The enormous collection of letters, written by Goethe. How come it has such power of attraction? Personally, I would have nothing against reading them all.
Something that creates the interest for the letters could be that they bear witness of a man always occupied with something.Goethe studies, he is exploring subjects.He gives advice.He is travelling.Even resting has the character of an interesting activity on his part.
Wonderful letters, wonderful they are so many.
