Feelings are designed to encode judgments about things in our environment. Typically these judgments are about whether these things are good or bad for the survival of the organism doing the feeling (though sometimes they’re about whether these things are good or bad for close kin—notably offspring—since close kin share so many of our genes). So we could say that feelings are “true” if the judgments they encode are accurate—if, say, the things they attract the organism to are indeed good for it, or if the things they encourage the organism to avoid are indeed bad for it.
