Dear All,
Without emerging from lurk mode, I invite those who wish to understand Karl Popper's views to read Popper. Terry’s account is incorrect, or at least inadequate. Popper does not speak of a “theory world” as Terry describes it. Rather, Popper (1978: 143-144) speaks of “world 3.” He describes this as a world of “products of the human mind, such as languages; tales and stories and religious myths; scientific conjectures or theories, and mathematical constructions; songs and symphonies; paintings and sculptures. But also aeroplanes and airports and other feats of engineering.”
Popper does not describe his three worlds as “incommensurate,” certainly not as Terry seems to use the term. Rather, Popper describes these worlds as interacting. He sees them as “different but interacting sub-universes” (Popper 1978: 143) within the larger universe. It is this interaction that makes evidence useful in Popper’s philosophy of science.
It is true that I did not discuss Karl Popper’s views in my lecture. It is impossible to address all these issues in a one-hour lecture. Even so, nothing in Popper’s views contradicts my position on evidence.
Read Popper for yourself.
