Extending Intuitionistic Logic with Subtraction

“Extending Intuitionistic Logic with Subtraction,” Notes, 1997.

Ideas on the extension of intuitionistic propositional and predicate logic with a ‘subtraction’ connective, Galois connected with disjunction, dual to the implication connective, Galois connected with conjunction. Presented to an audience at Victoria University of Wellington, July 1997. I like this material, but it does not contain any ideas not accessible elsewhere, so it won’t be published anywhere other than here.

Start at the home page—a summary of the site. The left column is news, archived on the news archive page. The central column is for photos, archived on the occasional photos page. The right column contains recent items from the writing page, which lists my publications. These are also categorised by topic. You can follow my links at my account on delicious and occasional short snarky remarks at @consequently on twitter.

Thought

In masculine hands logic is often a form of violence, a sly kind of tyrrany.
