J. R. Lucas on the other hand is one of those philosophers who brings expertise to every subject he approaches. This is partially because he takes philosophy to be a way of life rather than a method to win arguments. So he has written on logic, the philosophy of mathematics, the philosophy of science, the philosophy of mind, the philosophy of religion, political philosophy, the history of philosophy, ethics, metaphysics, etc. You can see a bibliography of his publications here. A list of his books shows his diversity:
The Principles of PoliticsThose are the books he's written by himself. He has also written books with other authors:
The Concept of Probability
The Freedom of the Will
A Treatise on Time and Space
Democracy and Participation
Freedom and Grace
Space, Time and Causality
The Conceptual Roots of Mathematics
Economics as a Moral Science
Reason and Reality
The Nature of MindAs far as I'm concerned, Lucas is one of the most important and under-appreciated philosophers of our day. He has written on philosophical subjects so diverse, and yet with a mastery that I could never achieve if I focused my life on just one of them. For one thing, the man thoroughly understands Gödel's Incompleteness Theorems. These theorems are so notoriously complex that I suspect there's only a few hundred people alive who understand them. Yet not only does Lucas understand them, he is able to show that they render strong artificial intelligence and all forms of physical determinism impossible. If I spent my entire life on Gödel's theorems I still wouldn't be able to interact with them as thoroughly as Lucas.
The Development of Mind
Spacetime and Electromagnetism
An Engagement with Plato's Republic
Fortunately Lucas has posted excerpts from several of his books online, as well as most of his published articles. You can read his Reason and Reality in its entirety, as well as Ethical Economics. He is putting another book on the subject, Economics as a Moral Science, online as he writes it. so far he has chapters 1 ; 2 ; 3 ; 4 ; 5 ; 6 ; 7; conclusion ; and two appendices here and here. He has also posted several chapters from his The Conceptual Roots of Mathematics online: chapters 2 ; 4 ; 7 ; 8 ("The Implications of Gödel's Theorem") ; 9a (which replaces his previous chapter 13) ; 9b ; 10a ; and 14. An Engagement with Plato's Republic, co-written with the late great Basil Mitchell, has the introduction and chapters 1 ; 3 ; and 10 posted online.
I'm linking to all of these to invite you to join me in being a student of Lucas. Philosophy students are going to be writing dissertations on him 500 years from now.
