 In HJC, she considers Hume’s answer to the question, how do we know about historical events? For example, how do we know that Caesar was killed on the Ides of March? How do we even know that Caesar was a real man, and not a mythical figure like Electra? Hume’s answer was essentially that you perceive or remember someone (perhaps your school teacher) telling you about Caesar, and you next infer the cause of that – namely, that someone told them – and so on, until you infer that there were eyewitnesses in the Senate, who then witnessed Caesar’s death. You thus infer the original event through a series of causes terminating in something you perceive or remember perceiving.
