For our summer 2013 activities we will be considering some short subjects, say 1-4 sessions each, and will experiment with some in-group audio and video presentations.
This is a 30 minute DVD video lecture that is fundamentally about epistemology and objective evidence. We will view and discuss this lecture at the meeting. No meeting preparation is required.
Evidence and the Nature of Science, the fourth from a 48 lecture course titled Big History: The Big Bang, Life on Earth, and the Rise of Humanity by Professor David Christian.
Here is the lecture leader: "Why should we trust the claims of science about events in the distant past? This lecture lays some ground rules about evidence for proving scientific claims and describes how new dating techniques have allowed scientist to peer further back into the past than previously thought possible."
This lecture does a very good job of presenting a broad range of epistemological issues in simple, non-technical terms.
The course is produced by The Teaching Company, and just for reference here is a link to the Big History course's home page.
