He introduces two possibilities as to the nature of a physical (which we can equate to scientific) theory. The first being that it is an accounting of the reality lying behind a group of data-based laws (those that are empirically determined). The second is that a physical theory is simply an abstract system to come apart and summarize a group of laws.

Taking the first gap (a belief thus far held by many today): this seeks to aim beneath the sensible appearances and picture the reality beneath, which is causing the sensations we experience. However, this presents us with a problem. We only render access to perceptions so how can we hope to find a physical theory that provides a certain explanation of the reality causing these se! nsations?
