The Different Types of Epistemology

The diagram in the accompanying substack article may be of use to at least some degree in summarising a part of epistemology, as I understand it. David Deutsch follows on from the work mainly initiated by Karl Popper with some supplementary editions by Richard Dawkins among other people. We're going to consider the various intersections and compliments of knowledge with ideas. What is common to all instances of ideas is that they are abstractions which could in principle be communicated and represented in various physical forms. An idea, like knowledge, can be said to be independent of its physical substrate. And we don't have any good explanations as to precisely how this works in a brain.
