The intro paragraph, I think, is trying to use this to its advantage by describing an unfamiliar political landscape with conservatives and parlimentarians and Stalinists and "putschists" (what even is that word?). I barely know what conservativism means as distinct from "whatever the American Republican party does". I clicked on the article because I've observed that liberalism/conservativism/libertarianism/socialism/populism/marxism/fascism/neo___ism/etc. are bandied about more like sports team names to be cheered or derided rather than comprehended, and hoped to understand this phenomenon better.
I'll push through the article eventually, with frequent dictionary lookups for "societas civilis" and "diptych" and "affairs curricula". But it's clearly written for an expert in political philosophy and will take me a long time to do so. I'm an expert in computer engineering and pretty innately talented at understanding that, I'm not an expert in the social sciences and they don't come easily to me. But I still live in a society, and try to participate in its governance as best I can...while neither journalists nor public education have really helped me to get there. I don't observe my peers reading Chomsky, Hayek, Putnam, Piketty, Turchin, and Zinn before they go to the voting booth, but they get one vote each just the same.
I've actually looked it up and found that my local community college offers a "PL230 - Introduction to Political Theory" course, this winter it's held mid-day for full-time students but they're offering it virtually in the evenings next summer so that people who work during the day can participate.
