Document Summary
[1] hume presents the fundamentals of his theory of ideas in enquiry 2 the mental mechan- ics that support his new science of the mind. He begins with the following three claims: (t1) all perceptions are either (a) impressions, or (b) ideas. (t2) sensing and sentiment produce only impressions, whereas thinking produces only ideas. (t3) all ideas are copies" of impressions. Impressions are distinguished from ideas in being more forceful and lively in themselves; it roughly matches up with the distinction between feeling and thinking, present experience and non-present experience (e. g. memory). The last of these, (t3), is known as the copy thesis because it links impressions and ideas. Hume offers two arguments for (t3) in 2. 6 7; the rst argument depends on a distinction that requires a restatement of both theses put forward so far. Hume now says that ideas may be either simple or complex.
