And I gave my heart to seek and search out by wisdom concerning all which is done under the heavens. It is a sad task God has given to the sons of men to be humbled by it.
There is one alone, and there is not a second; yea, he has neither son nor brother; yet there is no end to all his labor; and his eyes are not satisfied with riches; and he says , For whom do I labor and take good from my soul? This is also vanity. Yes, it is an evil business.
I set my heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness;
All this I have seen, and I gave my heart to every work that is done under the sun. There is a time in which one man rules over another to his own hurt.
