I like," said Emerson, "dry light, and hard clouds, hard expressions, and hard manners." The writers who become our saints and sages, the wise men of our tribe, they who help us to live—there is only one way by which we can know them: their genius for compression. They are the ones who are always stripping life down to fundamentals and essentials, to aphorisms and parables and riddles, and if we ask what is holy about men whose life sayings often shock and hurt as much as they illuminate, the answer is that the final compression they get into their speech is a compression they have attained in their lives. The absolute in their writing is an absolute they have learned to live, and the sometimes overemphatic sharpness, the well-known intolerance by holy men, the cutting blow, the very quickness with which they sum up life and eternity in a sentence, is only the expression in words of the attempt to meet existence with the greatest possible directness.
This is what Thoreau meant when he said that he wanted to "drive life into a corner," when he appealed to his distracted countrymen: "Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance . . . till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake." The imagery—one might better say the music—with which he brings to an ecstatic end this second chapter of Walden is a whirl of variations on the single theme of the ultimate, the "point d'appui below freshet and frost and fire"—bedrock, facing a fact until it divides you through the heart and marrow like a sword, the sky whose bottom is pebbly with stars, the deep deep earth through which the intellect works like a cleaver. Thoreau, because he yearned to possess the infinite spaces suggested to him by his imagination, wanted to base this infiniteness on some image that would be immediately graspable, that would look so sharp and definite and accessible, in his telling of it, that he could lead you up to it, make you feel it, give it to you. Blake spoke of "the world in a grain of sand"; Thoreau's desire was to make you feel this in the ultimate sensation that man could possibly express of his connection with nature. If he could have rolled himself up in the world, have tasted it in every cell of his being, this and this alone would have made him feel that he was communicating his supreme privilege of ecstasy. And it is the attempt to mark this sensation of maximum contact that he tried to get into his prose—"wildness," the taste of a muskrat eaten raw, walking blind through dark woods at night, a swim in the infinite silence of Walden Pond. Fundamentally, Thoreau's best writing is an attempt to get up to the point where he can reduce human experience to communion with nature and this communion to images of total physical ecstasy.
But this same need of compression, of the absolute expression, of the ultimate in speech that will condense and contract your whole experience, can find easier forms. In Emerson, whom we tend these days to underestimate because of the priggishness that so often wars with his genius, the poet's need of condensation takes the form of epigram. There are epigrams in Thoreau, too, perhaps even more of them; but they are the steps up to his temple, the rehearsals of his style; they do not express the reaches of his ultimate feeling. In Emerson, on the other hand, epigrams, aperçus, bare notations which seem to cross his journal in a single motion from his eye to his hand, serve for that sidelong glance into things which expresses him far more characteristically than the ecstasies described in his first book, Nature. For Emerson's conception of himself was not as a solitary walker in nature but as an oracle, a clairvoyant, a seer; and his truest moments come when he speaks in slightly veiled disclosures from on high, when he exemplifies the quality that Thoreau missed in Carlyle—he retires "behind the truth he utters."
Emerson's compressiveness takes the form of intellectual wit, of the sentence that gives you not a description of external nature to be embraced, but a definition of things in which you can rest. He exemplifies the traditional role of the founder of new religions by providing his audience, his possible disciples, with a set of maxims which give spiritual tangibility to the otherwise nameless and indistinct blur of the outside world. Such maxims are definite names for spiritual things and so convince us of their reality; they lay down a pattern of steppingstones across what would otherwise be the terror of an utterly alien world. Without man, there is utter silence; a true sentence cuts into this silence and gives man a habitation in the universe. "The maker of a sentence, like the other artist," Emerson wrote in 1834, "launches out into the infinite and builds a road into Chaos and Old Night, and is followed by those who hear him with something of wild, creative delight." Emerson's sentences are compressed because they are pronouncements; they show the way; they teach. He thought so habitually in "sayings" that he himself found "each sentence an infinitely repellent particle."
