Philosophy Now Forum

I am not a professional philosopher. Can you please explain this sentence or the idea that a writer or an artist is locked in an exteriorless passion? The context is "Dostoyevsky is also conscious of the aesthetic effect of being locked in an exterior-less passion with the risk of a deathly as well as joyful closure through imaginary self-consumption, through the tyranny of the beautiful; that is perhaps what prompts him to cling violently to his religion and its principle-forgiveness." It is the most difficult for my to understand that the passion is exteriorless - why if the artist has realised themselves by creating a novel or any other creative ideal as the result of forgiveness?
