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 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 and prohibitive as a part of a solution to the demarcation problem. (10[1])That solution revolves around this thinker’s most famous concept, (10[1])found in the book (10[1])The Logic of Scientific Discovery, (10[1])which is demonstrated with the finding of a black swan proving that every swan is not white. For 10 points, (-5[1])name this Austrian-born philosopher of science who invented the concept of falsifiability. (10[1])■END■ (10[1])
