Against these notions is the same sense of finality that opposes all advance. It's why we rate acceptance as a better adaptation than belief. Opposing us is the strong belief that, as to inter-planetary phenomena, virtually everything has been found out. Sense of finality and illusion of homogeneity. But that what is called advancing knowledge is violation of the sense of blankness. A drop of water. Once upon a time water was considered so homogeneous that it was thought of as an element. The microscope--and not only that the supposititiously elementary was seen to be of infinite diversity, but that in its protoplasmic life there were new orders of beings. Or the year 1491--and a European looking westward over the ocean--his feeling that that suave western droop was unbreakable; that gods of regularity would not permit that smooth horizon to be disturbed by coasts or spotted with islands. The unpleasantness of even contemplating such a state--wide, smooth west, so clean against the sky--spotted with islands--geographic leprosy. But coasts and islands and Indians and bison, in the seemingly vacant west: lakes, mountains, rivers-- One looks up at the sky: the relative homogeneity of the relatively unexplored: one thinks of only a few kinds of phenomena. But the acceptance is forced upon me that there are modes and modes and modes of inter-planetary existence: things as different from planets and comets and meteors as Indians are from bison and prairie dogs: a super-geography--or celestiography--of vast stagnant regions, but also of Super-Niagaras and Ultra-Mississippis: and a super-sociology--voyagers and tourists and ravagers: the hunted and the hunting: the super-mercantile, the super-piratic, the super-evangelical. Sense of homogeneity, or our positivist illusion of the unknown--and the fate of all positivism. Astronomy and the academic. Ethics and the abstract. The universal attempt to formulate or to regularize--an attempt that can be made only by disregarding or denying. Or all things disregard or deny that which will eventually invade and destroy them-- Until comes the day when some one thing shall say, and enforce upon Infinitude: "Thus far shalt thou go: here is absolute demarcation." The final utterance: "There is only I." In the _Monthly Notices of the R.A.S._, 11-48, there is a letter from the Rev. W. Read: That, upon the 4th of September, 1851, at 9:30 A.M., he had seen a host of self-luminous bodies, passing the field of his telescope, some slowly and some rapidly. They appeared to occupy a zone several degrees in breadth. The direction of most of them was due east to west, but some moved from north to south. The numbers were tremendous. They were observed for six hours. Editor's note: "May not these appearances be attributed to an abnormal state of the optic nerves of the observer?"
