Why the creationist argument that “irreducible complexity” disproves evolution is utter nonsense

Irreducible complexity refers to a system (e.g., a living organism) in which the various parts work together to produce a given function, such that the function will not occur if any of the parts is removed.  Creationists claim irreducible complexity disproves evolution. Evolution refers to the natural adaptation of a species…

Darwin, the roots of words, etc

I have had the opportunity to exchange email and links with a man named Josh, who I invited to visit this blog.   Josh’s initial comment was: “Thanks for the Invite! But I must say… you and I are in for many future debates!” I could also tell that Josh and I were different by looking at the homepage of his blog, where he writes: “I enjoy apologetics, studying the Bible, and reading various amounts of other important literature. My passion in life is to please Christ.”

Recently, Josh referred me to an article he wrote last year, an article entitled “The Scientific Truth” published on his blog: http://defendtruth.blogspot.com/.   Below is my reaction to his article. 

Josh:

Thank you for bringing my attention to your article:  I’m truly glad we can have this conversation.  We certainly come from different perspectives.  Different perspectives, but not necessarily different backgrounds.  When I was young, I was told to fear God and to read the Bible. I was told that my questions were “just a phase” and that I would learn to simply love God and stop asking impertinent questions.  I was sent to Christian (Catholic) schools for 15 of my years of education.

I don’t pretend to know all the answers.  I am now an agnostic regarding many things.  I believe that the evidence only goes so far and we need to be brave enough to repeatedly say “I don’t know.”  I struggle to find explanations that make the most sense …

Why drilling for oil in ANWR will increase, not reduce, America’s oil dependence

As the world consumes oil, the world's oil is depleted.  As the world's oil is depleted, the countries that completely run out of oil first will become totally dependent upon the countries that still have oil.  Thus, the goal of any country that wishes to avoid becoming totally dependent is…

Pump up your tires to save Alaska

"HOW ALASKA CAN HELP MEET AMERICA'S ENERGY NEEDS" is an article to which Republican Senator Jim Talent of Missouri refers his constituents.  That article argues that we need to start drilling for oil in the Arctic National Wildlife Refuge (ANWR) of Alaska, because it holds 10 billion barrels of economically…

Star Trek’s Error: Spock’s lack of emotion would have made him irrational

Rene Descartes held that the human mind was separate from bodily processes.  Dr. Antonio R. Damasio disagreed, as set forth in Descartes’ Error: Emotion, Reason and the Human Brain (1994). In this book, Damasio introduced the cases of Phineas Gage (long dead) and “Elliot” (a living patient), who both suffered brain damage to the ventromedial prefrontal area of their brains. 

Gage’s brain damage occurred when a metal tamping rod was accidentally shot through his brain during a blasting operation (he recovered and lived many years).  Elliot’s damage occurred as a result of a brain tumor. They were both left with high level intellectual functioning but little ability to experience emotion. 

[Gage] seemed to be like a child, with no stable sense of what was important and what was not. He was fitful, intemperate, obscene. It was as if he didn’t care about one thing more than another. He seemed bizarrely detached from the reality of his conduct. So he could not make good choices, and he could not sustain good relationships . .

Elliot had been a good role model, husband and father before his tumor.  After the tumor, he was

weirdly cool, detached, and ironic, indifferent even to intrusive discussion of personal matters- as if such remarks were not really about him. He had not previously been this way; he had been an affectionate husband and father. He retained lots of cognitive functions: he could perform calculations, had a fine memory for dates and names, and the ability to
