Where is the past?

"...the metaphor "the passage of time is motion:" one is "time passing is motion over a landscape" (or "moving-ego"), and the other is "time passing is a moving object" ("moving-events"). The latter metaphor does not explicitly involve the individual/speaker; events are in a queue, with prior events towards the front of the line. The individual may be facing the queue, or it may be moving from left to right in front of him/her."

"...conceptualize the ego as moving forward into the future, with ego's back to the past... encode the past as in front of individuals and the future behind them"

"...the past is visible to us (in front of our eyes) while the future is not."
