I can’t tell if Suki Finn’s Beyond Reason: The Mathematical Equation for Unconditional Love<\/a> is meant to be taken seriously or not. Irony on the internet is usually indistinguishable from earnestness. The fact that there is an addendum with a mathematical proof may indicate that it’s serious, but maybe it’s a droll bit of farce?<\/span>1<\/sup><\/a><\/span><\/p>\n\n\n

I read it with interest, in any case. Finn offers an analysis of conditional and unconditional love that is modeled on conditional and unconditional credence. As I’ve discussed in some recent<\/a> posts<\/a>, I think that recognizing the difference between conditional and unconditional value is crucial for understanding the relation between values and belief.<\/span>2<\/sup><\/a><\/span><\/p>\n\n\n\n\n\n\n\n

The conditional probability of P given Q, Pr=(P|Q), is often taken to be basic. Nevertheless, when Pr(Q) is not zero, we can calculate it from unconditional probabilities: Pr(P|Q)=Pr(P&Q)\/Pr(Q). This, along with some basic math, gets you Bayes’ theorem.<\/p>\n\n\n\n

We can treat love or utility as a function that assigns a number to a state of affairs, such that higher numbers mean better. We might write the conditional love of P given Q as Luv(P|Q) and the conditional utility of P given Q as Ut(P|Q).<\/span>3<\/sup><\/a><\/span> Unlike the case of probabilities and rational credences, however, it’s not clear that there’s any necessary relation between the conditional utility Ut(P|Q) and the unconditional utilities Ut(P&Q) and Ut(Q). At the very least, it is not usually going to be the case that Ut(P|Q)=Ut(P&Q)\/Ut(Q).<\/p>\n\n\n\n

So, although the difference between conditional and unconditional value is important, we can’t press too hard on the analogy with conditional and unconditional probability.
