Roughly, the idea underlying the first premise is that an individual is often defined as thinking individual and thought can never be separated from consciousness. By consciousness, Locke means that individuals are able to be aware or perceive something. So, the first premise says that consciousness is independent of any other substances. This does not, however, claim that consciousness is able to exist without a body or a mind.&nbsp.Assuming&nbsp.that consciousness is tied to a given body or soul&nbsp.is not necessary. In this sense though, there is still no reason to make the assumption that consciousness is not transferable from one body or even mind to the next.
