Anti-relativist philosophers of science are often willing to concede all three points above, but insist that they do not, singly or jointly, justify the claim that scientific knowledge, in any philosophically interesting sense, is relative to its context of production. The success of science, both theoretical and applied, indicates that progress does take place. Fallibilism, the view that all scientific claims are provisional and liable to fail, they argue, is sufficient for dealing with difficulties arising from considerations of underdetermination and theory-ladenness of observations. Relativism, with its attendant denial that there could be objective and universal scientific truths or knowledge exacts too high a price for dealing with these allegedly troublesome features of the methodology and history of science.
