Intuitions, Common Sense, and “Earning the Right” to Judgments about Philosophy


“Intuitions and common sense are not, I claim, a good basis on which to reach philosophical conclusions.”

Those are the words of Michael Della Rocca (Yale) in a recent interview at 3:16AM.

Ellsworth Kelly, “Green White”

Professor Della Rocca has done a lot of work on the Principle of Sufficient Reason (PSR), “the principle according to which there are no brute facts that obtain or no things that exist without an explanation. That is, each thing or each fact has an explanation,” and much of the interview concerns what he takes to be its implications, particularly a kind of Parmenidean monism. He says:

This PSR-driven rejection of distinctions and of relations threatens some of what I call the struts of analytical philosophy: the method of intuition, realism, and discreteness. “The method of intuition” is my catch-all term for the method whereby analytical philosophers (especially) consult a magical faculty of intuition or invoke common sense, however that much abused term is understood. (It’s important to note that the appeal to common sense and the appeal to intuition are not the same). Realism is a view according to which the world is in general not dependent on our ways of thinking about it. This is roughly what Ted Sider calls “knee-jerk realism.” Discreteness is the view that reality consists of loose and separate items. And the PSR-driven monism or Parmenideanism with regard to meaning also brings down the distinction between philosophy and the study of its history. The principled rejection of this distinction is one of the most important upshots of my work in this Parmenidean, rationalist vein.

Interviewer Richard Marshall asks, “So can you summarise where we are—or should be—with regard to the use of intuition in philosophy? Are most of the leading contemporary philosophers making an error by using it?” Della Rocca replies:

Intuitions and common sense are not, I claim, a good basis on which to reach philosophical conclusions. What then should we do? My suggestion is to be alive to skepticism, to turn to the history of philosophy, especially philosophy before what I call the iron curtain of intuitions descended on philosophy, and to be guided by the PSR.

Earlier in the interview, Marshall notes some philosophers’ dimissiveness about metaphysical questions, and asks, “can you sketch for us how you defend the ‘why’ questions—why aren’t they irrelevant, nonsensical and their illumination is merely illusory as some people think?” Della Rocca says:

some philosophers don’t regard metaphysical questions as useful. It may seem surprising for some people to hear me saying this, but in a significant sense I completely agree with that statement. I regard many metaphysical questions—questions which often have robust metaphysical presuppositions—as on the wrong track, as less than illuminating, or even as distorting. But I think that before reaching that negative assessment, we must earn the right to make it. 

How is that right earned? One must

play the metaphysical game and… show in detail where metaphysical questions go astray and how the methods that are often deployed to answer them are, in effect, bankrupt… [M]uch of my work can be seen as tending to a rationalist metaphysical critique of not only metaphysics itself, but also of much of philosophy that is conducted according to methods prevalent in so-called analytical philosophy. So, although I am worried about metaphysics itself, I think that there’s a lot of metaphysical work to be done, insights to be gained, before this critique of metaphysics itself reaches its dénouement.

The whole interview, interesting throughout, is here.

Discussion welcome.
