What is the main conflict in The Logic of Scientific Discovery by Karl Popper?

Popper directly and repeatedly rejects induction as a viable scientific method. The inductive method is one through which universal statements can be inferred from singular statements. In disputing the logic of deriving theory from induction, he shows how inductive reasoning leads to infinite regression or to tautologies. Popper finds inductive logic internally inconsistent. Instead, he supports deductive reasoning as empirically scientific. Deductive systems avoid many of the pitfalls of metaphysical thinking and psychologism by requiring continued testing for falsifiability.
