Fear of Knowledge: Against Relativism and Constructivism by Paul Boghossian

Boghossian is a professor of philosophy at New York University. This is a short, well-argued book, although its title is misleading. Its subject is doubt about knowledge or the dismissal of knowledge. The idea that anyone is afraid of knowledge is only mentioned once on the next to last page.

Boghossian’s main target is constructivism: the idea that “knowledge is constructed by societies in ways that reflect their contingent social needs and interests”. He points out that constructivism comes in different varieties. The benign version simply notes that we gather knowledge about topics we’re interested in or need to investigate. He is concerned with versions that lead people, often academics, to say that no group’s or culture’s beliefs are more valid or accurate than anyone else’s. From the epilogue:

There look to be severe objections to each and every version of constructivism about knowledge that we have examined. A constructivism about truth is incoherent. A constructivism about justification is scarcely any better. And there seem to be decisive objections to the idea that we cannot explain belief through epistemic reasons alone.

On the positive side, we failed to find any good arguments for constructivist views…. At its best, … social constructivist thought exposes the contingency of those of our social practices which we had wrongly come to regard as naturally mandated. It does so by relying on the standard canons of good scientific reasoning. It goes astray when it aspires to become a general theory of truth or knowledge. The difficulty lies in understanding why such generalized applications of social construction have come to tempt so many.

He believes that the appeal of constructivism is mainly political, although misguided:

Constructivist views of knowledge are closely linked to such progressive movements as post-colonialism and multiculturalism because they supply the philosophical resources with which to protect oppressed cultures from charges of holding false or unjustified views. [But] if the powerful can’t criticize the oppressed, because the central epistemological categories are inexorably tied to particular perspectives, it also follows that the oppressed can’t criticize the powerful.

Apparently, Boghossian doesn’t recognize the appeal of oppressed groups being on an equal footing with the powerful (“your views are merely a matter of perspective and no more valid than ours”). He concludes:

The intuitive view is that there is a way things are that is independent of human opinion, and that we are capable of arriving at belief about how things are that is objectively reasonable, binding on anyone capable of appreciating the relevant evidence regardless of their social or cultural perspective. Difficult as these notions may be, it is a mistake to think that recent philosophy has uncovered powerful reasons for rejecting them.

Truth: A Guide by Simon Blackburn

This is an excellent discussion of the philosophical issues concerning truth.

Blackburn argues for a minimalist version of truth: assertions of any kind fit into the schema “‘P’ is true if and only if P”, even ethical and aesthetic assertions.

He then navigates between four philosophical views regarding truth: 1) eliminativsm (get rid of it!); 2) realism (get it right, and then talk of truth, ontology, reality, fact…); 3) quietism; and 4) constructivism (also fictionalism, pragmatism, instrumentalism, expressivism…). In the end, he supports realism of a modest sort: a realism that is comfortable saying science and most everyday beliefs are true, which is why they bring us success in our endeavors.  (2/15/10)
