fantasies have to be unrealistic

What is it that you fantasize about? World Peace? Thought so...Do you fantasize about international fame? Do you fantasize about Pullitzer Prize? Or a Nobel Peace Prize? A MTV Music Awards? Do you fantasize about meeting some genius hunk? Ostensily bad, but secret simmering, with noble passion and willing to sleep on the wet spot?
You get Lacan´s point: fantasies have to be unrealistic. Because the moment, the second that you get what you seek, you don´t, you can´t want anymore. In order to continue to exist, desire must have its objetcs perpetually absent. It´s no the "it" that you want, is the fantasy of "it". So desire supports crazy fantasies. This is what Pascal means when he says: "we are only trully happy when daydreaming about future happiness". Or why we say: "the hunt is sweeter than the kill". Or: "Be careful what you wish for". Not because you will get it, because doomed not want once you do. So the lesson of Lacan is: living by your wants will never make you happy. What really means for be fully human is to strive for living by ideas and ideals and not measure your life by what you attained in terms of desires but those small moments of integrety, compassion, rationality...even self sacrifice. Because in the end, the only way we can measure the significance of own lives...is by valuing the life of others.
