Ryan Bell: "I don't think that God exists"

Ryan's "Year Without God" is almost over, and he has started talking about where he has ended up - much to the dismay of some Christians. Ryan will be also be speaking at ReasonCon 2015 in Hickory (in April). Get tickets now...

"I think before I wanted a closer relationship to God and today I just want a closer relationship with reality."
 - Ryan Bell

Ryan recently spoke to NPR about his experience.

He is also tweeting and blogging his thoughts...

The Real Reason for the Season?

Happy winter solstice! Tomorrow (Sunday) is the shortest day of the year. But what causes the seasons?

Via the Bad Astronomer
And how do we know the Earth orbits the Sun?

Just something to think about...

What is humanism?

Most people either smile or laugh at me when I say to watch Star Trek, so here's the abridged version:

Or just listen to Gene Roddenberry accept the 1991 Humanist Arts Award from AHA.

That's humanism! OK? :)

I watched as many of the Star Trek episodes in this video as I could with my children when they were young, and we talked about the issues and themes that were raised (another one of my favorite episodes that is not in this compilation is TNG's The Chase). And I think my children turned out pretty good. They also liked the Wizard of Oz and the Lion King. :)

Doubt: A Prerequisite to Finding Out

"My argument is not with people who search for God. My argument is with people who feel that our understanding of God is completed." - Ann Druyan

Some believe they know, with certainty,
God's truth about everything under the Sun. 
Most of us have doubts and uncertainties
That go far beyond whether or not He had a Son.
We learn and have new experiences,
Not because we already know everything.
But because we have humility and doubt,
And then we try to actually find out.

E.O Wilson: 'The Meaning of Human Existence'

I just finished reading The Meaning of Human Existence by the world's leading expert on ants. It's a quick read (only 208 pages) with, I think, an important philosophical message best summed up by this quote from the book:
"Exalted we are, risen to be the mind of the biosphere without a doubt, our spirits uniquely capable of awe and ever more breathtaking leaps of imagination. But we are still part of Earth's fauna and flora, bound to it by emotion, physiology, and, not least, deep history...There is no predestination, no unfathomed mystery of life. Demons and gods do not vie for our allegiance. Instead, we are self-made, independent, alone, and fragile, a biological species adapted to live in a biological world. What counts for long-term survival is intelligent self-understanding, based upon a greater independence of thought than that tolerated today even in most advanced democratic societies."
Jerry Coyne (also a biologist) isn't much interested in reading it and calls it "scientism." In Wilson's defense, he does spend a chapter on "The Meaning of Meaning" explaining his non-standard usage. And unlike in the video Jerry included in his post, Wilson doesn't really disparage philosophy in the book (religion does take a beating however). He even includes a chapter on "The All-Importance of the Humanities" (or "that which makes us human" as he describes it) and explains why he thinks the humanities (and not our science or technology) is what would interest an ET the most.

Wilson's "new enlightenment" philosophy finds no "meaning" to human existence in the sense of intention or design. But he does find "meaning" in our deep history and the contingency of life, and in the knowledge that we are part of, and dependent on, our biosphere. And he finds "purpose" in our being good stewards of our own future and of the biosphere on which we depend.

I didn't get hung up on the meaning of the word "meaning," but like both Jerry and E. O. I'm only an amateur philosopher. :)

Big Questions: How Do We Really Know Stuff?

A couple weeks ago, as my inquisitive daughter and I were driving along a North Carolina highway, we began talking about how amazing it was for humans to land a laboratory the size of a washing machine on a comet only 2.5 miles wide, orbiting the sun at a brisk 84,000 mph and 300 million miles from Earth. The discussion turned to the knowledge the engineers and scientists must collectively have known in order to pull off such a tremendous feat. How did they gain the necessary knowledge? The discussion soon drifted to the Big Bang Theory (not the sitcom) and an admission by my daughter that she didn’t enjoy thinking about cosmology because she couldn't comprehend the concept of infinity. She told me she knew the universe was expanding at the speed of light, and has been for over 14 billion years, but didn’t know what space it was expanding into! “There had to be something beyond the edge of the expanding universe,” she said. That’s when I switched to my fatherly, teaching voice and said, “It’s perfectly fine to not know the answer and simply say, I don’t know.”

All of us ponder the big questions at some point in our lives. What existed before the universe? How did we get here? Are there multiple universes? What is beyond our own expanding universe? In order to answer these and other big questions about our existence we must develop a mechanism to confidently gain accurate, objective knowledge. Generally, there are two ways that we, as individuals, go about our quest to seek knowledge that satisfies our deepest questions. The first is to adopt an already existing narrow ideology, which claims to know all the answers to the big questions. The second is to spend the bulk of our lives painstakingly learning past knowledge and demanding empirical and rationally obtained evidence of those facts before personally accepting them as likely truth or knowledge. Only then can one continue discovering new facts through rigorous, disciplined, proven methods which build upon past knowledge.

"I want to believe as many true things and as few false things as possible."
- Matt Dillahunty

Unfortunately, most people obtain at least some of their knowledge from religion. Religion moves sneakily between reality when convenient and magic when it must. It makes absolute claims based upon human fantasies of eternal life, an omnipotent, protective father figure, and a universe which is centered on the human species. It will use established science when it’s in line with their claims, condemn science as evil when it’s not, and manufacture false truths as necessary to support its teachings. It plays to human desire and fear, discourages questioning and curiosity, and demands absolute adherence of its followers. It is void of any genuine self-correcting measures. In the end, all religions rely on faith, a belief without evidence, to get buy-in to their product. It is no wonder faith as a virtue is pushed so aggressively by clergy and used as a source of pride in nearly every religion. Unproven knowledge is simple to obtain, but how do we discover what is real in our cosmos?

“Faith is the excuse people give for believing something when they don't have evidence.” - Matt Dillahunty

Science is the best mechanism we have for obtaining objective facts. It is not easy, fast, convenient, or even correct all the time, but it has allowed humans to send man to the moon, roving laboratories to Mars, develop effective vaccines, build the Boeing 777, find and exploit the invisible electromagnetic spectrum, discover ultrasound and radar, invent the device you are reading this from, and the list goes on and on! This is all possible because of the scientific method, which encourages opposing ideas, honest peer review, but most importantly demands a preponderance of evidence based upon repeatable and predictable outcomes. When a scientist makes a claim of truth or knowledge, he/she will submit it to scientists all over the world and challenge them to discredit the findings and attempt to duplicate and verify the supporting evidence. The proud scientist who finds errors in another’s claims not only moves mankind closer to actual knowledge, but also deserves a promotion!

Danger! Red Flag! ^^

Unlike religion, science never dismisses the possibility that it could be wrong or partially wrong about its claims. Albert Einstein famously modified Sir Isaac Newton’s theory of gravity by finding a more precise definition and calculation thus improving the theory. A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. If enough evidence accumulates to support a hypothesis, it moves to the next step—known as a theory—in the scientific method and becomes accepted as a valid explanation of a phenomenon. Scientific theories can become more precise or even change based upon new reliable evidence. Religious apologists often parrot their minders by declaring scientific claims such as evolution is “just a theory,” but their brand of God is absolute fact based on blind faith.

Perhaps the biggest question of all for most people at some point in their lives is whether there is a creator or god who controls the cosmos. I submit the only honest answer to that question is an emphatic “We don’t know!” No religion has so far produced testable, empirical, and predictable evidence to rigorous scientific standards that would fit into any scientific model or theory that relies on actual knowledge. If a religion produced such evidence, successfully passed the scientific review process, and contributed to science in a meaningful way, it would cease to be a faith and would be called science! Even then, it would likely only be a possibility depending on the quality and quantity of the evidence. Personally, I think it is valid to establish the concept of a creator as a remote possibility, but with no reliable evidence suggesting one thus far (the bible is as reliable for proving God’s existence as a Harry Potter novel is as evidence for wizards), it would be dishonest to take seriously and move to the scientific theory category. For anybody to claim one of man’s religions or scriptures as fact without the scientific process validating its claims is, to me, not only harmful to humans in the short term, but clearly dangerous to scientific efforts required to solve mankind's most pressing problems.
