The workshops include of a prior presentation of the topic by myself on YouTube. The meeting itself consists of a brief review of the topic followed by questions and discussion. The weekly topic is posted a week before the event, together with a suggested reading from my work The Pursuit of Value, available through Amazon Books or myself. Transcripts of the Youtube presentation are available by email.

THIS WEEK: The nominalist/realist debate is about what properties exist independently in the world and what properties are products of the mind. Locke distinguishes between primary qualities in the world and secondary qualities like taste and colour. Kant holds that time and space are products of the mind, explicable in terms of mathematics. But is even mathematics a product of the mind, as held by Heidegger and Wittgenstein? And can mathematics and number be explained through the structures of consciousness? But how then can mathematics make correct predictions about future discoveries in physics? Reading: The Pursuit of Value, Ch. 6, Scn. xi.
