I want to make two points in this post about know-how and intellectual ability: one critical, one defensive.
In The Concept of Mind, Ryle argues that a certain "intellectualist" view of the mind is mistaken. According to this intellectualist view, all intelligent action consists in a two-step process of theorising about a course of action and then making use of that theorising in order to go guide one's action. Ryle is not particularly clear on either of the two crucial notions invoked in this claim, namely, "intelligent action" and "theorising". For my purposes, it is adquate to suppose that theorising consists of any sort of propositional deliberation and, in particular, propositional deliberation about ways of acting. The other notion is more difficult to pin down. The following is, I believe, a fair characterization of the class: an action is an intelligent action iff it is the sort of action which can be appropriately characterized by terms of intellectual evaluation (as I will call them). The terms of intellectual evaluation are then given be (partial) enumeration: "witty", "clever", "stupid", "brilliant", etc.
Against this background, Ryle argues that intellectualism leads to a vicious, infinite regress. The argument goes roughly as follows.
- According to intellectualism, every intelligent act of psi-ing involvess deliberation about a way of psi-ing together with the implementation of that way.
- Implementing a way of psi-ing is an intelligent action.
- But then in order to impeliment a way of psi-ing one must engage in (n+1)-order deliberation about a way of implementing one's n-order deliberation about a way of psi-ing together with an implemenatation of that way.
- But then, in order to psi intelligently, one must first run through an infinite number of theoretical deliberations.
- This is not possible.
- Therefore, the intellectualist theory of intelligent action is wrong
In place of the intellectualist theory, Ryle proposes the following: x is able to psi intelligently iff x knows how to psi.
Now, it is relatively easy to see that there are a large number of cognitive abilities which do not give rise to intelligent actions and which are not appropopriately described in terms of know-how. For instance, I am able to see red, but seeing red is not an intelligent action, nor do I know how to see red. For instance, it is not appropriate (generally) to say things like, "Gee Marc, that was a clever seeing of red" or "Wow, you really know how to see red!" Here then is the critical point: the fact that seeing red is not an intelligent action is a bit of an embarassment for Ryle; so is the fact that I don't know how to see red. The problem that such cases give rise to is that cognitive abilities fall into two classes, those that give rise to intelligent actions and those that don't. And the challenge for the Rylean is to say what distinguishes the two (and why) in such a way that does not entail intellectualism. From what I can see of the terrain, this doesn't look like an easy task. For instance, I doubt that it can be done simply in terms of learning. For instance, there is nothing concpetually incoherent about saying that somebody know how to psi innately (or at birth).
But these observations also provide the basis for an intellectualist response to Ryle's regress. For once it becomes clear that there are cognitive abilities associated with our intellectual lives which do not give rise to intelligent actions (or know-how), it becomes clear that there is very little intuitive support for premise (2)--the claim that implementing a way of psi-ing is always an intelligent action. But if implementation is not always an intelligent action, then Ryle's regress fails.
