I didn't state my question clearly but your post triggers an idea. Suppose the x-axis represents a set of balls and the y-axis a set of colors, then a dot at x,y would indicate "ball2 is Red". How to extend this system to represent "ball between box and chair"? Could I suppose 3-axes where each represents the set of all things in a room. Then a dot a x,y,z would indicate what thing is between two other things? Received on Wed Jan 01 2003 - 00:15:34 CET
