Ecclesiastes 1:8-18

8 All things are full of weariness; a man cannot utter it; the eye is not satisfied with seeing, nor the ear filled with hearing.
9 What has been is what will be, and what has been done is what will be done; and there is nothing new under the sun.
10 Is there a thing of which it is said, "See, this is new"? It has been already, in the ages before us.
11 There is no remembrance of former things, nor will there be any remembrance of later things yet to happen among those who come after.
12 I the Preacher have been king over Israel in Jerusalem.
13 And I applied my mind to seek and to search out by wisdom all that is done under heaven; it is an unhappy business that God has given to the sons of men to be busy with.
14 I have seen everything that is done under the sun; and behold, all is vanity and a striving after wind.
15 What is crooked cannot be made straight, and what is lacking cannot be numbered.
16 I said to myself, "I have acquired great wisdom, surpassing all who were over Jerusalem before me; and my mind has had great experience of wisdom and knowledge."
17 And I applied my mind to know wisdom and to know madness and folly. I perceived that this also is but a striving after wind.
18 For in much wisdom is much vexation, and he who increases knowledge increases sorrow.
