How Saul Kripke might approach Philosophy

Philosophy. What is it, really? It’s not just a collection of old books, certainly. Though, some of them are quite important for understanding where we’ve gone wrong. We start with a question, don't we? Something seemingly simple. Let’s suppose we're trying to understand what it is to *know* something. What is knowledge? Descriptivists, and there are many of them, will tell you it's about having justified true belief. Seems reasonable enough. But then, we have to ask: what is it for something to be *justified*? And what does *true* even mean?

Now, let’s say I point to this particular chair. I say, "This chair is brown." How do I know it's brown? Well, it looks brown to me. You look, and you say it looks brown to you too. But what if, in another possible world, this very same chair, the one I'm pointing at, is, say, blue? Is that possible? If it is, then my saying "This chair is brown" isn't necessarily true. Its being brown might depend on how things just happen to be.

But then, consider something like water. We all know what water is, right? It flows, it quenches thirst. We can describe its properties. But is it *necessarily* H₂O? It seems to me that it is. If it turned out that what we call "water" in this world was something else entirely, say, XYZ, then this other substance, XYZ, would just be a different kind of liquid. The very *essence* of water, as we pick it out with the word "water," is its molecular structure. That's a metaphysical discovery, not an epistemic one.

So, philosophy, it seems to me, is the painstaking process of revealing these essential truths, these necessary connections, by rigorously examining how we use our words and what commitments those uses entail. It’s about distinguishing what *must* be from what merely *happens* to be.…
