BGE231. Learning alters us but at the bottom of our souls, quite 'down below,' there is certainly something unteachable, a granite of spiritual fate, of predetermined decision and answer to predetermined, chosen questions. In each cardinal problem there speaks an unchangeable 'I am this"; a thinker cannot learn anew about man and woman, for instance, but can only learn fully - he can only follow to the end what is 'fixed' about them in himself. Occasionally we find certain solutions of problems which make strong beliefs for us; perhaps they are called 'convictions.' Later on - one sees in them only footsteps to self-knowledge, guide-posts to the problem which we ourselves ARE - or more correctly to the great stupidity which we embody, our spiritual fate, the UNTEACHABLE in us, quite 'down below.' - You are a dwelling place but that place is shaped in a way that is unique to you & which does not change. Understanding Nietzsche is not easy !!!
