    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.
