Conversion

June 8, 2011 1 Comment

Conversion is a transition in categorical (Aristotlean) logic.  It involves only one step:

  1. Switch the subject and predicate terms.

If, for example, one asserts the I-Type sentence ‘Some 4-chan users are trolls’, a conversion would:

  1. switch ’4-chan users’ and ‘trolls’ in the sentence, producing: ‘Some trolls are 4-chan users’.
