David Gelernter. The Muse in the Machine. (1994) A strange book, which makes a number of major points or claims.
First, Gelernter posits a spectrum of attention, from the barely conscious, half-recalled dream state to the rational, hyper-focussed attention and linear thinking that we’ve learned to accept as the best kind. However, says Gelernter, creativity is highest when attention is low and the mind “wanders.” Hyper-focussed attention is on the contrary not very creative. Its main (and perhaps only) value is to bring order to the usually chaotic structures of the insights created when our attention is low.
There’s some truth to this. In fact, it’s become a pop-psych cliche. Every now and then some analogy tripped over when the mind wanders triggers an insight. But in my experience those events are not guaranteed. In fact, they are rare enough to make them memorable. I think that pretty well everybody has worried a problem until a solution “presented itself” unexpectedly. But we know that it’s a process that we can’t control. About all we can infer is there is a lot of thinking well below the level of conscious attention, some of it surfaces, and occasionally the product is useful. We can allow this process to work by letting go of a problem and chilling. But there’s no guarantees.
Second, the mind is not software. I agree, in part for the reason Gelernter puts forward, which is that the analogy of “mind” with “virtual machine” breaks down. A virtual machine is one that’s implemented in software running on another machine. Abstract the concept of “machine” to an entity that performs some task in response to some input, then any program is a virtual machine. E.g., the wordprocessor I’m using takes data from the keyboard, and transforms that into a block of data in memory. It sends copies of the data to the graphics processor, which translates them into a display on the monitor. When I hit Print, it sends data to the printer, which in turn lays microscopic dots of ink onto a sheet of paper. To my eye, it’s the text I composed.
The analogy is that “mind” is a massive data-processing program running on the brain. Or a mess of such programs running in parallel. Hence a virtual machine. Write the program(s) in a suitable language, and the “mind” can run on any capable “substrate.” Such is the fantasy supporting the desire to “upload” the self and live forever. Gelernter is no biologist, but he argues that his concept of an attention spectrum requires a body. IOW, a mind cannot exist apart from a body. I agree, but my reason is I think somewhat simpler. The brain’s primary function is to operate the body. Most of its energy is expended in doing just that.

“Thinking”, such as it is, takes up a very small part of the brain’s energy budget. Being “me” is what thinking is mostly about, and it’s really just an afterthought.
The last part of the book is a nicely done symbolic reading of the Song of Solomon. Gelernter is a believing Orthodox Jew. He posits that the hyper-focussed attention that we nowadays equate with thinking is a recent development. (Schooling is intended to train us to think this way.) An unfortunate effect of high-attention rational thought is a misreading of ancient texts, which are, he says, the products or records of low-attention thinking, hence their nonlinear narratives, symbolism and metaphor, and reliance on analogy to make both narrative and thematic sense. I think this is the most valuable part of the book. But it doesn’t prove that the concept of an attention spectrum explains creativity.
A curious book, with many interesting and useful insights. Worth a read. **½
