For in much wisdom is much grief: and he that increases knowledge increases sorrow.
All Commentaries on Ecclesiastes 1:18 Go To Ecclesiastes 1
Augustine of Hippo
AD 430
It is evident, then, that the oldness of the letter, in the absence of the newness of the spirit, instead of freeing us from sin, rather makes us guilty by the knowledge of sin. [Thus] it is written in another part of Scripture, “He that increases knowledge, increases sorrow.” [It is] not that the law is itself evil, but because the commandment has its good in the demonstration of the letter, not in the assistance of the spirit. And if this commandment is kept from the fear of punishment and not from the love of righteousness, it is kept in a servile manner, not freely, and therefore it is not kept at all. For no fruit is good which does not grow from the root of love.
