source of ignorance is bliss

who could be so wise to come up with such a saying?

This is the ending line of Thomas Gray, Ode on a Distant Prospect of Eton College.

From the tone of the ode, certainly it is full of sorrow and conflicts. i think i am far happier than that depicted in the ode.

he also says its folly to be wise. Oxymoron. So if to be wise is folly, then if one is a fool, its because he is wise?

Whatever.
