The post you're about to read is the beginning of a large rant I'm hoping to complete sometime in the near future. The idea for this topic came to me while reading the "Concept of Existence" thread.
***
In order to stop ourselves from falling into philosophical pitfalls (how do we really know anything?) you have to first accept axiomatic principles about objective reality, or else we end up with an "anything goes" type of mindset (which really means nothing goes).
These axioms, which are the foundation for all scientific research, are (roughly) as follows:
1. I exist.
2. An external objective reality that can be perceived by my consciousness exists.
3. My consciousness, which is predated by the fact of objective existence, allows me to subjectively perceive objective reality.
Axiom #1 implies consciousness as the requirement for a perceiver (I.E., one who perceives reality). This, in turn, automatically implies objective reality (things) as pre-existant to consciousness; perception cannot exist without something to be perceived. The two are tied together by the fact that we are each individual consciousnesses subjectively experiencing a common objective reality.
Regarding the nature of things, the law of Non-Contradiction states that a thing cannot be and not-be at the same time. Objective reality exists independent of subjective perception.
TL ; DR version:
Something is (existence).
Something is something (identity).
Something can be perceived (consciousness).

More info will be added to the OP later in regards to Objectivist epistemology and some of Dennett's views of determinism in free will.
