I want to know the answer to the following question:
Which two important psychologists did Popper view as advancing non-scientific theories?
All the background I'm provided with is that "Popper puzzled over the stark contrast between the non-scientific character of Freud and Adler's theories in the field of psychology and the revolution set off by Einstein's theory of relativity in physics in the early 20th century.". Is that enough to answer the question?
