The Ayn Rand Institute has made available a talk I gave on "motivation by love" at the 2019 Objectivist Conferences (OCON).

This talk was for an audience of Ayn Rand fans, so it assumes a context that not all readers of the site will have. But I think it is generally accessible. If it raises questions, email me! There is much more on this topic on this site and in the Thinking Lab.
