Remembering and reverie: Those who do not remember the past are condemned to repeat it.
—GEORGE SANTAYANA
Living in the present means not just paying attention to what goes on around us, but realizing that present awareness includes memories of the past and anticipation of the future. Those who fail to live in the present (figuratively, that is; it is impossible to live elsewhere) and attempt to live in the past cannot distinguish between memory as part of present experience and memory as a retreat to a past more real than the present.
