And now I began to apply myself to make such necessary things as I found I most wanted, particularly a chair and a table; for without these I was not able to enjoy the few comforts I had in the world; I could not write or eat, or do several things, with so much pleasure without a table: so I went to work. And here I must needs observe, that as reason is the substance and origin of the mathematics, so by stating and squaring everything by reason, and by making the most rational judgment of things, every man may be, in time, master of every mechanic art. I had never handled a tool in my life; and yet, in time, by labour, application, and contrivance, I found at last that I wanted nothing but I could have made it, especially if I had had tools. However, I made abundance of things, even without tools; and some with no more tools than an adze and a hatchet, which perhaps were never made that way before, and that with infinite labour. For example, if I wanted a board, I had no other way but to cut down a tree, set it on an edge before me, and hew it flat on either side with my axe, till I brought it to be thin as a plank, and then dub it smooth with my adze.
