And Donald

In 1983, Popper and Miller published in Nature a new argument against inductive probability. There followed, the next year, a discussion of the validity of the argument in the pages of the same journal involving Good, Jeffrey, and Levi as well as Popper and Miller themselves. This has led in turn to still further discussions of the argument. Those who are critical include Redhead (1985) and Dunn and Hellman (1986); and those who are in favour Gillies (1986). The present interchange on the subject originated from a meeting of the two authors at a conference. The discussion which started there was continued by letter, and the two authors then decided to present their cases for and against the Popper-Miller argument in a kind of dialogue. Gillies begins in the next section by presenting one form of the argument. This is then criticized by Chihara in Section 3. Gillies repfies in Section 4, and Chihara concludes the discussion in Section 5.
