FINETTI,BRUNO,DE AND THE LOGIC OF CONDITIONAL EVENTS

This article begins by outlining some of the history-beginning with br ief remarks of Quine's-of work on conditional assertions and condition al events. The upshot of the historical narrative is that diverse work s from various starting points have circled around a nexus of ideas wi thout convincingly tying them together. Section 3 shows how ideas cont ained in a neglected article of de Finetti's lead to a unified treatme nt of the topics based on the identification of conditional events as the objects of conditional bets. The penultimate section explores some of the consequences of the resulting logic of conditional events whil e the last defends it.
