Absolute threshold -- the minumum intensity of a stimulus that one can detect. Difference threshold -- the minimum difference in intensity between two stimuli that one can detect.
Fechner called the difference threshold by a different name: the just noticeable difference, or JND. Fechner simply assumed that, psychologically speaking, all JNDs seem like the same amount of change in stimulus intensity. For example when lifting a 100 gram weight, one JND = 1/50th of 100 = 2 grams.
