Pounamu Pounamu Pounamu refers to several types of hard, durable and highly valued nephrite jade, bowenite, or serpentinite stone found in southern New Zealand. Pounamu is the Māori name. These rocks are also generically known as "greenstone" in New Zealand English. There are two systems for classifying pounamu. Geologically, the rock falls into the three categories named above, but Māori classify pounamu by appearance. The main classifications are "kawakawa", "kahurangi", "īnanga", and "tangiwai". The first three are nephrite jade, while "tangiwai" is a form of bowenite. In modern usage "pounamu" almost always refers to nephrite jade. Pounamu is generally found in
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
