Knowledge is knowing the objective truth. In order for knowledge to exist there first needs to be an objective truth that we are trying to know.For example in the physical world there is a concrete truth that can be knowable. However in metaphysical things get more vague. Then we need a container to contain the information, like the brain or mind. Although animals may have a smaller brain than human they can still have an instinctual knowledge, an innate knowing without recognizing or being able to reflect on the knowing. Us humans also have some innate knowledge that may be unknown to us, and we are not aware of it. The idea that Carl Jung spoke about that there is a collective unconscious is that in our unconscious there lies loads of information however the knowledge is beyond our awareness. In the lesson fivewe explained two ways of obtainingknowledgea priori and a posteriori. A priori means without any experience based on logic and reason. While a posteteriori is based on practical experience.However there may be a third way Having knowledge and that is similar to Plato’s ideaofbodies being a reflection of higher forms. Plato stated that "…the true substances are not physical bodies, which are ephemeral, but the eternal Forms of which bodies are imperfect copies. This concept is Similar Carl Jung’s idea of collective unconscious. Jung in his book “The Archetypes and the Collective Unconscious (London 1996) p. 43 writes; “The collective unconscious does not develop individually but is inherited. It consists of pre-existent forms, the archetypes, which can only become conscious secondarily and which give definite form to certain psychic contents.” I the Book“Man and his Symbols “(London 1978) p. 57 “Jung linked the collective unconscious to 'what Freud called "archaic remnants" – mental forms whose presence cannot be explained by anything in the individual's own life and which seem to be aboriginal, innate, and inherited shapes of the human mind.
