Hume draws a distinction between impressions and thoughts or ideas (for the sake of consistency, we will refer only to "ideas" from here on). Impressions are lively and vivid perceptions, while ideas are drawn from memory or the imagination and are thus less lively and vivid..
Beside this, what is an impression according to Hume?
Impressions include sensations as well as desires, passions, and emotions. Ideas are “the faint images of these in thinking and reasoning” (T 1.1. 1.1/1). He thinks everyone will recognize his distinction, since everyone is aware of the difference between feeling and thinking.
Furthermore, what's the primary difference between ideas and impressions? Impressions come through our senses, emotions, and other mental phenomena, whereas ideas are thoughts, beliefs, or memories that we connect to our impressions. We construct ideas from simple impressions in three ways: resemblance, contiguity, and cause and effect.
Keeping this in consideration, how does Hume compare thought and sensation?
The only difference that Hume sees between impressions and ideas is their degree of force and liveliness, or force and vivacity. Impressions are more forceful and lively than ideas: for example, actually feeling a pain is more forceful and lively than merely thinking about a pain.
Why is the distinction between impressions and ideas important to Hume's philosophy?
The distinction between impression and idea is important to Hume because it is his epistemic tool, the basis for his empiricism. Ideas are mental reconstructions of impressions, but they are incomplete as is clear from their lack of fidelity and lack of sensations that were part of the impressions they resemble.
