Friends and Fans — I have retired from my work as a public intellectual, so Philosophy in Action is on indefinite hiatus. Please check out the voluminous archive of free podcasts, as well as the premium audio content still available for sale. My two books — Responsibility & Luck: A Defense of Praise and Blame and Explore Atlas Shrugged — are available for purchase too. Best wishes! — Diana Brickell (Hsieh)


  • Q&A: The Relationship between Philosophy and Science: 21 Dec 2014, Question 1
  • Question: What is the proper relationship between philosophy and science? People commonly assert that science proves that the traditional claims of philosophy are wrong. For example, they'll say that quantum mechanics proves that objective reality and causality are just myths and that psychology experiments disprove free will. In contrast, other people claim that philosophy is so fundamental that if any claims of science contradict philosophical principles, then the science must be discarded as false. Hence, for example, they say that homosexuality cannot possibly be genetic, whatever science says, since philosophy tells us that people are born "tabula rasa," including without any knowledge of "male" versus "female." So what is the proper view of the relationship between philosophy and the sciences? Does either have a veto power over the other? Is science based on philosophy or vice versa?

  • Q&A: Faith in Reason: 19 Jan 2014, Question 1
  • Question: Does being rational mean having faith in reason? I'm a high school student in a religious school. Many of my classmates claim that my belief in a knowable reality, science, and reason is merely a form of faith. So how can a person validate his own reason and senses? How can a person know that they are reliable means of knowing reality – unless he uses them and thereby engages in circular reasoning? My classmates claim that God is the only way out of this puzzle: God checks our reasoning by verifying and opposing our various conclusions. How can I respond to their arguments effectively?

  • Q&A: The Objectivity of Color Concepts: 14 Jul 2013, Question 4
  • Question: Are concepts of color objective? Given that people from different cultures conceptualize colors differently, I don't see how concepts of color – or at least the demarcation of colors – can be objective. For example, in English, the colors "green" and "blue" have different names because they refer to different concepts. In Japanese, however, the word "aoi" can refer to either light green or blue: they don't draw a distinction between them. Similarly, English speakers refer to both the sky and a sapphire as "blue." But in Italian this is not the case: the word "blu" only refers to dark blue, and the sky is the distinct color of "azzuro." Do such cultural differences cast doubt on the claim that concepts of color are objective?
