Abstract:I will describe the logics of a range of conditionals that behave like conditional probabilities at various levels of probabilistic support. Families of these conditionals will be characterized in terms of the rules that their members obey. I will show that for each conditional, \to, in a given family, there is a probabilistic support level r and a conditional probability function P such that, for all sentences C and B, ‘C\to B’ holds just in case P[B\mid C]\geqslant r. Thus, each conditional in a given family behaves like conditional probability above some specific support level.
