Everybody knows that if and because1 are related conjunctions. Goodman (1954, p. 14) takes Because A? to be equivalent to its" contrapositive", the subjunctive conditional statement If?\B then?\A2, and Ryle (1963, p. 317) sees at least a truth conditional equality between Because AB and the subjunctive conditional statement//?\A then~ if?. The common belief, I think, is already found in Ramsey (1931, p. 248), who mentions If p then q and Because pq in the same breath stating" because is merely a variant on//when p is known to be true". Beginners in philosophy can already learn much the same from Blau's highly esteemed propaedeutics (1982, 1983, p. 43, my trans? lation):" Closely related to//, are the partial truth functional operators because, since, hence, therefore, etc. It seems to me they are essentially the conjunction of A and if A then JB." I would like to call the view of Ramsey and Blau the mainstream analysis of the relationship between because and if (in the following," Mainstream Analysis"). Nobody knows the exact relationship between if and because. This is strikingly documented by the difference in attention that has been paid to//and because in modern philosophy. Whereas if has gained abundant care by the meanwhile proliferating conditional logics because has remained in the shadows. I think we should do more justice to because and shall venture a parallel analysis of both conjunctions. In approaching this I won't prematurely commit myself to one of the views mentioned above. Instead I want to start with the idea that because always points to a reason or an explanation. In the next section, the basic ideas of three promising accounts of conditionals, reasons, and explanations are cited. The common feature of these accounts is that they rely on the beliefs of an epistemic subject. In section 3, I shall describe the simple model of beliefs to be used for my analysis. In section 4, the suggested analysis of conditionals (viz., the Ramsey test) is found to be inadequate in the light of the Mainstream Analysis, which points to a modification, viz., to the
