Logical positivism
Logical positivism and scientism paved the way for neopositivism, analytical philosophy, structuralism, and naturalism. Neopositivism and analytical philosophy discarded classical rationalism and metaphysics in favor of strict empiricism and epistemological nominalism. Proponents such as Bertrand Russell emphatically rejected belief in God. In his early work, Ludwig Wittgenstein attempted to separate metaphysical and supernatural language from rational discourse. A.J. Ayer asserted the unverifiability and meaninglessness of religious statements, citing his adherence to the empirical sciences. Relatedly the applied structuralism of Lévi-Strauss sourced religious language to the human subconscious in denying its transcendental meaning. J.N. Findlay and J.J.C. Smart argued that the existence of God is not logically necessary. Naturalists and materialistic monists such as John Dewey considered the natural world to be the basis of everything, denying the existence of God or immortality.
