Perceptual scales are expanded beyond kinesthesia by conversion of time into space, such as by clocks and calendars. Remembered time differs from perceived time in being dependent on awareness, which makes it episodic, fragmentary, and subject to large variations in rates of time lapse in the flow of meanings. The attribution of causal agency to objects and events in the world results from anthropomorphization in accordance with the neural mechanisms of the internal perception of intentional action. Each of us experiences passage and change, but in a way that is unique, because we see our shared world through eyes and minds that belong to us alone. Whatever time may be, it is beyond complete comprehension but not completely beyond comprehension.
Circular time has no end.
Yet it is finite. We are born without awareness, and we emerge into the theater of consciousness in the rhythm of seconds, hours, days, and years, each following the next and coming full circle with hourly ringing of the bell, nightly prayers, solstices, equinoxes, and one's annual birthday party. The cycles seem endless, yet they are broken, and the thought that breaks them, and sets our awareness on the backward path of nostalgia, is the emergent prediction that each of us will die. Hereby with awareness comes linear time, a line segment, still finite, with a beginning in birth and an ending in death, time the juggernaut that indifferently takes from us all that we have. Ancient theologians distinguished between worldly time, chronos, and eternal time, kairos, which was thought to crystallize during portentous events such as miracles and divine births.
