Reading 6.2 goes over John Locke's account of how we get knowledge of the external world. Explain his causal theory of perception, and then explain Berkeley's objection to Locke's view (6.3). Berkeley's objection to Locke leads to Berkeley's support of a view called subjective idealism. Explain what this view is and why Berkeley believes it to be the correct view of reality and knowledge. Can you come up with an objection to Berkeley's idealism or do you think he is correct that idealism is completely consistent with all the knowledge that we have?
John Locke says that anything which we do not know may be a subject of knowledge for us. We gain various stimulus from our surroundings. These stimulus are obtained through our sense organs. These sensations are interpreted by our brain.
Various ideas may also generate through the ideas of reflection. When we see something then we develop certain idea about that object. We develop certain perceptions and compare those perceptions with our previous experiences.
Subjective idealism says that our mind imparts major role in determining the existence of something. Everything that exists depend on the mental status. In other words, subjective idealism says that matter exists in independent form. It remains independent from human's perception.
This may seem to be true for values and eternal characteristics. It can not be claimed true for physical objects. Our senses play important role in interaction with our surroundings. Subjective idealism seems to be fit for belief systems only.
Suppose if someone says that he/she can save the world from natural calamities then it is basically related with faith and belief. Physically it is not possible for a single person. Hence both Locke's account of knowledge and Berkeley's subjective idealism; both are correct but in different different contexts.
