This is an "irregular" ToKCast which is all about a short essay by Popper titled "The Aim of Science". I read parts of the essay and comment on it and compare it to some more recent developments in the philosophy of science. Readings for this - like the paper itself - can be found here: http://www.bretthall.org/the-aim-of-s... The thing about the essay that is amazing is how certain paragraphs are as clear as anything one might say on this topic today: and yet he is breaking the ground in many ways with what he is saying. People struggled until Popper to even make a coherent case for what science was all about let alone how it managed to do it. There are only a few images in this "video" so you can easily get away with listening to the audio only version of this.
