Nephrite Nephrite can be found in a translucent white to very light yellow form which is known in China as "mutton fat" jade, in an opaque white to very light brown or gray which is known as "chicken bone" jade, as well as in a variety of green colors. Western Canada is the principal source of modern lapidary nephrite. Nephrite jade was used mostly in pre-1800 China as well as in New Zealand, the Pacific Coast and Atlantic Coasts of North America, Neolithic Europe, and southeast Asia. The name "nephrite" is derived from "lapis nephriticus", which in turn is derived from
Theory of forms own particulars and not to those of other Forms. For example, there is no Form Not-Greek, only "particulars" of Form Otherness that somehow "suppress" Form Greek. Regardless of whether Socrates meant the particulars of Otherness yield Not-Greek, Not-tall, Not-beautiful, etc., the particulars would operate specifically rather than generally, each somehow yielding only one exclusion. Plato had postulated that we know Forms through a remembrance of the soul's past lives and Aristotle's arguments against this treatment of epistemology are compelling. For Plato, particulars somehow do not exist, and, on the face of it, "that which is non-existent cannot be known". See
