This incoherence charge is by far the most difficult problem facing the relativist. It is worth noting that attempts to overcome the problem by appealing to the notion of relative truth appear not to succeed. Many versions of relativism rely on such a notion, but it is very difficult to make sense of it. An assertion that a proposition is “true for me” (or “true for members of my culture”) is more readily understood as a claim concerning what I (or members of my culture, scheme, etc.) believe than it is as a claim ascribing to that proposition some special sort of truth. Constructing a conception of relative truth such that “p is relatively true” (or “p is true for S”, or “p is true for members of culture C”) amounts to something stronger than “S believes that p” (or “members of culture C believe that p”), but weaker than “p is true (simpliciter)”, has proved to be quite difficult, and is arguably beyond the conceptual resources available to the relativist.
