I call our world Fiatland. Not because we name it that way, but to better illustrate its nature to you, my happy readers, who have the privilege of living in the three-dimensional world. Imagine a large sheet of paper on or in whose surface straight lines, triangles, quadrilaterals, pentagons, hexagons, and other shapes move freely, instead of staying fixed in place, yet unable to move up or down out of the sheet, almost like shadows – only constant and with luminous sides. This gives you a fairly accurate impression of my country and my fellow citizens. Ah, until a few years ago, I would have still referred to it as my universe. However, in the meantime, my mind has been opened to higher insights. Thus begins Edwin A. Abbott, who writes under the pseudonym "A Square.".
