$title = "Using the Categorical Converter - 1"; //
The letters at the top point to every proposition
()
straight below them. They indicate the four
major types of categorical proposition:
A Universal Affirmative
(All S are P)
E Universal Negative
(No S are P)
I Particular Affirmative
(Some S are P)
O Particular Negative
(Some S are not P)
The S and P represent categories. For example, S may represent Dogs while P may represent Mammals.
For any category, we can imagine the opposite of that category. So, for example, if we can imagine Dogs, we can imagine non-Dogs. Where S stands for Dogs, nS stands for non-Dogs.
