Gay Science 327
Taking Things Seriously.

The intellect is with most people an awkward, obscure and creaking machine, which is difficult to set in motion: they call it "taking a thing seriously" when they work with this machine wanting to think well - oh, how burdensome must good thinking be to them! That delightful animal, man, seems to lose his good humor whenever he thinks well; he becomes "serious" !

"Where there is laughing and gaiety, thinking cannot be worth anything"
- so speaks the prejudice of this earnest animal against all "Gay Science"

- Well, then!
We shall show that it is prejudice!
