We discussed the first week of the Coursera course from Edinburgh University “Philosophy and the Sciences: Introduction to the Philosophy of Physical Sciences.” ​ www.coursera.org/learn/philosophy-physical-sciences This was a return to some key concepts in philosophy of science: Popper’s Falsification, Underdetermination, and Kuhn’s proposition that “normal” science is conducted within the limits of the currently accepted paradigm. Thes ideas are presented as a preliminary to the project of the course which is to show that Cosmology is a science. We discussed the concepts and the value of the scientific approach to many problems at many levels of our condition today. These built on videos we watched: Michaela Massimi’s lecture to the Royal Society on why science matters (she is one of the course presenters) and some thoughts of the late Daniel Dennett on these issues.
