The Day Existentialism was Born

There was once a philosopher who concluded an essay with the remark ... "we are all one".

The writer gave his note to the publisher and since in those days computers weren't yet invented, the editor gave the pamphlet to the type setter who got it ready for the printing press. Yet somewhere along the process something got messed up, and an "l" got dropped. When the typesetter looked at the last sentence all he saw was ..

"We are al one." 

The type setter naturally thought that there was an error with the spacing, so he changed it to "we are alone"; and that is how Existentialism's first pamphlet ever got printed. How symbolic, when you drop an "l" - for love -  our lovely state of Oneness becomes a lonely place indeed.
