SECTION II
Distinguishing between thoughts/ideas and impressions
Ideas: feelings that we RECALL or do not directly experience in the present. This includes, for eg, recalling feelings of anger from the past or trying to perceive someones feelings other than your own. if someone says that they are sad, you cant feel this sadness however you are able to assume how said person maybe feeling. Ideas are therefore very vague feelings. /expressions etc. They are constructed from past impressions.
Impressions: what we are able to perceive in the present using our own senses.
