In the middle of these cogitations, apprehensions, and reflections, it came into my thoughts one day that all this might be a mere chimera of my own, and that this foot might be the print of my own foot, when I came on shore from my boat: this cheered me up a little, too, and I began to persuade myself it was all a delusion; that it was nothing else but my own foot; and why might I not come that way from the boat, as well as I was going that way to the boat? Again, I considered also that I could by no means tell for certain where I had trod, and where I had not; and that if, at last, this was only the print of my own foot, I had played the part of those fools who try to make stories of spectres and apparitions, and then are frightened at them more than anybody.
