Interesting Blog Post about a Multiverse

"Where Are We in the Multiverse?" (@ Why There is and Why There Is Anything)Here's the first paragraph: There are two avenues from modern physics to the belief that the universe we see around us is not all there is, but is instead one of infinitely many like it. The first is inflationary cosmology; the second is quantum mechanics.  Though very different, these two multiverse models share two features: first, they both posit objective physical probabilities that tell us how likely we are to b … [Read more...]

Input Requested: Facts about Mental Properties Which Might be Relevant to Theism and Naturalism

I'm interested in collecting a list of mental properties which might be relevant to theism and naturalism. Examples:Consciousness Intentionality Reliability of Cognitive Mechanisms Mind-brain dependenceWhat else have I missed? … [Read more...]

Must Atheists Have Deductive Proofs for God’s Nonexistence to Justify Atheism?

Yet another objection to the possibility of a sound argument for the nonexistence of a god can be found in the writings of Bertrand Russell. In order to understand the basis for Russell's objection, we must first understand how Russell defined the terms 'atheist' and 'agnostic': An atheist, like a Christian, holds that we can know whether or not there is a God. The Christian holds that we can know there is a God; the atheist, that we can know there is not. The Agnostic suspends judgment, saying … [Read more...]

Inductive Logic 101 (Updated 23-Apr-14)

Here is a very quick and very rough overview of inductive logic. Almost all of it is taken from sources other than me; I'll try to identify where the material came from. The Difference between Deductive and Inductive ArgumentsLogic Type Unsuccessful Arguments Successful ArgumentsDeductive Logic Invalid* Valid*Inductive Logic Incorrect Correct*I'm oversimplifying this somewhat by ignoring the question of whether the premises are trueThe late philosopher … [Read more...]

Simplicity, Theism, and Naturalism

In a recent post on his blog, Alexander Pruss presents an interesting argument regarding simplicity, theism, and naturalism. He writes: I have argued elsewhere, as my colleague Trent Dougherty also has and earlier, that when we understand simplicity rightly, theism makes for a simpler theory than naturalism. However, suppose I am wrong, and naturalism is the simpler theory. Is that a reason to think naturalism true? I suspect not. For it is theism that explains how simplicity can be a guide to … [Read more...]

A Good F-Inductive Argument for Theism based on Consciousness

I was waiting for someone to bring this up in the combox on my recent post on Swinburne's cosmological argument, but no one did. The argument from consciousness (to theism) is a parallel argument to the cosmological argument against theism.In the cosmological argument against theism, I pointed out that naturalism entails a physical universe whereas theism does not. Since a physical universe exists, it follows that the universe is evidence favoring naturalism over theism.The parallel … [Read more...]

New Scientific Evidence for the Multiverse

I have always been a multiverse skeptic. If this article in New Scientist is accurate, however, it appears the recent confirmation of chaotic inflation also provided some evidence for a multiverse.LINK (HT: Ex-Apologist) … [Read more...]

F-Inductive Arguments: A New Type of Inductive Argument

In his extensive writings, the prestigious philosopher Richard Swinburne makes a useful distinction between two types of inductive arguments. Let B be our background information or evidence; E be the evidence to be explained; and H be an explanatory hypothesis.“C-inductive argument”: an argument in which the premisses confirm  or add to the probability of the conclusion, i.e., P(H | E & B) > P(H | B).“P-inductive argument”: an argument in which the premisses make the conclusion pro … [Read more...]
