The Logical Structure of Objectivism

A collaboration between David Kelley and William Thomas, based on a series of lectures originally composed by Dr. Kelley, it traces out the logical connections among the various principles of Objectivism. It uses an argument diagramming technique featured in Dr. Kelley's logic text, The Art of Reasoning, to show relations within the system and to highlight the dependence, at every point in the philosophy, on factual evidence. The book is meant to provide students of Objectivism with a road-map to the system, and to provide interested intellectuals with a clear and comprehensible exposition of this distinctive philosophic perspective.

In 1999, William Thomas offered a course based on this project at TOC's Summer Seminar at University of Vermont in Burlington. He also discussed, along with Dr. Kelley, the methodology of the project at the first annual Advanced Seminar held there. For those lectures, the authors prepared a draft of the book, dubbed the "Beta" version, and offered it for comments to a limited number of students and scholars.

The "LSO" is currently being revised by Kelley and Thomas.

In the meantime, as a resource and to provide the background against which the revisions are being composed, Thomas and Kelley have posted their 1999 "Beta" draft (at right, saved as individual chapters in Adobe PDF format). Please note that the "Beta" draft is not being offered for comments, except of the most general character.
