Root Cause of "the lack of concentration for worthy ends"

And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

Eccl. 12:12

 

"One of the chief causes of mental inefficiency and moral weakness is the lack of concentration for worthy ends. 

We pride ourselves on the wide distribution of literature; but the multiplication of books, even books that in themselves are not harmful, may be a positive evil."

E.G.W.
