Part of a series which began with Fake news and the ethics of belief.
Why am I so interested in what some random bearded Victorian dude thought about anything?
Here is one reason (in three parts):
(i) An important branch of philosophy – epistemology – is concerned with knowledge and belief.
(ii) An important position in epistemology – evidentialism – holds that beliefs should only be based on relevant evidence.1
(iii) Random bearded Victorian dude William Clifford effectively kicked off evidentialism.
