Attacking the Evolutionary Argument Against Naturalism

My last post presented what I feel is the strongest form of the Evolutionary Argument Against Naturalism (EAAN) promoted by Alvin Plantinga.

Today I will attempt to refute it.

Rather than argue as some have that we can rely on our reason because of tools developed over centuries by a process of cultural evolution, I want to show that even the primitive faculties provided to us by evolution have given us abilities in this regard.

Unlike Plantinga, I certainly do not accept the premise that evolution and naturalism imply a low probability that we can reliably form beliefs.

Defending The Evolutionary Argument Against Naturalism (EEAN)

As part of a disagreement with philosopher Massimo Pigliucci on Rationally Speaking, I have found myself in the unusual position of having to defend Alvin Plantinga's Evolutionary Argument Against Naturalism.

As a firm proponent of philosophical naturalism, I do not find the EAAN to be persuasive. However, I feel that Pigliucci has treated the argument unfairly, glossing over the crucial point and picking at irrelevant details.

In this post, I will attempt to defend the argument and present it as persuasively as I can. In a later post, I intend to refute it.

Strong AI: Conclusion

I've taken a long hiatus while I tried to think if there was anything substantive I had left to say about Strong AI. I didn't come up with much, so I'll wrap it up with this post.

Strong AI: The Gödel Problem

In my previous post, I alluded to an argument made by John Lucas and popularised by Roger Penrose against the possibility of AI, and this is that Gödel's Incompleteness Theorems suggest that even weak AI is impossible. We could never make a computer system that behaved intelligently.

Loosely put, Gödel's Incompleteness Theorems put fundamental limits on what can be achieved by working with formal systems.

In particular, some argue that they show that formal systems can never be as intelligent as human beings. In this post, I argue against this view and propose that humans are subject to the same limitations.

Strong AI: Naturalism and AI



In this article, I want to examine the issues presented by the problem of consciousness when examined from a naturalistic or physicalist point of view. What I present in this article is probably not a knock-down argument proving the computational theory of consciousness (Strong AI) within this framework. Rather it shows that the alternatives are rather problematic.

Strong AI: The Illusion of Real Consciousness


Perhaps we are no more conscious that the automatons we imagine in our thought experiments when considering questions about artificial intelligence and philosophy of mind.

In this view, all we have to explain is why we believe we are conscious, without explaining why we actually are. "Real consciousness" is an illusion, and consciousness is simply comprised of the functions it affords, namely the ability to be self-reflective, to deliberate, to perceive the world, etc., in such a way that the entity believes itself to have a subjective experience or "real consciousness".

If we allow the assumptions of Weak AI, namely that it should be possible in principle to create a computational artificial intelligence which has all the functionality of a human brain, then all of these abilities can be achieved. If we deny Strong AI, then we must suppose that the AI will falsely believe itself to be conscious.

If we understand how artificial intelligences might believe themselves to be conscious, then we can understand by analogy why biological intelligences might share those beliefs. In other words, if we have explained our belief that we are conscious (by analogy to our artificial intelligences), then what, exactly, remains to be explained?

Strong AI: Evolutionary Parsimony


In this post, I will attempt to make an argument for Strong AI from an evolutionary perspective. Please keep the assumptions stated in my previous post in mind.
