No, I have already said it elsewhere. This earth has had all the exoticism washed out of it. If in a hundred years we have not established contact with some other planet (but we will), or, next best, with the earth's interior, humanity is finished. There is no longer a means of living, we explode, we go to war, we perpetrate evil of all sorts; we are, in a word, incapable of remaining any longer on this rind. We are in mortal pain; both from the dimensions as they now stand, and from the lack of any future dimension to which we can turn, now that our tour of the earth has been done to death. (These opinions, I know, are quite sufficient to have me looked down upon as a mind of the fourth order.)
