Indeed, you go so far as to regard what is “mental” as identical with what is “conscious” – that is, with what is known to you – in spite of the most obvious evidence that a great deal more must constantly be going on in your mind than can be known to your consciousness. Come, let yourself be taught something on this one point! […] Turn your eyes inward, look into your own depths, learn first to know yourself! Then you will understand why you were bound to fall ill; and perhaps you will avoid falling ill in the future.
