Most podcasts are available to listen for free. Comedian Ricky Gervais expects fans to pay $15 to hear his latest musings with neuroscientist and philosopher Sam Harris on life as we know it.

All 10 episodes of “Absolutely Mental” Season 2 are now available at absolutelymental.com. The full season costs $14.99; the site also offers a special $19.99 bundle if you buy both S2 and S1, which was released in May.

In the second season, Gervais returns to the hot mic to chat with his favorite smart friend, Harris, in wide-ranging and sometimes heated conversations about what it is to be human. “Absolutely Mental” also has a self-help element, in which the duo discuss how to live longer, how to be smarter and how to be happy. (The podcast also promises to answer the age-old question of whether it’s better to have no knees or no elbows.)

“The response to the first series has been genuinely amazing, so I can’t wait for people to hear the new episodes because I think they’re even better,” Gervais said in a statement. “I’ve even bought a posh microphone. Professional.”

Harris commented, “It has been one of the great privileges of my life to drag myself out of bed each Saturday morning, only to be reminded that — with civilization unravelling by the hour — Ricky Gervais is primarily afraid of spiders.”

Gervais, creator and star of the original British series “The Office,” previously teamed with SiriusXM for a podcast called “Ricky Gervais is Deadly Sirius,” which aired from 2017-19. He is currently in production on the third and final season of Netflix’s “After Life,” which he created, writes, directs and stars in.
