Professor Cora Diamond joins John and Ken to think about what, if anything, could count as sacred anymore. Cora puts forward a working definition of the sacred as the sphere of things that are off limits to human intervention, things towards which we ought to hold an attitude of awe. Actions that interfere with these sacred things are what we call taboo. Ken wants to know what the difference is between taboos based on a recognition of the objectively sacred, and those based on mere ignorance or disgust.

几位听众对着麦克风发表他们的意见和问题。一种是对神圣和禁忌的概念进行进化解释。另一个人想知道，让朋友和家人享受从他的坟墓里长出来的迷幻蘑菇是否违反了神圣。

在节目的最后一部分，我们的主持人考虑神圣与自然之间的联系，禁忌与傲慢之间的联系。例如，戴蒙德教授认为饲养火鸡的方式会阻碍它们的自然行为——行走、性交等等——是对神圣的侵犯。在休谟的时代，许多人认为河流改道是一种亵渎神明的行为，因为这涉及改变上帝的计划。今天的世俗人士可能不会有这种感觉，但他们仍然可能认为陆军工兵部队认为他们可以控制密西西比河是傲慢的(和危险的)。然而，这种认为做某件事就会傲慢到把某人当作不做这件事的理由的感觉吗?它是否具有我们认为神圣的概念应该具有的规范性力量?最重要的是，那些迷幻蘑菇呢?

• The 60-Second Philosopher: (seek to 50:04) Ian Shoales ruminates on the sacred in America. His list includes sacred spaces (mostly where a lot of people died), comic book collections stored in hermetically sealed vaults, and cult classics.
  
• Roving Philosophical Report: (seek to 6:43) Caitlin Esch takes to the streets of Portland to find out about the substance and science of taboos. She learns about the benefits and difficulties of breaking the taboo against having multiple partners from Brian Bloom, the facilitator of a polyamory group. Also, Allison Burns-Glover, a professor of Psychology at Pacific University, talks about the physiological response to seeing someone break a taboo.
