The Categorical Converter

The Categorial Converter is a visual representation of all possible logical relationships between individual categorical propositions. It may be used to test the validity of an inference from one proposition to another.

In other words, the Categorical Converter represents all possible inferences using the rules of:

  • Contradiction
  • Contrary
  • Subcontrary
  • Subalternation
  • Superalternation
  • Obversion
  • Conversion
  • Transposition
From here, you may view the Categorical Converter. You may also learn how to use it, and finally, learn how it was constructed.
