This post is dedicated to Drew Summitt, who has relentlessly pushed Aristotelian metaphysics upon me. It is also a technical followup to this piece.

To have beliefs, one must have a lot of other beliefs. This is John Searle’s summary of the point that, in analytic philosophy anyway, goes back at least as far as W. V. Quine. No lone belief is coherent in isolation, but only as part of a web of beliefs that provide it with context.

Rather than a web, Searle spoke of a Network. At first he believed the Network was a set of unconscious beliefs that provide context for conscious beliefs. But in time he came to see that the notion of an “unconscious belief” is dubious. Instead, we ought to speak of having the capacity to generate some specific belief.

We think of memory as a storehouse of propositions and images, as a kind of big library or filing cabinet of representations. But we should think of memory rather as a mechanism for generating current performance, including conscious thoughts and actions, based on past experience.

(…)

Instead of saying “To have a belief, one has to have a lot of other beliefs,” one should say “To have a conscious thought, one has to have the capacity to generate a lot of other conscious thoughts. And these conscious thoughts all require further capacities for their application.”

The Network is the specific set of capacities for generating the relevant beliefs. It is a subset of the Background, which are all of the non-mental capabilities that generate mental states.

I find this taxonomy compelling. I would summarize the basic insight as follows: consciousness, knowledge, beliefs, and all mental states are performed, not stored. As Richard Moodey put it, “I imagine ‘knowledge’ as inseparable from acts of knowing, as something performed, rather than possessed.”

So we have performed mental states, and we have capacities for generating them. What is the ontology of these capacities? Continue reading “Where Do Beliefs Come From?” →
