Wittgenstein: 100 Years Of Solitude

In 1913, Ludwig Wittgenstein decided to move to Norway, and live in a remote lodge and think about stuff for a bit.
After he told Bertrand Russell, Bertie wrote;

I said it would be dark, 
and he said he hated daylight. 
I said it would be lonely, 
and he said he prostituted his mind talking to intelligent people. 
I said he was mad, 
and he said God preserve him from sanity.
