Jerzy Grotowski said this quote

“ So always avoid banality. That is, avoid illustrating the author's words and remarks. If you want to create a true masterpiece you must always avoid beautiful lies: the truths on the calender under each date you find a proverb or saying such as: He who is good to others will be happy. But this is not true. It is a lie. The spectator, perhaps, is content. The spectator likes easy truths. But we are not there to please or pander to the spectator. We are here to tell the truth. ”
