A book by this philosopher describes that people first held “naïve monism,” in which no distinction is made between natural and normative laws, as the first step in a process that ends (-5[1])with “critical dualism.” In a 1967 lecture, this philosopher claimed that the universe only had one world at its inception, but a second one emerged from biological evolution and a third from human’s “products of thoughts.” This thinker argued (10[1])that scientific theories should be risky (10[1])and prohibitive (10[1])as a part of a solution to the demarcation problem. (10[2]-5[1])That solution revolves around this thinker’s most famous concept, (10[1]-5[1])found (10[1])in the book (10[1])The Logic (-5[1])of Scientific (-5[1])Discovery, (10[4]-5[2])which is demonstrated with the finding of a black swan (10[2]-5[1])proving that every swan (10[1])is not white. (10[1]-5[1])For 10 points, (-5[1])name this Austrian-born philosopher of science who invented (10[1])the concept (10[1])of falsifiability. (10[3]0[1])■END■ (10[11]0[5])
