The web
Every object named here
A field says which part of the subject an essay sits in and a series follows one idea in depth. This is the third axis: the named objects themselves, and every essay that touches each one.
There are 352 named objects here, and 293 of them are named by more than one essay. Those have a page of their own. The rest link straight to the single essay that names them — a page whose whole content is one card would say nothing the essay itself does not.
