Note 23 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
Let a piece of red-hot iron be taken, every part of which is heavy, hard, hot, &c. Not one of these attributes can be confounded with another, or with the iron itself, but each one runs through the whole iron. Now, if each attribute is due to the presence of some material producing it, there is no avoiding the conclusion that there must exist in the iron, and in each part of it, as many various materials as there are attributes, without any one of them losing its own identity. ↑
