Classic Poem

Two men took useless trouble and strove without any profit, when one of them accumulated property without enjoying it, and the other learnt without practising what he had learnt.

However much science thou mayest acquire
Thou art ignorant when there is no practice in thee.
Neither deeply learned nor a scholar will be
A quadruped loaded with some books.
What information or knowledge does the silly beast posses
Whether it is carrying a load of wood or of books?
