so who's irrational?

A common accusation of atheists is that christians are irrational, preferring faith to evidence. To some christians this is not an insult, for they choose faith over logic. But other christians find this accusation both insulting and untrue, for they believe faith is based on reason and evidence.

I cannot recall anyone providing any scientific evidence for this claim. The evidence generally offered is simply that christianity involves faith, faith is not based on evidence and that is irrational.

I have just come across a book which turns this argument on its head. The Making of an Atheist by James Speigel (a professor of philosophy) argues that many atheists come to their beliefs by non-rational means. I have not read the book, but I have read parts of it and several reviews.

The book is based on scriptural teaching, but it uses evidence from psychology, the philosophy of science and atheists' own words, to establish this conclusion. The author argues that experiences in childhood, unwillingness to submit to God and immorality are all psychological factors leading to disbelief.

I'm sure there is truth in all this, although I feel some atheists I have "met" on the internet also have other, more honourable, reasons for their lack of belief in God. And I don't think I'll be using this book's conclusions to press any atheists to believe - I have objected often to atheists making unbased psychological explanations for my belief, so I don't think I should return the "compliment".

But it may be helpful to know what is in this book. At least it provides a counter to the old "christians are delusional" argument should I ever be really pressed on the matter.

is that true?

Came across this today on this blog - a list of statements that people sometimes make, but which are actually "self-refuting" or logically inconsistent. I think they're worth sharing.

  • Truth does not exist (Is that a true statement?)
  • Nothing is absolute (Is that absolutely true?)
  • I do not exist (You must exist to deny that you exist)
  • Science is the only way to know (Can you scientifically prove that?)
  • Only what can be perceived by the five senses exists (Can you prove that by the five senses?)
  • Nobody can know anything for sure (Do you know that for sure?)
  • Nobody can know anything about God (How do you know that?)
  • Talk about God is meaningless (Since it is a statement about God, this statement is meaningless too)
  • Reality is just your interpretation, objective reality does not exist (That’s just your interpretation)
  • “‘Everything we think and do is the function of our genes/nervous system’” (Is this belief itself just the result of genetic/neutral activity? If so, why trust it — or any belief we have? If your belief happens to be right, it’s just by accident)
  • There are no beliefs (You expect me to believe that?)
  • Everything is meaningless (So is that statement)
