The speech I gave to The Ethical Society of St. Louis on The Ethics of Polyamory is available as a podcast. Huge thanks to The Ethical Society for the opportunity and for making the recording available online. One important note: further research has shown me that the numbers I gave on infidelity are probably closer to 25% than 50%, so adjust your expectations accordingly.
From the Ethical Society’s website: This talk will discuss polyamory (consensual non-monogamy) as a type of relationship structure. Topics include the myriad of non-monogamous relationship structures, the ethics of polyamory, negotiation and consent, time management, how polyamorous structures can exist in an ostensibly monogamous world, and a personal perspective on a polyamorous life.
