Hello, and welcome to New Books and Philosophy, a podcast channel with the New Books Network. I'm Carrie Figdor, Associate Professor of Philosophy at the University of Iowa. I'm co-host of the channel, along with Robert Talese, Professor of Philosophy at Vanderbilt University. Together, we bring you conversations with philosophers about their new books, drawing from a wide range of areas of contemporary philosophical inquiry. Today's interview is with Jonathan Birch. associate professor at the London School of Economics. His new book, The Philosophy of Social Evolution, is just out from Oxford University Press. It seems to go against evolutionary theory for an individual to give up its own chances at reproducing in order to increase the fitness of others.
Yet social behavior is found throughout nature, from bacteria and social insects to wolves, whales, and of course human beings. So what makes self-sacrifice to any degree even possible, given that self-interested behavior is the default? In his new book, Birch critically examines the conceptual foundations of social evolution theory, considering debates about kin selection versus group selection, cultural as well as genetic transmissible bases of inheritance, and inclusive versus neighbor-modulated fitness. He also discusses the view of multicellular organisms as societies of cells and extends the concept of genetic relatedness to include cultural relatedness by means of common cultural traits. Let's turn to the interview.
Hello, Jonathan Birch. Welcome to New Books in Philosophy. Hi,
Carrie.
I'm glad to have you here to talk about your book, The Philosophy of Social Evolution. I was just thinking, I've done books on the philosophy of social ontology, you know, what objects
are
social and institutions, which is a metaphysical thing. And then I've also done on social cognition, which is about, you know, how we understand things. minds and behavior of others. And this is a whole different sort of aspect of the social, you might say, which is how we, how we and, you know, across, you know, throughout the biological world, Different forms of insomniac cooperative behavior have developed through evolution.
Yeah, how social behavior evolves.
Yeah. So this is, you know, and of course the pressing question, one of the pressing questions today is, well, just has it really evolved all that much? It seems we're not quite there. As cooperative as we might be.
We're not as good as ants.
No. So before we get into the book itself, maybe you could say a bit about your background and how you came to write this book.
My background, yeah, I mean, my first degree was in natural sciences at the University of Cambridge, and then I moved in to history and philosophy of science from there.
