_Feb. 9._ The last half of January was warm and thawy. The swift streams were open, and the muskrats were seen swimming and diving and bringing up clams, leaving their shells on the ice. We had now forgotten summer and autumn, but had already begun to anticipate spring. Fishermen improved the warmer weather to fish for pickerel through the ice. Before it was only the autumn landscape with a thin layer of snow upon it; we saw the withered flowers through it; but now we do not think of autumn when we look on this snow. That earth is effectually buried. It is midwinter. Within a few days the cold has set in stronger than ever, though the days are much longer now. Now I travel across the fields on the crust which has frozen since the January thaw, and I can cross the river in most places. It is easier to get about the country than at any other season,—easier than in summer, because the rivers and meadows are frozen and there is no high grass or other crops to be avoided; easier than in December before the crust was frozen. * * * * * Sir John Mandeville says, “In fro what partie of the earth that men dwell, outher aboven or benethen, it seemeth always to hem that dwellen there, that they gon more right than any other folk.” Again, “And yee shulle undirstonde, that of all theise contrees, and of all theise yles, and of all the dyverse folk, that I have spoken of before, and of dyverse laws and of dyverse beleeves that thei have, yit is there non of hem alle, but that thei have sum resoun within hem and understondinge, but gif it be the fewere.” I have heard that there is a Society for the Diffusion of Useful Knowledge. It is said that knowledge is power and the like. Methinks there is equal need of a Society for the Diffusion of Useful Ignorance, for what is most of our boasted so-called knowledge but a conceit that we know something, which robs us of the advantages of our actual ignorance.[127] * * * * * For a man’s ignorance sometimes is not only useful but beautiful, while his knowledge is oftentimes worse than useless, beside being ugly.[128] In reference to important things, whose knowledge amounts to more than a consciousness of his ignorance? Yet what more refreshing and inspiring knowledge than this? How often are we wise as serpents without being harmless as doves! Donne says, “Who are a little wise the best fools be.” Cudworth says, “We have all of us by nature μάντευμά τε (as both Plato and Aristotle call it), a certain divination, presage and parturient vaticination in our minds, of some higher good and perfection than either power or knowledge.” Aristotle himself declares, that there is λόγον τι κρεῖττον, which is λόγον ἀρχή,—(something better than reason and knowledge, which is the principle and original of all). Lavater says, “Who finds the clearest not clear, thinks the darkest not obscure.” * * * * *
