"it always amazes me how people go from being madly in love to nothing at all"
from the film "2 Days in Paris"
Ah, the laws of Eros (aka Cupid), the difference between "love" and "being in love".
Many aspects of our lives can, at least partially, be analysed via logic and rational analysis, the "laws" of logic. But the emotional-irrational dimension is present in them, all of them, even that is supposed to be hard for someone who was trained in "Decision Sciences" and business to admit. After all, how many of the rational decision making models that are included in the science of Economics are able to simulate or predict human consumer behavior?
But "in love", the affairs of Eros - Cupid is, for sure, not one of them. When one talks of "real" In Love, which IMO is based "purely" on emotion, logic, rationales, and decision sciences get thrown out of the window.
IME philosophy and humor can help us "deal" with the results of In Love, but not to analyse or understand it.
On the other hand, how many of the "I love you" or "I am in Love with you" allegations are actually "genuine", in other words not co-determined based on "utilitarian" (and this rational) parameters? How many people search for a love interest using the same decision parameters as when they search for an apartment or to invest their money (in this case their life)? Oh well!
