Learning philosophy

“The content of your character is your choice. Day by day, what you choose, what you think and what you do is who you become.” ―Heraclitus

At M&M, we are interested in trying to figure out how things work, not affirming our existing beliefs. We prefer consulting primary rather than secondary sources and independent rather than institutional voices. If we encounter uncomfortable truths or the evidence suggests unfashionable ideas may be valid, so be it.

As the host, my aim is to help you better understand how the body & mind work by curating & synthesizing information in a way that yields science-based insights that you can choose to use or disregard in your own life. Taking ownership of your health starts with taking ownership of your information diet.

I am motivated to connect the dots and distill general principles from what I learn, preferring to ask questions and play devil’s advocate to debating or incessantly pushing my own viewpoint.

My beliefs:

Sometimes modern discoveries teach us we must unlearn received wisdom. Other times, modern information overload & historical chauvinism cause us to forget ancient wisdom which stills applies. The framework for learning that I embody is inspired by three Ancient Greek maxims inscribed in the Temple of Apollo at Delphi:

  • “Γνῶθι σεαυτόν” (Know thyself)

  • “Μηδὲν ἄγαν” (Nothing in excess)

  • “Ἐγγύα πάρα δ Ἄτα” (Certainty brings insanity)
