I rather liked these two entrees from Josh Chafetz on Oxblog - part I and part II, as it were. One is always intrigued by parallels between pure science and pure fiction. Together they make perfect sense. And so conclusions from fiction:
But this is the deep strength of Love and Friendship: It isn't sound bite-able. It talks around the issue, not directly at it, because the nature of love, like most of the really important issues, can't be reduced to a formula. Sometimes the most accurate way to talk about something is to be ambiguous, perhaps even somewhat contradictory. The desire for precision can be the enemy of truth as well as its facilitator.
resonate well with science, or at least with the uncertainty principle1
