Beneath the surface of conscious and volitional knowledge, however, lies the twin domains of the personal and ‘collective unconscious’ or “a structural layer of the human psyche containing inherited elements, distinct from the personal unconscious”. Socrates is famous for, among other things, recognizing that one knows but knows not that one knows. Such knowledge forms part of the personal unconsciousness and the Socratic method is a traditional way of raising such knowledge to consciousness.________________________
Option (a) is correct. Taking a cue from ‘the Socratic method’, option (a) discusses the other method that is being taken up as a consequence of the discussion. Option (b) which is close seems like a repetition as collective unconscious has been explained earlier.
