GRADIENT SCALE, 1. the term can apply to anything, and means a scale of condition graduated from zero to infinity. Absolutes are considered to be unobtainable. (Scn 8-8008, p. 104) 2. the tool of infinity-valued logic. It is a tenet of Dn and Scn that absolutes are unattainable. Terms like good and bad,alive and dead, right and wrong are used only in conjunction with gradient scales. On the scale of right and wrong, everything above zero or center would be more and more right, approaching an infinite rightness, and everything below zero or center would be more and more wrong, approaching an infinite wrongness. The gradient scale is a way of thinking about the universe which approximates the actual conditions of the universe more closely than any other existing logical method. (SOS Gloss)
