Success treads on every right step . For the instinct is sure that prompts him to tell his brother what he thinks . He then learns that in going down into the screts of his own mind , he has descended into the secrets of all the minds . He learns that he who has mastered any law in his private thoughts , is master to that excent of all men whose language he speaks , and of all into whose language his own can be translated . The poet in utter solitude remembering his spontaneous thoughts and recording them , is found to have recorded that which men in "cities vast" find true for them also .
