Ludwig Wittgenstein

* "A man will be imprisoned in a room with a door that's unlocked and opens inwards; as long as it does not occur to him to pull rather than push." [Attributed]

Happy birthday to the great genius who showed us the possibility of pulling the door open!

* "A serious and good philosophical work could be written consisting entirely of jokes." [Saad, this is especially for your consideration.] [Attributed]

* "The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) " [Philosophical Inverstigations]

* "To believe in God means to see that life has a meaning." [Notes from 1916]

* "The limits of my language mean the limits of my world." [Tractatus]
