Origin of Ideas

According to Hume thier is a distinction between impressions and ideas. Hume says that ideas are the weaker form of impressions. They are lacking something that impressions have, they are less vivacious. Impressions according to Hume are sensations and ideas are memories and ideas. Hume gives the example of a person eating an orange. The impressions of eating the orange, taste, feel and smell are stronger then some one imagining eating an orange. Hume then goes on to say that both the color red and anger are considerend impressions (everything we hear, see, touch, smell, feel and love) and ideas arise when we reflect back on those impressions.
