William Lane Craig’s Logic Lesson – Part 4

In the March Reasonable Faith Newsletter William Craig asserted this FALSE principle about valid deductive arguments that have premises that are probable:... in a deductive argument the probability of the premises establishes only a minimum probability of the conclusion: even if the premises are only 51% probable, that doesn’t imply that the conclusion is only 51% probable. It implies that the conclusion is at least 51% probable.There are a variety of natural tendencies that people have t … [Read more...]

William Lane Craig’s Logic Lesson – Part 3

I had planned to discuss counterexamples (to Craig's principle) that were based on dependencies existing between the premises in some valid deductive arguments.  But I am putting that off for a later post, in order to present a brief analysis of some key concepts.It seems to me that an important part of understanding the relationship between valid deductive arguments and probability is keeping in mind the distincition between necessary conditions and sufficient conditions. So, I'm going to d … [Read more...]

William Lane Craig’s Logic Lesson – Part 2

I admit it.  I enjoyed pointing out that William Lane Craig had made a major blunder in his recent discussion of the logic of deductive arguments (with premises that are probable rather than certain).However, there are a variety of natural tendencies that people have to reason poorly and illogically when it comes to reasoning about evidence and probability.  The fact that a sharp philosopher who is very experienced in presenting and analyzing arguments could make such a goof just goes to sh … [Read more...]

William Lane Craig’s Logic Lesson

The March Newsletter from Reasonable Faith just came out, and it includes a brief lesson in logic from William Lane Craig. However, the lesson presents a point that is clearly and obviously WRONG, and it promotes bad reasoning that could be used to rationalize UNREASONABLE beliefs.  It appears that WLC is himself in need of some basic lessons in logic.William Craig recently debated a professor of philosophy named Kevin Scharp at Ohio State University, and in the current Reasonable Faith … [Read more...]

Does God Exist? Part 1

The overarching question for my ten-year plan is:Is Christianity true or false?After I clarify this overarching question, the first major question to investigate is this:Does God exist?I will, of course, at some point need to address the traditional arguments for the existence of God (ontological, cosmological, teleological, and moral arguments).  But I want my investigation to be systematic, and to avoid the problem of BIAS in the selection of arguments and evidence to be c … [Read more...]

Response to William Lane Craig – Part 8

I have one final objection to raise against Luke Johnson’s use of the “method of convergence".  I have been using the phrase "the devil is in the details" to summarize a number of problems with, or objections to, Johnson's use of the "method of convergence" to establish some key claims about Jesus.  But there are some specific DETAILS about the alleged crucifixion of Jesus that I have not yet mentioned but that represent more such details that raise doubt about the claim that "Jesus died on the c … [Read more...]

The Slaughter of the Canaanites – Part 1

Jehovah, the god of the Old Testament, is cruel, unjust, and evil.  Jehovah, therefore, is NOT God, because God is, by definition, a perfectly morally good person.  Since Jesus promoted worship of Jehovah, obedience to Jehovah, and prayer to Jehovah, we can reasonably conclude that Jesus promoted worship of a false god and thus Jesus was a false prophet.  But if Jesus was a false prophet, then it is very unlikely that God, if God exists, would raise Jesus from the dead.  God would not be inv … [Read more...]

Jesus: True Prophet or False Prophet? – Response to Eugene – Part 2

I have put forward part of a case against the belief that "God raised Jesus from the dead".  This case is based on the controversial claim that "Jesus was a false prophet".  Eugene has raised an objection to my case, and that objection comes in the form of an argument, an argument with a bit of logical complexity, which I have attempted to analyze and clarify.I have left some of the statements or premises of Eugene's argument as they were originally stated, but most of the statements I have r … [Read more...]
