Curiosity beckons all the day, like a persistent itch, wherein scratching provides only temporary relief; were I to nurse my curiosities all the day, they should find no further relief.
Itching provides no amelioration, no mollification that delivers the attention from its incessant rapping.
The etymology is itself curious:
curious: mid-14c., “eager to know” (often in a bad sense), from O.Fr. curios “solicitous, anxious, inquisitive; odd, strange” (Mod.Fr. curieux) and directly from L. curiosus”careful, diligent; inquiring eagerly, meddlesome,” akin to cura “care” (see cure). The objective sense of “exciting curiosity” is 1715 in English. In booksellers’ catalogues, the word means “erotic, pornographic.” Curiouser and curiouser is from “Alice in Wonderland” (1865).
