I’m not sure that kitsch “conforms itself to the knower” as much as Kaplan proposes. Propaganda is often kitschy; it conforms itself to the spectator in order to persuade the spectator — presumably to believe something that the maker thinks they don’t already believe. Noel Carroll’s _Mass art_ defends popular art, if not kitsch, against the kinds of characterization of it Kaplan offers.

The term “kitsch” is loaded with social implications: kitsch is typically aimed, for example, at a middle or lower-middle class audience. Pachelbel’s canon rapidly became kitsch when it was used at everyone’s wedding. I don’t think there’s much point in speculating about hormones in that case. Some anime looks kitschy to me, but does it look that way to its intended audience? Does Japanese aesthetics include a notion akin to kitsch? Kitschy images may hook into genetically (partly) determined dispositions, but I doubt that kitsch itself (as opposed to cuteness) admits of a biological explanation.

Back to infinity: immortality — eternal life — is perhaps the first “infinite” most of us encounter. Infinite time seems to precede infinite space among our ideal conceptions.
