Philosophy and Common Sense

Extract

This paper raises once more the question of the relationship between philosophy on the one hand and common sense on the other. More particularly, it is concerned with the role which common sense can play in passing judgment on the rational acceptability (or otherwise) of large-scale hypotheses in natural philosophy and the cosmological part of metaphysics. There are, as I see it, three stages through which the relationship has passed in the course of the twentieth century. There is the era of G. E. Moore, the Quine–Feyerabend period, and now a new and modest vindication of common sense is emerging in the work of Jerry Fodor.

8 This particular illusion merits more extended treatment. I learn from Denise Russell that the illusion is not universal but (to some degree at least) culture specific to communities where precise machined edges and straight lines are common. If this is sustained, perhaps Fodor's nativism will need to be modified. On the other hand, David Armstrong reports David Sanford's work at Duke illustrating the strength of the illusion among Westerners, who not only cannot shake off the mistake about length, but compound it when asked to estimate the real difference between unequal lines which have arrowheads to exaggerate the apparent inequality.
