Ecclesiastes 2:3, 12

I searched in my heart how to gratify my flesh with wine, while guiding my heart with wisdom, and how to lay hold on folly, till I might see what was good for the sons of men to do under heaven all the days of their lives.

Then I turned myself to consider wisdom and madness and folly; For what can the man do who succeeds the king?— Only what he has already done.
