 As for the influence of Roy Wood Sellars, the first thing to note is that Sellars as early as 1918 had published a book titled The Next Step in Religion. In the preface to that book, Sellars made it clear that “the deepest spiritual life has always concerned itself with the appreciation and maintenance of values. He who acknowledges, and wishes to further, human values cannot be said to be irreligious or unspiritual” (Sellars 1918, Foreword). Moreover, Sellars pointed out: “Such attitudes and expectations as prayer, ritual, worship, immortality, providence, are expressions of the pre-scientific view of the world. But as man partly outgrows, partly learns to reject the primitive thought of the world, this perspective and these elements will drop from religion.” (p. 6) On this basis, religion is redefined as “loyalty to the values of life” (p. 7). In fact, Sellars’ approach is deeply rooted in an appreciation of the progress of science (see esp. Sellars 1918, ch. XVI) and thus comes quite close to Feigl’s understanding of what he called scientific humanism. Moreover, Feigl had certainly read the Humanist Manifesto, which Sellars, together with Raymond B. Bragg, had co-edited in 1933 (see Kurtz 1973). As late as 1980, Feigl (like Willard von Orman Quine, A. J. Ayer, and Sidney Hook) signed the Secular Humanist Declaration of the Council for Democratic and Secular Humanism (see Kurtz 1983).
