I find myself in agreement with most of the points of Crosby's position that there are new things and new events in the world. Like him, I hold that determinists are mistaken, and I believe that time flows one way only. I appreciate Crosby's amendment of Whitehead's category of the ultimate from creativity to creativity/destructiveness or, translating Spinoza's term, nature naturing. And finally I applaud his clever, and I think successful, argument that the production of novelty, rather than being incompatible with causal action, is, indeed, a requirement for any such process. Most of the meat of philosophy, however, lies not in agreements but in their contraries. While I do have significant disagreements with Crosby, I want to state at the beginning that these deal with issues in Philosophy that I find among the most perplexing, and so I hope I can expound them with at least a modicum of clarity.
The major, underlying concern I have with Crosby's argument centers not on the concept of novelty nor on whether such occurs, but on the concept of causality. It is in relation to causality that Crosby attempts to prove his case on the existence of novelty. He maintains that not only is novelty not opposed to causality, but novelty itself is a necessary condition for causality to exist at all. Very importantly, I believe he proves his point. However, if causality is a totally confused notion, then, in my opinion, proving that novelty is necessary for causality to exist proves much less than Crosby intends. If I am correct, Crosby's argument is vitiated to a good extent because of its connection with causality at all.
To see how this plays out, we can look at the simplest statement of this principle, "Everything that exists must have a cause." But note that this tries to make causality clear by invoking the frustrating and paradoxical notion of "thing." What is a thing, which is supposed to require a cause for its existence? I present a piece of sandstone. Is it a thing? Here is a grain of sand on the surface of the piece. Is it a thing? The sandstone was taken from a ledge. Is the ledge a thing? The ledge is part of a deposit. Is the deposit of sandstone a thing? What happens to the causality principle if we try to eliminate (not an easy thing) this suspect category of thing (or something)?
Maybe it is every event that must have a cause. But this gets us no closer to freedom from metaphysical quicksand. The first definition in my dictionary of event is, "Something that happens"(emphasis mine). And if we consider the notion of event on its own ground, so to speak, we run up against the following questions, among others: How much time is necessary for an event? Is a hiccup an event? A hiccup in the middle of a concert? Was the Chicago Fire an event? The battle of Antietam? The Civil War? The settling of the West? The Industrial Revolution?
I am not concerned here with what is usually regarded as the essential puzzling issue of causality, that is, the nature of the causal relation. I am only struggling, and vainly I fear, with the preliminary issue of what the things are that are said to require causes. And I'm pessimistic that we will get very far in the task of specifying with precision just what these things—or occurrences or processes or fundamental entities or whatever—are.
Perhaps another approach, a different angle, might be utilized. Must it not be that there is a fundamental truth or insight, or at least a strong, legitimate motive for holding that every thing (or event, etc.) must have a cause? This is a position held by virtually everyone at the level of common sense, and by the great majority, even, of skeptically minded philosophers. Rather than trying either to stipulate what the entities involved in causality are or wrestle with the issue of what the causal relationship itself is, let's try to understand why the principle is so widely held—what its appeal is. The...
