What does it mean to be curious?

A fascinating article over at the Chronicle of higher education explores Curiosity:
Curiosity, Dillon proposes, is a way of knowing that looks askance. It draws attention to the unexplained or overlooked fragment, to invite us, if possible, to look sideways and look closely at the same time. As such, its promise of knowledge is ambiguous. Does curiosity seek to unmask the strangeness that absorbs its attention, or is it an invitation to luxuriate in that strangeness? Does it carry an inherent Baconian injunction to go further and illuminate, or does it recommend the alternative pleasures of not knowing? “Enigma lies at the core of the curious experience,” Marina Warner comments in a short essay included in Curiosity, “epiphany should not reveal all.” So is curiosity a wake-up call or a waking dream?
