On Vulcans And Androids

Science fiction has made popular a certain trope concerning us logicians. The common depiction is that logic is somehow cold and calculating, the activity of a merely robotic kind of intelligence. In the original Star Trek, Dr. Spock captures this stereotype with his pointy-eared precision. In The Next Generation, the role is taken over by […]

The Surprising Logic of the World

Surprising Logic of the World

A logic teacher often encounters the complaint that logic is not useful, that being so abstract it is detached from the real issues of life. The student must memorize names (in Latin, of course) for basic patterns, and the examples of these patterns all seem to involve Socrates somehow. Students are made to work through […]

I thought about this when I read Kevin Laland’s article in a recent issue of Scientific American. “[H]ard scientific data have been amassed across fields ranging from ecology to […]

Stephen Hawking’s Many Universes

Why Logic?

Stephen Hawking once pronounced that he thought his brain was little more than a computer and that, because of this, he was unafraid to die: “I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story […]

The Four Questions You Can Ask About Anything

Four Questions

The most basic thing we can ask about anything is “What is it?” Young children explicitly ask this question all the time. But even adults do it, although they may not do it explicitly, or even think about doing it at all. We ask this about words we don’t know, and things we encounter for […]
