Memos by Paul Meehl

Verisimilitude

                     It makes a fellow cheery
                     To be cooking up a theory;
                     And it needn't make him blue
                     That it's not exactly true
                     If at least it's getting neary.

                                       —Meehl, 11/7/1988

Memo: Meehl to Herbert Feigl (1976/1993). Prolegomena to post-positivist ethics.

In 1976 Paul Meehl sent Herbert Feigl (his teacher, friend, and colleague in the Philosophy Department and the Minnesota Center for Philosophy of Science) this memo outlining his thinking about ethics. He continued to read and think about the questions of ethics through subsequent years, but Meehl always regretted that he couldn't “solve ethics” to his own satisfaction.
