The University Discussion - Anthony Flew, Assertions And Qualification - Sadler's Lectures
This lecture discusses key ideas from the mid-20th century symposium on falsification and theology called the "University Discussion" which can be found in the volume New Essays in Philosophical Theology
It focuses specifically on Anthony Flew's first contribution to the discussion, which starts with a revised version of John Wisdom's parable of the invisible gardener from his article Gods. Flew argues that much modern theological discourse, in so far as it consists in genuine assertions, risks "death by a thousand qualifications".

Karl Popper, Towards A Rational Theory Of Tradition - How Science Develops
This lecture discusses key ideas from the 20th century philosopher Karl Popper's article "Towards A Rational Theory Of Tradition", found in his book Conjectures and Refutations.
It focuses specifically on his discussion of how science develops historically. Popper does not think that observation and the "scientific method" taught in classes and textbooks is really at the core of what science is and how it develops. Instead, what sustains it is a critical tradition that involves discussion about whether accounts are accurate, coherent, and defensible, along with revision of accounts in light of that discussion
