Induction is absurd

by Neil Rickert

The term “induction” is used in a variety of ways. For example, it is sometime applied to statistical inference. I do not find anything absurd with statistical inference, if it is done properly.

The absurdity that I am posting about, is with respect to what is sometimes called “philosophical induction.” Here’s an example of that kind of induction:

All the many crows that I have seen are black. Therefore all crows are black.

That’s the example that David Stove used in his book “The Rationality of Induction.”

We are born into a world where there are no crows. As a child grows, she eventually learns to carve that world up into parts and to name the parts. What we call “crows” comes from that carving up operation (or that categorizing operation). For that matter, we are born into a world without black. We later learn to categorize into colors such as black, green, red, blue, yellow. That we have black things depends on our categorizing into colors. That we see crows depends on our categorizing into things.

Are there laws of nature?

by Neil Rickert

This post is partly a reaction to a recent post that I saw at Erraticus.

That blog post is mostly a discussion (or disagreement) between two people, David and Margaret, about whether there are laws of nature. David thinks that there are, while Margaret is a skeptic.

As best I can tell, both David and Margaret are fictional. The author, Eleni Angelou, is using them to bring out some of the controversy involved with that topic.

I’ll start with my answer. No, there aren’t laws of nature. There are laws of physics, but those are not laws of nature. The distinction here is that I see laws of physics as human constructs, while I understand “laws of nature” to refer to things that are said to be independent of humans.

That puts me on the side of the skeptic. If anything, I am even more skeptical than Margaret.
