The future is open: a conversation with Sir Karl Popper
ADAM CHMIELEWSKI: Sir Karl, please accept my best wishes on the occasion of your ninety-second birthday.1
SIR KARL POPPER: Thank you very much. CHMIELEWSKI: Sir Karl, despite your quite impressive age, you are a very
active philosopher. Could you tell me, what you are working on now in philosophy? Are you still developing your system?
