I discovered this website not so long ago and it is fascinating: www.lettersofnote.com
As the name suggests, it’s a collection of letters that may be interesting to someone, you, perhaps.
“February 12, 1950
Dear Mr. Marcus:
A human being is a part of the whole, called by us “Universe”, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion. Not to nourish the delusion but to try to overcome it is the way to reach the attainable measure of peace of mind.
With my best wishes,
You can pledge for a book of the letters over at Unbound (the crowd funding site for books) which I intend to do once I have a bit of spare cash.
I have already pledged for the Warhorses of Letters book which, if Tall Tales and the Radio 4 show are anything to go by, should be fun. There’s a website for this here. The notebook thing is very cool, if illegible.
