A Compendium of Ockham's Teachings: A Translation of the Tractatus de Principiis Theologiae

Ockham's two great principles were the Principle of Divine Omnipotence and the Principle of Parsimony: Plurality is never to be posited without necessity. The Tractatus takes all of Ockham's views and explains them as related to, or consequences of, the two principles - 167 from the Principle of the Divine and 81 from the Principle of Parsimony.

The translator's (Julian Davies) Introduction offers some helpful hints for reading, and it explains and illustrates the relationship between the two principles. A Glossary of technical terms and Bibliography are included. Footnotes reference English translations of works of Ockham where such exist.
