1) That reality is independent of experience.
2) That all knowledge about reality is derived from experience.
It follows from claim (1) that if reality is in fact independent of experience, it would be impossible to derive any knowledge about reality based on that experience.
On the other hand, it follows from claim (2) that if all knowledge about reality is derived from experience, it would be impossible to claim that reality is independent of that experience.
Therefore, the above two claims are inconsistent. If Objectivism is to maintain its insistence as an integrated philosophy, one or other of these claims must be discarded.
Objectivism makes no claim that "reality" is independent of experience, in the sense that it cannot be experienced or that it does not include experience. The objectivist view is that reality is what it is, whether it is experience or not, and our experience of it in no way changes its nature. Reality is the object of objectivism.
But I've noticed in all of this discussion a confusion of terms that really needs to be explicated. It is a confusion objectivists themselves are guilty of, including Rand, Peikoff, and Kelly. If more people would introduce themselves to classical logic, many of these confusions would go away. One of the confusions is meaning and connotation of words.
This is what the objectivists should have made explicit:
Existence - All that is. Includes, rocks, trees, the solar system, the physical universe, justice, nostalgia, objectivism, Santa Claus, and the Tooth Fairy.
Reality - All that is the way it is Reality and existence have the same "content" (extension, particulars) as existence, but reality differentiates that content based on what the ancient logicians called, "mode of existence." Rocks, trees, the solar system and the universe exist physically (sometimes called material existence), justice, nostalgia, and objectivism exist as ideas, but not as physical existents, Santa Claus and the Tooth Fairy exist but only as fictions.
Material existence is all that exists whether anyone is aware of its existence or knows anything about it. Its nature and all that exists materially exists independently of our knowledge or awareness of it.
Physical existence is all we are directly conscious of (that is, perceive). The objectivists fail to distinguish between material and physical existence which is minor, but still a mistake. Life, consciousness, and volition all exist independently of any particular persons awareness of them, but are not physical in the sense that we can be directly aware of them. They are material, because the exist "objectively" but we cannot directly perceive life, or consciousness, or volition.
Objectivists usually mean by existence, "physical" existence, but sometimes "material" existence, and sometimes, "reality." The failure to make these concepts explicit (they need not use the same words) has caused them much trouble.
The important point is, material existence is what is independent of our knowledge of it, and the truth or veracity of our knowledge of it is determined by its nature, not anything we think or believe about it. In this sense, material existence is absolute, as opposed to contingent. Everything else that exists is contingent, because it depends on human volition for its existence. All knowledge, all science, all works of art, all fiction are contingent in the sense they depend on human action (mental or physical) for their existence and their nature.
Can we begin here?
