Different forms of methodological and ontological naturalism constitute the current near-orthodoxy in analytic philosophy. Many prominent figures have called naturalism a image, a Weltanschauung, or even a “philosophical ideology”. This suggests that naturalism is indeed something over-and-above an ordinary philosophical thesis. However, these thinkers fail to tease out the host of implications this idea – naturalism being a worldview – presents. This paper draws on remarks of Dilthey and Jaspers on the concept of worldviews in order to demonstrate that naturalism as a worldview is a presuppositional background assumption which is left untouched by arguments against naturalism as a thesis. The concluding plea is to re-organize the existing debate on naturalism in a way that treats naturalism not as a first-order philosophical claim, but rather shifts its focus on naturalism’s status as a worldview.

This paper deals with Wittgenstein’s rule-following paradox, focussing on the infinite rule-regress as featured in Kripke’s Wittgenstein on Rules and Private Language. I argue that one of the most salient and popular proposed solutions (championed by John McDowell), which argues that rule-following is grounded in “custom,” “practice” or “form of life, remains unsatisfactory because part of this proposal is the rejection of further “theory” (commonly attributed to Wittgenstein) which seemingly makes it impossible to substantiate the claim of how customs, practices or forms of life ground rule-following. I argue that this conundrum can be solved by introducing Wilhelm Dilthey’s overlooked notion of objective spirit as the objectivated sediment of historical human communality. This proposal allows us to substantiate Wittgenstein’s hints at the connection between rule-following and customs, practices, and forms of life without introducing “problematic theories.” Combining Wittgenstein’s views with Dilthey’s notion of objective spirit results in a solution that is neither skeptical nor straight, but therapeutic.
