If one were asked to name the cardinal virtue of Thoreau's philosophy, it would be hard to identify a better candidate than awareness. He attests to the importance of “being forever on the alert,” and of “the discipline of looking always at what is to be seen” (Walden, IV). This exercise may enable one to create remarkably minute descriptions of a sunset, a battle between red and black ants, or the shapes taken by thawing clay on a sand bank: but its primary value lies in the way it affects the quality of our experience. “It is something to be able to paint a particular picture, or to carve a statue, and so to make a few objects beautiful; but it is far more glorious to carve and paint the very atmosphere and medium through which we look” (Walden, II). Awareness cannot be classified as exclusively a moral or an intellectual virtue, either, since knowing is an inescapably practical and evaluative activity. Thoreau has been interpreted as offering an original response to the major problem of modern philosophy, since he recognizes that knowledge is “dependent on the individual's ability to see,” and that “the world as known is thus radically dependent on character” (Tauber 2001, 4–5). One of the common tenets of ancient philosophy which was abandoned in the period beginning with Descartes is that a person “could not have access to the truth” without undertaking a process of self-purification that would render him “susceptible to knowing the truth” (Foucault 1997, 278–279). For Thoreau, it was the work of a lifetime to cultivate one's receptivity to the beauty of the universe. Believing that “the perception of beauty is a moral test” (Journal, 6/21/52), Thoreau frequently chastises himself or humanity in general for failing in this respect. “How much of beauty—of color, as well as form—on which our eyes daily rest goes unperceived by us,” he laments (Journal, 8/1/60); and he worries that “Nature has no human inhabitant who appreciates her” (Walden, IX). Noticing that his sensory awareness has grown less acute since the time of his youth, he speculates that “the child plucks its first flower with an insight into its beauty and significance which the subsequent botanist never retains” (Journal, 7/16/51 & 2/5/52). In order to attain a clear and truthful view of things, we must refine all the perceptual faculties of our embodied consciousness, and become emotionally attuned to all the concrete features of the place in which we are located. We fully know only those facts that are “warm, moist, incarnated,” and palpably felt: “A man has not seen a thing who has not felt it” (Journal, 2/23/60). Since our ability to appreciate the significance of phenomena is so easily dulled, it requires a certain discipline in order to become and remain a reliable knower of the world. Like Aristotle, Thoreau believes that the perception of truth “produces a pleasurable sensation”; and he adds that a “healthy and refined nature would always derive pleasure from the landscape” (Journal, 9/24/54 & 6/27/52). Nature will reward the most careful attention paid by a person who is appropriately disposed, but there is only “as much beauty visible to us in the landscape as we are prepared to appreciate,—not a grain more. The actual objects which one person will see from a particular hilltop are just as different from those which another will see as the persons are different” (Journal, 11/4/58). One who is in the right state to be capable of giving a “poetic and lively description” of things will find himself “in a living and beautiful world” (Journal, 10/13/60 & 12/31/59). Beauty, like color, does not lie only in the eye of the beholder: flowers, for example, are indeed beautiful and brightly colored. Nevertheless, beauty—and color, for that matter—can exist only where there is a beholder to perceive it (Journal, 6/15/52 & 1/21/38). From his experience in the field making observations of natural phenomena, Thoreau gained the insight “that he, the supposedly neutral observer, was always and unavoidably in the center of the observation” (McGregor 1997, 113). Because all perception of objects has a subjective aspect, the world can be defined as a sphere centered around each conscious perceiver: wherever we are located, “the universe is built around us, and we are central still” (Journal, 8/24/41). This does not mean that we are trapped inside of our own consciousness; rather, the point is that it is only through the lens of our own subjectivity that we have access to the external world. What we are able to perceive, then, depends not only upon where we are physically situated: it is also contingent upon who we are and what we value, or how our attention is focused. “Objects are concealed from our view, not so much because they are out of the course of our visual ray as because we do not bring our minds and eyes to bear on them…. A man sees only what concerns him” (“Autumnal Tints”). In other words, there is “no such thing as pure objective observation. Your observation, to be interesting, i.e. to be significant, must be subjective” (Journal, 5/6/54). Subjectivity is not an obstacle to truth, according to Thoreau. After all, he says, “the truest description, and that by which another living man can most readily recognize a flower, is the unmeasured and eloquent one which the sight of it inspires” (Journal, 10/13/60). A true account of the world must do justice to all the familiar properties of objects that the human mind is capable of perceiving. Whether this could be done by a scientific description is a vexing question for Thoreau, and one about which he shows considerable ambivalence. One of his concerns is that the scientist “discovers no world for the mind of man with all its faculties to inhabit”; by contrast, there is “more humanity” in “the unscientific man's knowledge,” since the latter can explain how certain facts pertain to life (Journal, 9/5/51, 2/13/52). He accuses the naturalist of failing to understand color, much less beauty, and asks: “What sort of science is that which enriches the understanding, but robs the imagination?” (Journal, 10/5/61 & 12/25/51) Thoreau sometimes characterizes science as an ideal discipline that will enrich our knowledge and experience: “The true man of science will know nature better by his finer organization; he will smell, taste, see, hear, feel, better than other men. His will be a deeper and finer experience” (“Natural History of Massachusetts”). Yet he also gives voice to the fear that by weighing and measuring things and collecting quantitative data he may actually be narrowing his vision. The scientist “studies nature as a dead language,” and would rather study a dead fish preserved in a jar than a living one in its native element (Journal, 5/10/53 & 11/30/58). In these same journal entries, Thoreau claims that he seeks to experience the significance of nature, and that “the beauty of the fish” is what is most worthy of being measured. On the other hand, when he finds a dead fish in the water, he brings it home to weigh and measure, covering several pages with his statistical findings (Journal, 8/20/54). This is only one of many examples of Thoreau's fascination with data-gathering, and yet he repeatedly questions its value, as if he does not know what to make of his own penchant for naturalistic research. At the very least, scientific investigations run the risk of being “trivial and petty,” so perhaps what one should do is “learn science and then forget it” (Journal, 1/21/53 & 4/22/52). But Thoreau is more deeply troubled by the possibility that “science is inhuman,” since objects “seen with a microscope begin to be insignificant,” and this is “not the means of acquiring true knowledge” (Journal, 5/1/59 & 5/28/54). Overall, his position is not that a mystical or imaginative awareness of the world is incompatible with knowledge of measurable facts, but that an exclusive focus on the latter would blind us to whatever aspects of reality fall outside the scope of our measurement. One thing we can learn from all of Thoreau's comments on scientific inquiry is that he cares very much about the following question: what can we know about the world, and how are we able to know it? Although he admires the precision of scientific information, he wonders if what it delivers is always bound to be “something less than the vague poetic” (Journal, 1/5/50). In principle, a naturalistic approach to reality should be able to capture its beauty and significance; in practice, however, it may be “impossible for the same person to see things from the poet's point of view and that of the man of science” (Journal, 2/18/52). In that case, the best we can do is try to convey our intimations of the truth about the universe, and be willing to err on the side of obscurity and excess: “I desire to speak somewhere without bounds; like a man in his waking moment, to men in their waking moments; for I am convinced that I cannot exaggerate enough even to lay the foundation of a true expression… . The words which express our faith and piety are not definite; yet they are significant and fragrant like frankincense to superior natures” (Walden, XVIII). We should not arbitrarily limit our awareness to that which can be described with mathematical exactitude: perhaps the highest knowledge available to us, Thoreau suggests, consists in “a sudden revelation of the insufficiency of all that we called Knowledge before … it is the lighting up of the mist by the sun” (“Walking”). And perhaps this is not a regrettable fact: “At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be infinitely wild, unsurveyed and unfathomed by us because unfathomable” (Walden, XVII). By acknowledging the limits of what we can know with certainty, we open ourselves up to a wider horizon of experience. As one commentator points out, Thoreau's categories are more dynamic than Kant's, since they are constantly being redefined by what we perceive, even as they shape our way of seeing (Peck 1990, 84–85). Every now and then “something will occur which my philosophy has not dreamed of,” Thoreau says, which demonstrates that the “boundaries of the actual are no more fixed and rigid than the elasticity of our imaginations” (Journal, 5/31/53). Since the thoughts of each knowing subject are “part of the meaning of the world,” it is legitimate to ask: “Who can say what is? He can only say how he sees” (11/4/52 & 12/2/46). Truth is radically perspective-dependent, which means that insofar as we are different people we can only be expected to perceive different worlds (Walls 1995, 213). Thoreau's position might be described as perspectival realism, since he does not conclude that truth is relative but celebrates the diversity of the multifaceted reality that each of us knows in his own distinctive way. “How novel and original must be each new man's view of the universe!” he exclaims; “How sweet is the perception of a new natural fact,” for it suggests to us “what worlds remain to be unveiled” (Journal, 4/2/52 & 4/19/52). We may never comprehend the intimate relation between a significant fact and the perceiver who appreciates it, but we should trust that it is not in vain to view nature with “humane affections” (Journal, 2/20/57 & 6/30/52). With respect to any given phenomenon, the “point of interest” that concerns us lies neither in the coolly independent object nor in the subject alone, but somewhere in between (Journal, 11/5/57). Witnessing the rise of positivism and its ideal of complete objectivity, Thoreau attempts “to preserve an enchanted world and to place the passionate observer in the center of his or her universe” (Tauber 2001, 20). It is a noble goal, and one that remains quite relevant in the philosophical climate of the present day.
