⁹To clarify and recapitulate: We can define desire in different ways on the hot-cold axis. In the coldest definition, desire is simply a preference for some states, essentially just another way of saying that some states are rewarding or have higher state-values. You might say, for example, that you want to see Kyoto one day, but saying that does not necessarily arouse any feelings, and launch any deliberations in your brain. A slightly less cold definition says that desires propose goal states for a planning system, thus possibly launching computations to attain such a state. The definition in the elaborated-intrusion theory is quite hot, emphasizing the interruptive quality of those computations. An even hotter definition, not pursued here in detail, might further add a subjective, conscious experience of burning with desire, but this is outside of the computational modelling framework we take here, and presumably only applicable to humans and higher animals. — To emphasize the difference between different kinds of desire, such a “hot”, compelling desire is sometimes called occurrent desire, while the kind of cold, long-term rational desire that simply expresses a preference is called standing desire. I prefer to talk about “interrupting” desire instead of occurrent.
