December 23 – HumanLight

Posted on December 23, 2015


I love Carl Sagan's books, including The Demon-Haunted World, and I especially love his subtitle for that book: Science as a Candle in the Dark.

Of course, “the dark” is a metaphor for ignorance and, quite likely, fear and superstition. Science is a great way of lighting up the dark – of learning what is true, of dismantling superstition, and even of diminishing fear.

Another way of expressing that idea is “Reason as a Candle in the Dark.”

It is human reason that is celebrated by HumanLight. Other values celebrated during today's holiday include hope and compassion, tolerance and cooperation. In other words, today people are celebrating the best aspects of humanity – including those aspects we refer to when we call someone “humane.”

What do people do to celebrate HumanLight? Of course, gathering together with family or friends tops the list – and as you can imagine, most people enjoy eating together at these gatherings. Some people also bring in other festive touches such as music, dancing, candle-lightings, decorations, live entertainment, videos, talks or readings or other presentations, crafts and games for the kids. The three colors of HumanLight are red, blue, and gold.

October 12 – Free Thought Day

Posted on October 12, 2013

There was a terrible, horrible, unimaginable thing going on in Salem, Massachusetts, back in 1692. People had been accused of witchcraft, and there had been trials, and more accusations, and executions, and more accusations.

In all, about 25 people died horrible deaths because of the Salem Witch Trials—and more than 150 additional people were arrested and imprisoned—and why?


As you know, it turned out that nobody was a witch. Everybody arrested, imprisoned, and tried—and everybody killed—was innocent.

It turned out to be a case of conspiracy and lying and/or mass hysteria. People had been hateful, worried, upset, fearful—and wrong, wrong, wrong. It was a case of religion taken to a very horrible extreme—and extremism is pretty much never a good thing.


More than anything, it was a case of not using the best ideas that we humans had, even at the time. People were not using logic and reason, and they were not using due process rules of fairness, notice, and an open hearing.

On this date in 1692, the governor of Massachusetts, William Phips, wrote to the Privy Council of the British king and queen, and he outlined the ways in which the trials had gone so terribly astray. He wrote that the court was relying on non-evidence. Like an accuser saying that she saw a devil and other phantasms hanging out with the accused.

Phips's letter basically ended the trials, and someone decided to honor the triumph of reason over unreason every year on this date.

Freethought is a philosophy that says that opinions should be formed on the basis of logic, reason, and empirical evidence (you know, things we can observe, measure, test, and replicate). When all your friends are saying that the world will end on a certain date, or that stepping on a crack means bad luck, or that Facebook is removing all privacy settings—well, when you hear stuff like that, you should think twice before believing it, and check the facts before passing it on to others, and think three or four times AND check the facts before acting on it!

Don't be the victim of urban legends! Check them out at Snopes. 

Don't be superstitious! Check out what Mythbusters found when the superstition was tested. 

Looks like logic.
But it's not.
Don't be gullible! How likely is it, really, that a Nigerian prince needs YOU to send him money, and that he wants to give you tons and tons of money? If it sounds too good to be true...it probably is!

Don't be trapped by common logical fallacies. Check out this handy logical fallacy website!  You can roll over the various icons to see what logical fallacy each represents; then click the icon to see some great examples.

May 3, 2012 - National Day of Reason

This is sometimes called the Information Age, and it is true that we are almost constantly surrounded by an ocean of information. With the internet as close to hand as a telephone, up-to-the-minute information on the weather, world news, our friend's thoughts and activities, and even our own location (help! I'm lost!) is easy to access.

People of the past would be bewildered about how easy it is to sit comfortably in one's p.j.s and find out, say, how to make a basket out of pine needles or what the most popular names are from year to year. (Wait, in 2010, more girl babies were named Isabella than any other name? I don't know ANY Isabellas!) 

Anyway, what I'm getting at is that we all have a LOT of information at our fingertips. Literally.
But what good does this information do? We know that there is also a lot of MISinformation on the internet; how do we know what to believe? How can we best use information in our decision making or goal setting?

We have to use reason—critical thinking skills like synthesizing and analyzing—in order to use information well.

And today is the day to celebrate reason!

Here are some activities to practice critical thinking skills:

  • Brain Metrix has a variety of brain-training games.
  • Cyberchase does, too! 
  • Critical Thinking Web has lessons and exercises, puzzles and even philosophical questions to think about. 
  • Learn4Good has some shooting games that help develop problem solving!
  • TeachNet features some folding-paper problems to figure out.
