Postmodernists seem to hold that (a) it is impossible to absolutely understand reality and (b) objective truth does not exist. It seems that these two assertions are conflated but distinct. (a) is reasonable but mundane, whereas (b) is quite extreme. It is almost as if we assert that, because it is impossible to absolutely understand reality, then it makes little sense to do so. Do postmodernists give much thought to this distinction, or is it simply a type of Motte-and-Bailey fallacy? Thank you very much.
