A Week on the Concord and Merrimack Rivers Henry David Thoreau (novels in english .TXT) 📖

poet uses the results of science and philosophy, and generalizes their widest deductions.

The process of discovery is very simple. An unwearied and systematic application of known laws to nature, causes the unknown to reveal themselves. Almost any mode of observation will be successful at last, for what is most wanted is method. Only let something be determined and fixed around which observation may rally. How many new relations a foot-rule alone will reveal, and to how many things still this has not been applied! What wonderful discoveries have been and may still be made, with a plumb-line, a level, a surveyor’s compass, a thermometer, or a barometer! Where there is an observatory and a telescope, we expect that any eyes will see new worlds at once. I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact. A discovery is made, and at once the attention of all observers is distracted to that, and it draws many analogous discoveries in its train; as if their work were not already laid out for them, but they had been lying on their oars. There is wanting constant and accurate observation with enough of theory to direct and discipline it.

But, above all, there is wanting genius. Our books of science, as they improve in accuracy, are in danger of losing the freshness and vigor and readiness to appreciate the real laws of Nature, which is a marked merit in the ofttimes false theories of the ancients. I am attracted by the slight pride and satisfaction, the emphatic and even exaggerated style in which some of the older naturalists speak of the operations of Nature, though they are better qualified to appreciate than to discriminate the facts. Their assertions are not without value when disproved. If they are not facts, they are suggestions for Nature herself to act upon. “The Greeks,” says Gesner, “had a common proverb (Λαγος καθευδον) a sleeping hare, for a dissembler or counterfeit; because the hare sees when she sleeps; for this is an admirable and rare work of Nature, that all the residue of her bodily parts take their rest, but the eye standeth continually sentinel.”

Observation is so wide awake, and facts are being so rapidly added to the sum of human experience, that it appears as if the theorizer would always be in arrears, and were doomed forever to arrive at imperfect conclusions; but the power to perceive a law is equally rare in all ages of the world, and depends but little on the number of facts observed. The senses of the savage will furnish him with facts enough to set him up as a philosopher. The ancients can still speak to us with authority, even on the themes of geology and chemistry, though these studies are thought to have had their birth in modern times. Much is said about the progress of science in these centuries. I should say that the useful results of science had accumulated, but that there had been no accumulation of knowledge, strictly speaking, for posterity; for knowledge is to be acquired only by a corresponding experience. How can we know what we are told merely? Each man can interpret another’s experience only by his own. We read that Newton discovered the law of gravitation, but how many who have heard of his famous discovery have recognized the same truth that he did? It may be not one. The revelation which was then made to him has not been superseded by the revelation made to any successor.

We see the planet fall,
And that is all.

In a review of Sir James Clark Ross’s Antarctic Voyage of Discovery, there is a passage which shows how far a body of men are commonly impressed by an object of sublimity, and which is also a good instance of the step from the sublime to the ridiculous. After describing the discovery of the Antarctic Continent, at first seen a hundred miles distant over fields of ice⁠—stupendous ranges of mountains from seven and eight to twelve and fourteen thousand feet high, covered with eternal snow and ice, in solitary and inaccessible grandeur, at one time the weather being beautifully clear, and the sun shining on the icy landscape; a continent whose islands only are accessible, and these exhibited “not the smallest trace of vegetation,” only in a few places the rocks protruding through their icy covering, to convince the beholder that land formed the nucleus, and that it was not an iceberg;⁠—the practical British reviewer proceeds thus, sticking to his last, “On the 22nd of January, afternoon, the Expedition made the latitude of 74° 20′ and by 7h p.m., having ground (ground! where did they get ground?) to believe that they were then in a higher southern latitude than had been attained by that enterprising seaman, the late Captain James Weddel, and therefore higher than all their predecessors, an extra allowance of grog was issued to the crews as a reward for their perseverance.”

Let not us sailors of late centuries take upon ourselves any airs on account of our Newtons and our Cuviers; we deserve an extra allowance of grog only.

We endeavored in vain to persuade the wind to blow through the long corridor of the canal, which is here cut straight through the woods, and were obliged to resort to our old expedient of drawing by a cord. When we reached the Concord, we were forced to row once more in good earnest, with neither wind nor current in our favor, but by this time the rawness of the day had disappeared, and we experienced the warmth of a summer afternoon. This change in the weather was favorable to our contemplative mood, and disposed us to dream yet deeper at our oars, while we floated in imagination
