When one has a belief, one is thereby related to a proposition. Thus, for example, if one believes that the universe is expanding, one stands in a certain psychological relation, the relation of believing, to the proposition that the universe is expanding. One is also related to this proposition if one fears that the universe is expanding or one hopes that the universe is expanding. In general, propositions are the objects to which we are related by the family of psychological relations that includes believing, fearing, hoping, desiring, intending, and considering.

We often claim that a proposition is true. Thus, we are all prepared to say that the proposition that snow is white is true. I will be concerned in this work to explain what we have in mind when we make such claims. That is to say, I will be concerned to analyze the concept of propositional truth. In addition, I will be concerned to adjudicate the various disputes about this concept that have traditionally divided philosophers.

To the extent that these efforts are successful, they will, I believe, illuminate the entire fabric of our thought and talk about truth.
