of will. This procedure does carry with it some dangers, however, the most notable being the risk that you may outgrow or tire of your persona.

I can only speak from my own experience. Many times in my life I have acted out a sort of character in social situations, either from shyness of showing my real self, or an attempt to impress others; and although this strategy worked for a time, it ended by being highly unsatisfying.

In effect I trained those around me to respond to me in certain ways, to consider me in a certain light, and when I got tired of this character I was left with friends who didn’t know me. They knew a part of me, to be sure, since any character I can invent for myself will always have some of my qualities, but they didn’t know the full range of my traits.

Emerson was well aware of this danger, which is why he made it a point to be changeful and inconsistent. As he repeatedly said, he had no system. He considered himself an experimenter who played continually with new ideas. This itself was a sort of persona—the mercurial prophet, the spontaneous me—but it gave him the flexibility to expand and shift.

To me, there is nothing wrong with mythologizing yourself. The important thing is to recognize that your persona is not your self, and not to let a fixed conception of your own character constrain your actions. A personality is nothing but a pattern of behavior, and this pattern only exists in retrospect. You as you exist now are a bubble of awareness floating down a stream of sensation, a bubble that forms and reforms every passing moment.
