Translated by Donald Rutherford 1. Matter considered in itself, i.e. bare matter, is constituted from antitypy and extension. I call antitypy that attribute through which matter is in space.
Extension is continuation through space or continuous diffusion through place.
And so, as long as antitypy is continuously diffused or extended through place and nothing else is assumed, there arises matter in itself, or bare matter. The modification or variation of antitypy consists in variation of place. The modification of extension consists in variation of magnitude and shape. From this it is obvious that matter is something merely passive, since its attributes and the variation of these involve no action. And insofar as we consider in motion only variation of place, magnitude and shape we consider nothing there that is not merely passive.
