"Ectoplasm is cosmic goo"

I've been reading up on ectoplasm and found this great essay in the Cabinet Magazine archives. An excerpt:

Ectoplasm is shapeless, it is "informe," a kind of primordial paste—and to show itself as this, it annexes semiotic markers that designate intermediate spirit worlds. When looking at these fluid, inchoate forms, sometimes imprinted with a face, it is worth recalling that the word larva, used in English for the early stage of a caterpillar, meant "ghost" or "specter" in Latin, but is also used by Horace to designate a mask, such as might frighten an observer, while the verb larvo meant "to bewitch" or "enchant." Ectoplasmic masks are indeed larval: they promise the emergence of forms, but don't deliver them.

Yes yes, very interesting.
