Hume’s Epistemology

“Impressions” and “Ideas”:

•Question: Where do our “ideas” come from?
Answer: From various “impressions.” An “impression” is what you have when you are actually experiencing something. When you are eating the apple, you have an impression of its juiciness and tartness. When (later) you remember eating the apple, you have an idea of its juiciness and tartness. Impressions are more vivid .

•The impression lasts only as long as the experience lasts; the idea is “filed away” in your memory.
•Any idea not derived from an impression is bogus!
