A search for little philosopher lead to reading about a philosopher from a different century - John Stuart Mill. An interesting letter written by him when he was a six year old:

My dear Sir,

Mr. Walker³ is a very intimate friend of mine, who lives at No. 31 in Berkeley Square. I have engaged him, as he is soon coming here, first to go to your house, and get for me the 3.^d and 4.^th volumes of Hooke’s Roman history.⁴ But I am recapitulating⁵ the 1.^st and 2.^d volumes, having finished them all except a few pages of the 2.^d. I will be glad if you will let him have the 3.^d and 4.^th volumes.

I am yours sincerely

John Stuart Mill.

John Stuart Mill was trained rigorously by his father. Compare that to the little philosopher from Washington suburb, who they say is not trained at all.
