Three philosophies: Knowledge, wisdom and… money?

money-or-somethingI’ve talked before about Nicholas Maxwell’s criticism of current practice and philosophy of science. I’ve written about it in Finnish here and here; here is the website of the group dedicated to this idea.

To put it shortly, Maxwell’s idea is this: Science commonly takes the idea of objectivity too far and in the wrong direction. Its underlying philosophy is what he calls the philosophy of knowledge. This emphasizes that only empirically testable claims have a place in science, as opposed to metaphysics or values.

This may sound like a good idea, and it would be, given the right interpretation. But it’s being given the wrong interpretation. Values or ideologies must not affect the results obtained from science, but they should guide what resources are spent on. When you are not allowed to consider values even at this point, you often end up spending resources on something useless or harmful. So developing countries may have much more need for new technologies or researched solutions, but there’s more money in solving first-world problems. Similarly, metaphysics must not be more important than empirical results, but every theory has background metaphysics anyway, so acknowledging those would allow scientists to understand better what they’re doing.

Review: How to Think Straight about Psychology by Keith Stanovich

How to Think Straight about Psychology is an introductory textbook for psychology students — but it’s also a great introduction to what I might call practical philosophy of science.

A lot of philosophy of science, when it’s under that label, is about things like “Can science be true if it’s socially constructed?” or “How can we prove induction works when we can’t use induction to do it?” I’ve heard it’s largely uninteresting to actual scientists. But there’s something else, too, something I’ve mainly come across in The Skeptic’s Dictionary — and psychology courses at our university, where this book (tenth international edition) is currently required reading. It’s about how science really works, the things you need to understand as a scientist. It’s also about why you need science instead of something else.

How to Think Straight about Psychology is an excellent introduction to these questions, as well as dispelling misconceptions about psychology specifically. It tells, among other things, how the public misunderstands psychology because they think of Freud and science because they think of Einstein. It goes through the basic methods of science in general and how these apply in psychology, and it keeps things colourful by using examples such as the Amazing Randi, Clever Hans the Wonder Horse who was thought to be mathematically able but was actually more of a mind reader, and of course that one guy who proved that a disease was not spread by feces by eating them. Still, these are just flavour, not arguments; everything here is scientifically based, and this is one of the rare places where it’s also made very clear why this matters. Pseudoscience is also discussed and it is shown just why it is so “pseudo-“. And why it is not harmless, either.

While much of the book is a kind of apology for psychology, there is towards the end a small but candid section about when — quite often — psychology itself is unscientific.

I recommend this book for anyone, even if not interested in psychology specifically, wanting to know the “secret” behind the success of science. It illustrates well the point I wrote recently about, that science is largely based on being really suspicious about every putative belief. If only more people understood these things, there would be a lot less nonsense around.

I’m also writing another post as it were in response to something said in this book, about essentialism in science and philosophy.
