Hi Ken,
You are mistaken. AND you are referring to a different source. I referred to Poppers 1976 book with its sections on the three worlds focusing on theory and evidence (the topic of the discussion). You are referencing a lecture with a completely different purpose, human values.
In fact, if you had read the original, you would have appreciated that when Popper is writing about airplanes and the like in the lecture you referred to he does so in terms of 'abstract objects' (line 15 p148 Tanner Lectures) with abstract objects being objects as of the mind - what most people on this list would call designs - rather than the physical objects themselves that he regards as of world 1 or the experiences of them, which he regards as belonging to world 2.
In reality, however, simply reading the lecture should have led you to different conclusions.
In that lecture, Popper is clear to distinguish (as I described) between the physical version of an object and its different existence as an object in the experience world (world 2) , or the abstract object or theory world 3. For example, ' Many of the objects belonging to world 3 [theory world] belong at the same time also to the physical world 1. Michelangelo’s sculpture The Dying Slave is both a block of marble, belonging to the world 1 of physical objects, and a creation of Michelangelo’s mind, and as such belonging to world 3 [theory world].' In this, Popper is distinguishing between David's design in mind and the physical statute itself.
Even in this lecture, which has a very different purpose to the Unended Quest book, Popper uses the three worlds' model in exactly the same way that I described. Perhaps you could recheck your analysis?
Best regards,
Terry

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.
