Our mission is to nurture a community in the Miami Valley that values secular humanism, promotes and preserves freethought in the public square, provides supportive fellowship, and engages in humanitarian good works.

Reason Rally in the rain!

Freethought Dayton came out in big numbers and  made a big splash at the Reason Rally yesterday.  It was an incredible day jam-packed with one amazing thing after another. Below is a quick news piece about the event.



Here are some highlights:

Tim Minchin somehow avoided the censors and entertained us with his wild songs and his dirty mouth.

Richard Dawkins was welcomed to the colonies with great enthusiasm. His speechwas also well received…

There was an issue with the Hitchens video tribute. I’m sure they’ll post it soon… While we wait for that, here’s another tribute video.

Some Christians were there… most of them were protesting us. I’m not really sure why.

I walked over to the circus of protestors (exit stage left). Weirdly enough I had no real interest in engaging them in debate or discussion. Like me, most of us were probably really there to celebrate and to rally. But some people had some fun (wasting time) arguing with young-earthers and spiritualists.

In the afternoon it seemed to get progressively colder. The rain continued but we hung in there… Later in the day Tim Minchin stepped in and helped warm us all up… then Eddie Izzard entertained us with his special comedic offerings.

Speaker after speaker blew us away with profound, funny or interesting words, ideas, and performances…

Here are some pictures from the event.

Where you there? Tell us about the rally and the trip.

Horse Evolution

Horse Evolution

“This is an artist’s reconstruction of Sifrhippus sandrae (right) touching noses with a modern Morgan horse (left) that stands about 5 feet high at the shoulders and weighs about 1,000 pounds. Sifrhippus was the size of a small house cat (about 8.5 pounds) at the beginning of the Eocene (approximately 55.8 million years ago) and is the earliest known horse. (Credit: Danielle Byerley, Florida Museum of Natural History)”

“This is a way too-cool cool illustration reflecting the evolution of horses from the small, three-toed, equines of 56 million years ago to the massive one-toed animals we know and love today. Unlike the diversity of human induced selection in dogs, the horse is entirely the product of selection through the utterly fish-eyed indifference of nature; a change similar in scope to the changes seen between cabbages and Brussels sprouts, though not so radical as the change between the native little tar weed of coastal California and the majestic silver swords found on the volcanic mountains of Hawaii.”
