In the previous episode, Bruce pointed out an apparent contradiction between Deutsch's criteria for knowledge as 'adapted information that causes itself to remain so' and his example of the 'walking robot algorithm' which is a case of adapted information causing itself to remain so but that Deutsch doesn't consider to be knowledge. This time we consider if we can eliminate the 'walking robot algorithm' from being considered 'knowledge' using Deutsch's and Marletto's Constructor Theory of Knowledge. Does the Constructor Theory of Knowledge save the 'two sources hypothesis'? (i.e. the hypothesis that there are only two sources of knowledge: biological evolution and human ideas) --- Send in a voice message: https://podcasters.spotify.com/pod/show/four-strands/message Support this podcast: https://podcasters.spotify.com/pod/show/four-strands/support
