 | | To these are to be added the Agent (Efficient Cause) and the End (Final Cause); but as the efficiency and finality are to be reduced, in ultimate analysis, to Form, we have in the physical order two ultimate principles of Being, namely, Matter and Form. |
 | | The Formal Cause, that according to which the statue is made, is the idea existing in the first place as exemplar in the mind of the sculptor, and in the second place as intrinsic, determining cause, embodied in the matter. |
 | | This is true not only in the world of living things, in which, for example, the oak is potentially contained in the acorn, but also in the inanimate world in which heat, for instance, is potentially contained in water, and needs but the agency of fire to be brought out into actuality. |
