Brecht on the Truth about Fishermen and Taxmen

Adepts at seeing what goes on below the surface.

"Deep, the student, came to Mr. Keuner, the thinking man, and said: 'I want to know the truth.'
'Which truth? The truth is well known. Do you want to know the truth about the fish trade? Or about the tax system? If, because they tell you the truth about the fish trade, you no longer pay a high price for their fish, you will never know the truth,' said Mr. Keuner."
