Describe Hume’s theory of the perception of the mind?
How adequate is Hume’s theory of perception?

  a. Hume’s ultimate aim of his theory of the perception of the mind is to gain certainty through empiricism and a posteriori knowledge. To do this, he first explains what his perception of the mind is. Hume describes perceptions as any content of the mind in which we are conscious of.

There are two different types of impressions; outward and inward. Outward impressions are experiences from the sensations of the brain, they are external whereas inward impressions are feelings experienced and are internal. An example of an outward experience would be punching someone in the face. An example of an inward experience would be feeling relief once punching someone. Hume claims these initiate from ‘inward sentiments’. Impressions are dominant and don’t take any effort to think about. Ideas on the other hand, according to Hume, are a memory of an impression. Hume claims that ideas cannot exist without an initial impression. Their immediacy and strength diminish over time. Ideas are a copy of the original impression and require effort on our part to think about it. Like impressions, ideas are also broken down into two categories; simple and complex. Simple ideas are the result of an impression and we refer to these as memories. An example of a simple idea would be the memory of eating your favourite food at a restaurant. Complex ideas...
