You are not autonomous. You are not an island unto yourself. You, my friend, are a social construct. The “self” you haul around — that yammering voice in your head — was entirely shaped by your relationships and social interactions. That may be upsetting for "you" to hear. But our guest today, Brian Lowery, prefers to see it as pleasantly humbling because if you can learn to let go of the idea that you have an essential self, you can embrace a more expansive view of who you are and who you can be. Brian Lowery is a professor of organizational behavior at the Stanford Graduate School of Business. His new book is “Selfless: The Social Creation of ‘You.’” --- • We just released an original audiobook written and read by Steven Johnson. It's called "Immortality: A User's Guide," and you can download it now!

Last month, longtime New Yorker staff writer Michael Specter released a brand new audiobook with our friends at Pushkin. It’s called “Higher Animals: Vaccines, Synthetic Biology, and the Future of Life,” and it’s an inspiring account of the emerging field of synthetic biology — a field where scientists combine chemistry, engineering, and computer science to develop new drugs and therapies for treating diseases of all sorts. This month, Steven Johnson, a frequent guest on this show and a contributing writer for The New York Times Magazine, is publishing a brand new audiobook of his own. It’s called “Immortality: A User’s Guide,” and it was produced by ... us! (You can get a copy here.) The premise is this: we might well be on the cusp of a revolution in the science of aging and we are not prepared for the consequences. You can see the overlaps, right? So we decided to get Steven and Michael on the horn to talk about breakthrough technologies, radical life extension, and the future of our species.
