| Extension | To ask what is the extension of a concept is to ask, "To what does the concept man refer?" Answer: All the men who have ever lived, who are now living, and who will live in the future. |
| The Relationship between Comprehension and Extension | The greater the comprehension a concept has, the less extension it has; and the more extension it has, the less comprehension. |
