George Bernard Shaw

Science is always wrong. It never solves a problem without creating ten more.

We don`t stop playing because we grow old; we grow old because we stop playing.

The reasonable man adapts himself to the world. The unreasonable one persists in trying to adapt the world to himself. All progress depends on the unreasonable man.

When a man wants to murder a tiger he calls it sport; when the tiger wants to murder him he calls it ferocity.
