FORM IS NOT A QUALITY; BUT A REASON.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
Is form a quality? No: form is a reason. Now what is constituted by (material) substance, and reason? (In the warm body) it is neither what burns, nor what is visible; it is quality. If, however, it be said that combustion is an act emanating from reason, that being hot and white are actualities, we could not find anything to explain quality.
