"The word "belief" is a difficult thing for me. I don't believe. I must have a reason for a certain hypothesis. Either I know a thing, and then I know it - I don't need to believe it"

Carl Jung's quote speaks with his apprehension and his demand for proof prior to accepting something as true. He is stating that he does not count on something just because it is stated to be true, however instead he needs to have a factor for a particular hypothesis. He is indicating that he does not take things at stated value, yet rather he needs to have proof to support an insurance claim before he can accept it. This speaks with his analytical and also rational strategy to life, as he is not willing to accept something without proof. He is additionally suggesting that he does not rely on something just because it is claimed to be real, but instead he needs to have a factor for a certain theory. This quote talks to his requirement for proof as well as his sensible approach to life, as he is not happy to accept something without proof.
