 Feigl’s writings on practical issues like ethics, humanism, and religion are rather less well known (but see, rather recently, the reconstruction in Siegetsleitner 2014, ch. 11). Still, they are worth considering, especially since they contain some interesting applications and extensions of the logical empiricist agenda. The all-embracing idea, though, came from the eighteenth century: According to Feigl, “a new age of enlightenment, scientific as well as ethical, is our most imperative need” (1981, p. 406). Therefore, “[t]he straightforward spirit of eighteenth-century Enlightenment (e.g. Hume, Kant) needs reviving and ‘updating’” (1981, p. 399). The programmatic frame for this ‘updating’ Feigl labeled “scientific humanism” (ibid., pp. 368, 405, 408, 418)—by which he understood the attempt at a “synthesis of the scientific attitude with an active interest in the whole scale of human values” (ibid., p. 368). It was this conception within which he theorized about the relationships between ethics and logic and between religion and empirical science.
