Psychology as Pre-Science

The first time I read Gaston Bachelard’s The Making of the Scientific Mind, I didn’t really understand what I was reading. Same the second time. I mean, I understood the words, but I didn’t get the message. I was expecting to read a story about the change between pre-scientific to scientific ways of thinking. Since Bachelard’s subject is chemistry and life sciences, that transition isn’t as stark as it is in physics.

The book is full of extensive quotes from authors, now unknown as scientists, but famous at the time for writing about phenomena in the real world. Bachelard’s point is that they do so in a shallow way, often using analogies with familiar objects and their properties - the number of things claimed to be analogous to sponges is quite remarkable. These old-style “explanations” read fluently, and no doubt at the time, plausibly. Now, of course, it reads as grammatical gibberish.

It feels like reading a lot of contemporary psychology.

Those seventeenth-century authors made experiments as well. Hundreds of them, but all of them by today’s standards slightly mad, or trivial, having nothing to do with the fundamentals of the relevant science. We’re talking about experiments to prove which combination of coloured tights generates more static electricity. As if that might be significant in itself, rather than, as we would see it, a consequence of more fundamental laws of chemistry and the properties of the dyes and materials.

That feels a lot like contemporary psychology.

People have been making remarks about human behaviour and emotions since before Plato thought that laughter was a way of showing oneself superior to the person one was laughing at. Hume’s famous book is called A Treatise on Human Nature - it’s an extended rant about how devious and rotten people are, interspersed with some more conventional philosophising about the various aspects of the psyche (Reason, Passions, Understanding, and so on). Some of what Hume and others said was perspicacious, some more relevant to their times than ours, and some of it just wrong.

Psychology has many birthdates, and the publication of William James’ two-volume book on Psychology is as good as any other. It’s an odd book, with chapters on how the sense organs work, and a much more famous one exhorting us to the formation of habits as a way to simplify our lives. Descriptive anatomy right alongside old-school moralising. Psychologists have never gave up the combination. Even the ones who look as though they are doing “real science” by investigating the way the brain works, cannot resist the temptation to write pop-science pot-boilers about how their work proves we have no free will or that consciousness is an illusion.

In the next few posts, I’m going to wander around this subject.
