Theory:

The Great Stone Face II is a fanciful short story written by Nathaniel Hawthorne that focuses on Ernest and his noble characteristics and how people perceived him as a deserving person identical to The Great Stone Face.
 
The story began with a brief description of Ernest's looks in his aged years, as well as the knowledge he had accumulated over the years. He grew into a 'Man of Excellent Qualities' due to his belief in the Great Stone Face and persistent practice of his good virtues.
 
Many people travelled from far to meet and speak with the noble person (Ernest). One of them was a poet whose work was loved by the great Ernest, leading him to believe that the poet was the human figure of the Great Stone Face. Ernest soon realised that the poet didn't look at all like the Great Stone Face. In reality, the poet amitted that, while his concepts in the poems were worthy, they were not genuine.
 
Also, when the poet observed Ernest preaching to his neighbours, he felt that those were not just words but were the words of his life. And when he compared Ernest's majestic, thoughtful face to that of The Great Stone Face, he was overwhelmed by finding a similarity between both. At that exact moment, the poet exclaimed joyfully, revealing Ernest's true identity as the prophesied person whom people had waited decades to meet. The valley inhabitants were delighted with the disclosed answer because everyone thought he was a deserving person of all ages.
 
Ernest, who was virtuous, returned home after meeting his neighbours, hoping that someone greater and wiser than him might come to the valley eventually.
