I slept none that night; the farther I was from the occasion of my fright, the greater my apprehensions were, which is something contrary to the nature of such things, and especially to the usual practice of all creatures in fear; but I was so embarrassed with my own frightful ideas of the thing, that I formed nothing but dismal imaginations to myself, even though I was now a great way off. Sometimes I fancied it must be the devil, and reason joined in with me in this supposition, for how should any other thing in human shape come into the place? Where was the vessel that brought them? What marks were there of any other footstep? And how was it possible a man should come there? But then, to think that Satan should take human shape upon him in such a place, where there could be no manner of occasion for it, but to leave the print of his foot behind him, and that even for no purpose too, for he could not be sure I should see it — this was an amusement the other way. I considered that the devil might have found out abundance of other ways to have terrified me than this of the single print of a foot; that as I lived quite on the other side of the island, he would never have been so simple as to leave a mark in a place where it was ten thousand to one whether I should ever see it or not, and in the sand too, which the first surge of the sea, upon a high wind, would have defaced entirely. All this seemed inconsistent with the thing itself and with all the notions we usually entertain of the subtlety of the devil.
Abundance of such things as these assisted to argue me out of all apprehensions of its being the devil; and I presently concluded then that it must be some more dangerous creature — viz. that it must be some of the savages of the mainland opposite who had wandered out to sea in their canoes, and either driven by the currents or by contrary winds, had made the island, and had been on shore, but were gone away again to sea; being as loath, perhaps, to have stayed in this desolate island as I would have been to have had them.
While these reflections were rolling in my mind, I was very thankful in my thoughts that I was so happy as not to be thereabouts at that time, or that they did not see my boat, by which they would have concluded that some inhabitants had been in the place, and perhaps have searched farther for me. Then terrible thoughts racked my imagination about their having found out my boat, and that there were people here; and that, if so, I should certainly have them come again in greater numbers and devour me; that if it should happen that they should not find me, yet they would find my enclosure, destroy all my corn, and carry away all my flock of tame goats, and I should perish at last for mere want.
Thus my fear banished all my religious hope, all that former confidence in God, which was founded upon such wonderful experience as I had had of His goodness; as if He that had fed me by miracle hitherto could not preserve, by His power, the provision which He had made for me by His goodness. I reproached myself with my laziness, that would not sow any more corn one year than would just serve me till the next season, as if no accident could intervene to prevent my enjoying the crop that was upon the ground; and this I thought so just a reproof, that I resolved for the future to have two or three years` corn beforehand; so that, whatever might come, I might not perish for want of bread.
How strange a chequer-work of Providence is the life of man! and by what secret different springs are the affections hurried about, as different circumstances present! To-day we love what to-morrow we hate; to-day we seek what to-morrow we shun; to-day we desire what to-morrow we fear, nay, even tremble at the apprehensions of. This was exemplified in me, at this time, in the most lively manner imaginable; for I, whose only affliction was that I seemed banished from human society, that I was alone, circumscribed by the boundless ocean, cut off from mankind, and condemned to what I call silent life; that I was as one whom Heaven thought not worthy to be numbered among the living, or to appear among the rest of His creatures; that to have seen one of my own species would have seemed to me a raising me from death to life, and the greatest blessing that Heaven itself, next to the supreme blessing of salvation, could bestow; I say, that I should now tremble at the very apprehensions of seeing a man, and was ready to sink into the ground at but the shadow or silent appearance of a man having set his foot in the island.
