I am trying to remember name of a famous author. I think he is famous for writing a book on sociology or  some subject in humanities at the age of sixteen. As far as I remember, upon writing this book, his fame reaches the king of England, and he invites him to a party given his honor. But this famous author's father raised him very sternly, did not allow him to play, forced him to only study. He may be learnt Greek or Latin in a very young age. What could be the name of this author? Do not include the following keywords: england, humanity, party, father
