Categorical Proposition and
Immediate Inference Exercises

The first exercise helps with developing understanding the properties and categorical propositions: their forms, qualities, qualities, and distribution statuses for subject and predicate. Practice with Venn diagrams for categorical propositions is provided on a separate sheet.

The second exercise provides practice is distinguishing statements (or propositions) from nonstatements (or propositions).

The next exercise consists of practice with inferences based on the logical relations on the square of opposition: contradiction, contrary, subcontrary, and subalternation.

Problem set four includes the logical relations of further immediate inferences: conversion, obversion, and contraposition.

And the last practice presents practice for working with successive immediate inferences — these involve the use of both the square of opposition inferences and the further immediate inferences.
