This week I’m going to continue the discussion of “common sense” from two weeks ago. I think it’s an important discussion because an overreliance on the concept of “common sense” can be (and seems to have been repeatedly) used to challenge the value and viability not merely of “religion” but of philosophy itself. I’m going to assume that readers of this current post have read that previous post – but not that they have read the comments on it, which have been the most numerous of any post on this blog so far (a full hundred!)

In those comments I challenged Thill to define the term “reliable,” which he had previously introduced to the discussion. I structured the post around the term “reliable” because in Thill’s previous comment, it had been at the centre of his only serious response to the point that “common sense” can be wrong (as in the case of sunrise and sunset). He said: “The fact that it is not infallible does not support the conclusion that it is not reliable!” No doubt I should have probed the definition of “reliable” further in the post – examining what Thill could have meant by it; I did not. I tried to make up for that lack in a later comment, where I asked Thill to define “reliable.” Thill responded that the onus was on me to define “reliable” since I had advanced a thesis relating to it; but my supposed thesis was intended as a response to his own thesis about the reliability of common sense, a word which, again, he introduced to the discussion. So I noted that I am happy to drop the term from the discussion as long as he, too, is willing to refrain from using the term “reliable” to refer to the epistemological status of so-called common sense. (That also applies to the others, Jabali108 and Neocarvaka, who have been exalting “common sense” in recent discussions.)

If we drop “reliable,” where are we left? Continue reading →
