Is it actually bugged or just a ridiculous in joke? Philosophy of Death ... Great big empty pages... and a guy that quizzes you on it with what seems to be a nihilistic attitude.
I had considered that the book being blank was intentional, but the questions and references made during the "quiz" are too specific, as if they are definitely referring to something the player should have read.
In the english.xml file you can find:
The Philosophy of Death
Let us briefly discuss life and death, the great opposites; the great equals.
Death is greater than life, so sayeth the priest, for in death comes the gods' just reward. But if this be true, whether that reward shall be the solace of heaven or the agony of hell is decided during one's lifetime and therefore life is much greater than death, for it is the decision maker.
And what of those who care not for the gods, who question the afterlife; the existence of deities? Life is life's own goal they say; a wise sentiment I echo, and that even priests would do well to heed. But O how often does doubt assail these revellers of life! How often does fear approach with the creeping of the shadows... So great becomes the looming horror that death becomes larger than life and death becomes the greater force.
Forget the promise of gods I say, but defy the fear of oblivion as well, for only if life and death become each other's equals can the philosophy of death become one of life. Death is the instigator of faith and fear, but only if you let it be so. If you can gaze into its obsidian eyes, knowing it is the be all and the end all, but fear neither, then shall you have reached the shores of wisdom.
So sayeth Nemris.
I wonder if reading this is supposed to trigger an advancement in the quest journal, and/or experience reward. At the moment the blank book does neither.
