Who would not be fascinated to know what his life will be like in 15 years? Yet time will satisfy our curiosity about the future so slowly that we will never gain much pleasure from learning the outcome. To quench my curiosity now, I travel back in time instead of forward. My present life is the future secret that some self of a prior decade longed to look into, and now I know the outcome and need only recall the curiosity. I imagine myself in high school wondering whom I would marry, where I would live after college, and what my job would be, so that I can pull the curtain of time and flood my remembered ignorance with insight. My accurate and failed predictions equally fascinate me: I am, and am not, who I planned to be.
The mind is a phasic receptor, only noticing a sudden stimulus. We are unconscious of who we've become because we became who we are too gradually. Forgetting is a trick for remembering.
