 The vigorous attacks on Kuhn as a radical subjectivist and irrationalist who was undermining not only philosophy but the Western intellectual tradition now look exaggerated, but it is fair to say that the five big problem-complexes of normativity, incommensurability (including meaning change), relativism, social knowledge, and deep but rational progressive change are extremely difficult and remain open to debate today. For many philosophers of science, relativism is the big bugaboo that must be defeated at all costs. For them, any view that leads to even a moderate relativism is thereby reduced to absurdity. Historicist philosophers have insisted on relativity to historical context but, with few exceptions, have made a sharp distinction between relativity and outright relativism. Some critics have not found this distinction convincing (see the entry on  relativism,  Kindi &amp; Arabatzis 2012 and Richards &amp; Daston 2016).
