7.4 Topics and Decades
So far I’ve broken down the years by what I’ve called eras. These are helpful because they feature equal numbers of articles, and if you squint the right way they correspond to philosophically significant periods. But most people are more familiar with decades than with any kinds of eras like this. (Having the first era end in 1945 was fortuitous, but otherwise they are a bit arbitrary.) So I thought I’d run all the tests from the previous three sections with decades rather than eras as the underlying unit. Start with the 90 topics broken down by which are the most popular and the least popular topics in each decade. (As above, I’m using weighted sums of articles as the main measure here.)
|Psychology||Psychology||Life and Value||Life and Value||Ordinary Language||Ordinary Language|
|Life and Value||Life and Value||Ordinary Language||Ordinary Language||Definitions||Life and Value|
|Ordinary Language||Ordinary Language||Psychology||Other History||Life and Value||Methodology of Science|
|Other History||Other History||Other History||Psychology||Methodology of Science||Definitions|
|Ordinary Language||Ordinary Language||Ordinary Language||Ordinary Language||Ordinary Language||Ordinary Language|
|Meaning and Use||Meaning and Use||Arguments||Arguments||Arguments||Composition and Constitution|
|Verification||Verification||Sets and Grue||Justification||Justification||Arguments|
|Idealism||Sets and Grue||Promises and Imperatives||Theories and Realism||Composition and Constitution||Norms|
|Definitions||Promises and Imperatives||Verification||Truth||Reasons||Justification|
That’s mostly not that interesting. Idealism is the big story early, then the two ‘topics’ that are really more styles or techniques than topics - Ordinary Language and Arguments - are the big stories later. It is a bit interesting that some things come up a decade or two after the time I associate them with. I did not expect Sets and Grue, or Verification, to be the big stories of the 1970s. But this is just a story that we’ve seen a few times now; philosophical debates don’t burn out, they just fade away.
Let’s quickly look at the bottom of these lists, remembering that these are very noisy measures especially in the early decades.
|Norms||Belief Ascriptions||Formal Epistemology||Population Ethics||Formal Epistemology||Abortion and Self-Defence|
|Population Ethics||Models||Models||Formal Epistemology||Population Ethics||Belief Ascriptions|
|Cognitive Science||Population Ethics||Quantum Physics||Belief Ascriptions||Cognitive Science||Formal Epistemology|
|Sense and Reference||Quantum Physics||Population Ethics||Models||Belief Ascriptions||Cognitive Science|
|Models||Races and DNA||Belief Ascriptions||Cognitive Science||Abortion and Self-Defence||Frankfurt Cases|
|Population Ethics||Cognitive Science||Vagueness||Psychology||Psychology||Psychology|
|Wide Content||Population Ethics||Wide Content||Races and DNA||Beauty||Heidegger and Husserl|
|Abortion and Self-Defence||Vagueness||Races and DNA||Functions||Heidegger and Husserl||History and Culture|
|Cognitive Science||Wide Content||Game Theory||History and Culture||History and Culture||Beauty|
|Game Theory||Races and DNA||Cognitive Science||Beauty||Faith and Theism||Faith and Theism|
The first table is almost all noise. In the first five columns, all of the topics listed have fewer than 1 article in each of the decades. The model getting confused by the words in one short article matching keywords of a later topic is enough to move off this list.
The second table is a bit more interesting. The model really doesn’t think we started talking about semantic externalism until the 1980s. I’ve mentioned this a couple of times now, and it really surprises me. And I thought at least some Cognitive Science work was getting going by the 1970s, though perhaps it just wasn’t turning up in these journals. In the last two decades, the relative erasure of traditional aesthetics and philosophy of religion from the twelve journals is quite striking. I thought in the 2000s the model would have been confused enough by Sleeping Beauty papers to have seen more aesthetics articles. It’s perhaps possible things went the other way, and actual aesthetics articles were mixed up with formal epistemology.
It’s a bit more interesting, I think, to look at the top of these tables after normalisation. So these tables rank the topics by what percentage of the works in that topic are in each decade. (Again, it’s weighted sum of articles that I’m using as the main underlying measure. And I’m normalising by the weighted sum of articles in each topic over the decades covered, i.e., 1890-2010, not over the whole study from 1876-2013.)
|Psychology||Idealism||Idealism||Idealism||Idealism||History and Culture|

|Self-Consciousness||Self-Consciousness||Life and Value||Psychology||Propositions and Implications||Dewey and Pragmatism|
|Emotions||Life and Value||Self-Consciousness||Physicalism||Early Modern||Beauty|

|Dewey and Pragmatism||War||Feminism||Egalitarianism||Reasons||Norms|
The early decades are not much of a surprise. The big topics from those years are big in every decade, with slightly more attention paid to history as we get into the 20th Century.
Early Modern hits a high point in the 1930s before Ryle stops it appearing in Mind.
The founding of Philosophy and Phenomenological Research makes Heidegger and Husserl particularly prominent in the 1940s.
And there is a sudden burst, especially in Journal of Philosophy of attention both to philosophy of History and Culture, and to Aesthetics. Unlike the attention to pragmatism and other distinctively American fields, these two topics don’t disappear in the earyl 1950s, but they do slow down rapidly.
Wittgensteinian philosophy turns up in the middle of the century, just like you’d expect.
And then one that is a surprise to me: Feminism having its distinctive decade be the 1970s. Looking back, especially at Ethics, there was a bit more feminist philosophy published then than in later decades. Before doing this project, I had a mental picture of Anglophone analytic philosophy being very hostile to feminist work, and this very very slowly breaking down over the last few decades. This looks a bit like evidence against that view, so let’s dig a little deeper into where these articles are coming from. Here is a list of the articles from the 1970s that the model gives a probability of at least 0.4 of being in Feminism.

Four things about this list jump out. One is that a lot of these articles are very short. If I’d weighted by pages not by articles, the topic probably wouldn’t have turned up on this list. A second is that these articles are as much about race as about gender. That’s not too surprising; a lot of philosophers still talk as if “race-and-gender” is a single word. And the model reflects that. A third is that there are a lot of men on this list. And a fourth is that the median topic here is how awfully bad affirmative action is, and how it’s really just as bad as the discrimination it is supposed to remedy. To be fair, a number of philosophers (including some of the men) are replying to this argument. But it’s a bit special how much more interested philosophers got in discrimination once affirmative action became a live possibility.
I’ll end this section with a quick look at the topics that have the lowest percentages of their works in a particular decade. Since there are many topics in any decade with practically zero works, this is a very noisy measure.

Most of that is noise, but the one thing that jumps out is the low position of “Other History” in the 1970s and 1980s. There was less and less history in these journals over time. But even within the space allocated to history, the focus got really narrow for a while I think things have gotten a little better in recent years, and especially after the end of this study, but for a while it was a striking gap in the literature.
