Ludwig Wittgenstein quotes
A serious and good philosophical work could be written consisting entirely of jokes. 
Nothing is so difficult as not deceiving oneself. 
The real question of life after death isn't whether or not it exists, but even if it does what problem this really solves. 
I don't know why we are here, but I'm pretty sure that it is not in order to enjoy ourselves. 
Whereof one cannot speak, thereof one must be silent. 
The limits of my language means the limits of my world. 
I am my world.
