 Samuel Fleischacker (1992) proposes a more moderate version of incommensurability – sometimes we can understand others just well enough to know that we don’t understand them. His argument has roots in Wittgenstein’s view that knowledge depends on a background of shared assumptions and standards of evidence. “World pictures” are embedded within cultures. Our world picture involves not only a distinctive set of beliefs about the world but also an ordering of interests that determines how we go about trying to have reliable beliefs. This ordering differs from those dominant in other cultures. We in the West have given precedence to our interests in “egalitarian knowledge”(wanting and believing that people have roughly equal access to the truth) and in prediction and control of this-worldly objects. The world pictures of other cultures embody other interests, and we may not be able to prove that they are wrong, or indeed, we may be unable to fully understand why it is that they value the interests they value so highly. Nevertheless, we understand that they do value these interests highly and think they are wrong to do so. We make such judgments despite our merely partial understanding because we tend to see a certain set of interests as the proper guide for a minimally decent or sensible human life.
