again from unseen academicals of Sir Terry Pratchett:
Nutt: „Why did you tell me not to open the book?“
Ladyship: „Because I wanted you to read it! You had to find out the truth for yourself. That is how we all find the truth.“
Nutt: „And if the truth is terrible?“
Ladyship: „I think you know the answer to that one.“
Nutt: „The answer is that, terrible or not, it is still the truth!“
Ladyship: „…and then?“
Nutt: „And then the truth can be changed.“
