| Paragraph 1 |
Ignorance-defined not as the negation of knowledge but as a positive state of mind-is error produced by inference. |
| Paragraph 2 |
(1) Let us first consider propositions asserting a predicate's immediate connexion with or disconnexion from a subject. |
| Paragraph 3 |
Error of attribution, then, occurs through these causes and in this form only-for we found that no syllogism of universal attribution was possible in any figure but the first. |
| Paragraph 4 |
(c) It may occur when both premisses are false; |
| Paragraph 5 |
(d) It is also possible when one is false. |
| Paragraph 6 |
In the second figure the premisses cannot both be wholly false; |
| Paragraph 7 |
It is thus clear that in the case of atomic propositions erroneous inference will be possible not only when both premisses are false but also when only one is false. |
