 Hartshorne develops the concept of dual transcendence by drawing a distinction of logical type between, on the one hand, an individual’s existence and enduring characteristics and, on the other hand, the actual states of the individual. Using an example dear to his ornithological interests, Hartshorne says, “That I shall (at least probably) exist tomorrow is one thing; that I shall exist hearing a blue jay call at noon is another” (Hartshorne 1962, 63). The logical relationship between the two sentences “I shall exist tomorrow” and “I shall exist tomorrow as hearing a blue jay call at noon” is that the second cannot be inferred from the first, but the first can be inferred from the second. The relation of entailment between the sentences is a function of the information provided in them. Both sentences speak of the individual’s existence, but only the second sentence speaks of the experience that the individual is having. Hartshorne argues that this logical relation between the sentences reflects an ontological difference between the bare fact of one’s existence and the actual states in which one exists. Existence, says Hartshorne, is abstract compared to actuality, which is the concrete. What is true of existence is also true of one’s defining or enduring characteristics. The state of affairs described by “Hartshorne existing as an ornithologist” is abstract compared to the state of affairs described by “Hartshorne existing as an ornithologist hearing a blue jay call at noon.” The more abstract statement leaves more details concerning the individual’s actuality to be defined. Unless strict determinism is the case—which would require that there is only one future that is genuinely possible—the ornithologist can exist tomorrow without hearing a blue jay call at noon (perhaps he will hear another bird, or none at all).
