Ecclesiastes 2:11-13

11Then I considered all which my hands had done and labored to do, and behold, all was vanity and chasing after the wind and there was no profit (nothing of lasting value) under the sun.

12So I turned to consider [secular] wisdom, madness, and folly; for what will the man do who succeeds the king? Nothing except what has already been done.

13Then I saw that [even secular] wisdom [that brings sorrow] is better than [the pleasures of] folly and self-indulgence as light excels darkness.
