Mauthner's “Critique of Language”
But now he also wants to move on to answering the question of how to achieve culture again. What must be done to achieve culture again? He then asks: What must the culture we achieve be like? — And he says: It must be ethical and optimistic. Now, imagine you want to build a house for yourself. You go to a builder who says: You have to describe to me what the house should be like so that I can make the plans for you. — So you tell him: The house should be solid, weatherproof, beautiful, and so that you can live comfortably in it. — Well, you can't make plans with that, but you think you have said something when you say: The house must be solid, weatherproof, beautiful and so that you can live comfortably in it. But you can't do anything with these statements. Nor can you do anything with the statement: A worldview must be ethical and optimistic. It's the same, exactly the same.
