The Is–Ought Gap / Axiology

Arriving from the other side

The previous inquiry ended at a wall: no fact about what we are yields a conclusion about what we should value. That was biology reaching its limit. Now we stand on the far side of the same wall and ask the question it forces — not “why can’t facts give us values?” but “then what can?”

There are exactly three families of answer, and every theory of value is a variation on one of them. It is worth seeing them laid out plainly, because most people hold one without knowing they have chosen.

Answer one: ought reduces to is

The first move is to deny the gap. Perhaps “good” just means some natural fact — what we desire, what promotes flourishing, what a well-functioning organism pursues. If so, values are facts after all, and ethics is a branch of natural science.

The attraction is obvious: it keeps value inside the world science can study. The difficulty is the one Moore pressed. For any natural fact you name — this is what we desire — it remains an open, sensible question to ask, “but is it good?” If “good” simply meant “desired,” the question would be closed, a mere repetition. It never is. That stubborn openness is evidence that value is not just a fact wearing a value’s clothes.

Answer two: ought is an illusion

If value cannot be reduced to facts, perhaps there are no values — only facts, plus our feelings projected onto them. The error theorist says our value-talk systematically misfires: when we call cruelty wrong, we assert something objective, and there is nothing objective there to make it true. Nihilism, in its disciplined form.

This is harder to refute than it is to believe. It accounts neatly for moral disagreement and for the absence of values from the physical inventory of the universe. And yet no one lives it. The nihilist still resents betrayal, still prefers their child’s life to a stranger’s convenience, still thinks gratuitous torture is not merely disliked but wrong. A theory that no one can inhabit even for an afternoon has, at minimum, failed to describe something real.

Answer three: ought is real but non-factual

The third answer keeps value real while granting that it is not a fact among facts. Value is not out there like mass and charge, waiting to be measured; nor is it nothing. It is a different kind of thing — something that arises in the relation between a valuing creature and a world, irreducible to either alone.

Value is neither a fact we discover with our eyes closed nor a fiction we invent from nothing. It is what happens when a certain kind of being meets a certain kind of world.

This is the answer this inquiry will follow, not because the other two are stupid — they are serious, and they press real difficulties — but because it is the only one that preserves both of the things we cannot honestly give up: that value does not float free of minds, and that it is not merely made up.

Why the choice matters

This is not a parlour distinction. Which answer you hold quietly determines everything downstream. If value reduces to fact, then enough measurement settles every question of worth, and the technocrat is right. If value is illusion, then power is the only real currency and persuasion is just manipulation that worked. If value is real but non-factual, then there is something to get right that no instrument can read off the world for you — and the work of a life is partly the work of getting it right.

The rest of this topic takes the third path and asks the questions it opens. The first is the most basic of all: if value is neither a worldly fact nor a private fiction, then where, exactly, does it come from?
