On October 25, 1946... in a small crowded room at Cambridge University, two of the world’s greatest twentieth-century philosophers, Ludwig Wittgenstein and Karl Popper, came face-to-face for the first and only time.

To this day, no one can agree precisely what took place in those fiery minutes. Almost immediately, rumours started to spread around the world that the two philosophers, Wittgenstein and Popper, had come to blows armed with red-hot fire pokers!
