Enneads VI.3: Plotino's Own Sense-Categories
Quantity Admits of Contraries (Polemic Against Aristotle)
12. It must therefore be admitted that quantity admits of contraries. Even our thought admits of contraries when we say “great” and “small,” since we then conceive of contraries, as when we say, “much and little”; for much and little are in the same condition as great and small. Sometimes it is said, “At home there are many people,” and by this is intended a (relatively) great number; for in the latter case it is a relative. Likewise it is said, “There are few people in the theatre,” instead of saying, “there are less people,” (relatively); but when one uses the word “many” a great multitude in number must be understood.
