The short version is that metaphysics is at worst flat in every journal, and rising rapidly in Analysis, Philosophical Quarterly and Philosophy and Phenomenological Research. That’s fine, but shouldn’t we see positivism showing up somewhere the put downward pressure on metaphysics at least somewhere? If that happens, it isn’t visible in the journal-level data. What happens at the topic-level?
So there are two big topics - Modality, and Composition and Constitution - that only take off after positivism goes away. The same is probably true of Causation as well, but it’s much smaller. I was surprised that causation was so much smaller than the other very modern categories; maybe that’s in part because some of the causation work ended up getting classified as philosophy of science.
But we still haven’t answered the question about where positivism shows up. I thought that the graph here would be U-shaped, with lots of metaphysics either side of a positivism-driven dip in the middle. We can recreate that gap if we declare that all the work in idealism is really metaphysics.
That’s more like what I expected, though the post-positivism rise is much smaller than the pre-positivism fall. It obviously looks different if you use counts rather than proportions.
And now we’re back to a steady rise, with no obvious place to locate the rise of positivism.
I think the big story here is that positivism has much less impact on the journals than you might think from the standard story about the history of 20th century philosophy. If you give positivists credit for killing idealism, then it has an enormous influence. But I’m not sure what the case is for that. It’s not like Moore was a card carrying positivist, and he surely had something to do with the downfall of idealism.
Anyway, let’s keep track of this when we look at subsequent topics, because it would be very surprising to see no impact from positivism on the literature.
