the water-photographer had presented it was like a bell whose reverberations hang on the air for a long time, becoming quieter and quieter but never seeming to do something as simple as stop. Socrates, or Plato, seems determined to stop it. The question arises that arises with many works of art: does the work mean what the artist intended it to mean, does Meno’s argument mean what he or Plato intended it to mean? Or is it larger than they intended? For it is not, after all, really a question about whether you can know the unknown, arrive in it, but how to go about looking for it, how to travel.
For most of the dialogue, Socrates rebuts and attacks Meno with logic and argument and even mathematics. But for this question he shifts into mysticism—that is, into unsubstantiatable and poetic assertion. After his first dismissive reply, he adds, “And they say—mark, now, and see whether their words are true—they say that the soul of man is immortal, and at one time has an end, which is termed dying, and at another time is born again, but is never destroyed. And the moral is, that a man ought to live always in perfect holiness. ‘For in the ninth year Persephone sends the souls of those from whom she has received the penalty of ancient crime back again from beneath into the light of the sun above, and these are they who become noble kings and mighty men and great in wisdom and are called saintly heroes in after ages.’ The soul, then, as being immortal, and having been born again many times, and having seen all things that exist, whether in this world or in the world below, has knowledge of them all . . . all enquiry and all learning is but recollection.” Socrates says you can know the unknown because you remember it. You already know what seems unknown; you have been here before, but only when you were someone else. This only shifts the location of the unknown from unknown other to unknown self. Meno says, Mystery. Socrates says, On the contrary, Mystery. That much is certain. It can be a kind of compass.
What follows are a few of my own maps.
The Blue of Distance
T he world is blue at its edges and in its depths. This blue is the light that got lost. Light at the blue end of the spectrum does not travel the whole distance from the sun to us. It disperses among the molecules of the air, it scatters in water. Water is colorless, shallow water appears to be the color of whatever lies underneath it, but deep water is full of this scattered light, the purer the water the deeper the blue. The sky is blue for the same reason, but the blue at the horizon, the blue of land that seems to be dissolving into the sky, is a deeper, dreamier, melancholy blue, the blue at the farthest reaches of the places where you see for miles, the blue of distance. This light that does not touch us, does not travel the whole distance, the light that gets lost, gives us the beauty of the world, so much of which is in the color blue.
For many years, I have been moved by the blue at the far edge of what can be seen, that color of horizons, of remote mountain ranges, of anything far away. The color of that distance is the color of an emotion, the color of solitude and of desire, the color of there seen from here, the color of where you are not. And the color of where you can never go. For the blue is not in the place those miles away at the horizon, but in the atmospheric distance between you and the mountains. “Longing,” says the poet Robert Hass, “because desire is full of endless distances.” Blue is the color of longing for the distances you never arrive in, for the blue world. One soft humid early spring morning driving a winding road across Mount Tamalpais, the 2,500-foot mountain just north of the Golden Gate Bridge, a bend reveals a sudden vision of San Francisco in shades of blue, a city in a dream, and I was filled with a tremendous yearning to live in that place of blue hills and blue buildings, though I do live there, I
