Primary Texts in Collins Library

Print copies of philosophical texts can be located via the Collins Library Primo Search.

Scholarly Editions
Whenever possible, you should use scholarly editions of philosophical texts. A scholarly edition of a text typically will present and discuss variant versions; provide historical, cultural and linguistic context; and delineate the history of scholarly approaches to that text. Most scholarly editions will have an editor (or editors) and will be published by a university press (see catalog example below).

Kant's Critique of Pure Reason

Kant editor and translator

Kant publisher, Cambridge University Press

English translations of philosophical texts can differ markedly. Always use the translation your professor recommends.

Puget Sound Archives & Special Collections, Philosophy

The Archives & Special Collections collects, preserves, and makes available primary source material documenting life at the University as well as collections representing regional, national and international issues.

The John D. Regester Collection on Albert Schweitzer, 1924-1974, documents Regester's research on Albert Schweitzer (1875-1965), a medical missionary, philosopher, and Nobel Peace Prize winner (1952) who operated a hospital in Lambaréné, Gabon, for 45 years.

Descartes, René, Les principes de la philosophie, 1659.

Public Domain Texts

Google Books will help you find online versions of older philosophy texts that are in the public domain (out of copyright). These texts will not include the most up-to-date scholarly annotations. Be especially careful if you are using an older translation; some nineteenth-century translators edited content without letting the reader know.
