Summary of Karl Popper's The Logic of Scientific Discovery

Please note: This is a companion version & not the original book. Book Preview:

#1 The task of the logic of scientific discovery is to analyze the method of the empirical sciences. The methods of the empirical sciences are the steps that a scientist takes to test his hypotheses.

#2 The problem of induction is the question of the validity of universal statements based on experience, such as the hypotheses and theoretical systems of the empirical sciences. People believe that the truth of these universal statements is known by experience, but it is clear that an account of an experience can only be a singular statement and not a universal one.

#3 The principle of induction is a universal statement that is accepted by the whole of science. However, this does not mean that it is known from experience. The attempt to base the principle of induction on experience leads to an infinite regress.

#4 The work of the scientist is to put forward and test theories. The initial stage, the act of conceiving or inventing a theory, seems to me to be neither susceptible of nor calling for logical analysis.
