Aristotle | Objectivism In Depth

Within epistemology, which is the branch of philosophy that studies human knowledge, one of the most fundamental topics is the nature of perception. Philosophers from the Ancient Greeks to the present have offered various theories of what perception is and how it occurs. Because it is a topic so fundamental to human knowledge, specialized natural science can’t answer the basics about it. Science relies on perceptual observations of reality. Thus science itself relies on the idea that perception allows us to be aware of an external reality. If perception does not give us awareness of external reality, then scientific study of the external world is not possible: We would always, at best, be inspecting the contents of our own minds.

Thus, it is the job of philosophy to answer the most basic question: Does perception give us an awareness of reality, and if so, at the most basic level, how?

In this essay, I’ll explain three different theories of perception. To the question of whether perception gives us an awareness of reality, all three of them attempt to answer, “Yes.” Where they disagree is on the “how,” or the basic nature of perception. The three basic theories are naïve realism, representative realism, and Direct Transformative Process Realism (DTPR.) (“Representative realism” here is a synonym for representationalism. Note that these theories are all variants of “realism” in perception. Theories that answer “No” to the question of whether we can observe mind-independent reality would be variants of “idealism.”)

Philosophers sometimes use “naïve realism” as a synonym for “direct realism,” and there are many different theories that could be called “direct realist.” But here I will take “naïve realism” to be one specific sort of direct realist theory: the sort of approach to perception exemplified by the Ancient Greek philosopher, Aristotle. Representationalism too has quite a few variants, but they all share a common thread. I will focus largely on the version of representationalism associated with the English philosopher, John Locke. Direct Transformative Process Realism (DTPR) is my term for the theory of perception put forward by Ayn Rand and Objectivist intellectuals after her. It’s a form of direct realism that is very different from Aristotle’s approach. I’ll explain this term in more detail when I explain this theory later in this essay.

Plato points upward in Raphael's fresco, "The School of Athens." Plato was a Platonic "moral realist." He believed that a "Form of The Good" resided in extra-mental reality.

Plato in The School of Athens

What is the basis for an objective morality in under 1000 words? Where does mainstream Moral Realism go wrong? What error did Plato make that has negatively affected philosophers’ ethical assumptions even into the 21st Century? What is the meaning of modern, moral “error theory?”

If you are interested in any of these questions, I think you’ll want to see the answers given in the dialogue contained in this post.

First, a bit of context: I posted this article on the philosophy section of reddit: Answering Sam Harris’s “Moral Landscape Challenge”. The first comment below is responding to and quoting that posted article. I respond to that comment, and another poster responds to me, starting the dialogue. I am “Sword_of_Apollo” in this dialogue:

LaoTzusGymShoes:

Some of these facts may be apparent, animals certainly seem to prefer warm, comfy shelter and food to the cold, and starvation, but others seem to be fairly dramatic assertions, that would be much more convincing with argumentation.

For instance

“The basic problem with all variants of utilitarianism, including Harris’s, is that there is no reason to act for the well-being of other conscious creatures, apart from how doing so redounds on one’s own well-being.”

This is a bold assertion. I don’t see this as being obvious in the slightest. Indeed, I’d say there’s no reason to only value my own well-being, when I have every reason to believe that I’m the same sort of being as other humans*. If my well-being is important, then why shouldn’t their’s be as well?

*also, don’t animals deserve moral consideration, at least to some degree? I mean, you don’t have to be vegan or whatever, but kicking a puppy doesn’t really seem morally neutral.
