Few can be induced to labor exclusively for posterity; and none will do it enthusiastically. Posterity has done nothing for us; and theorize on it as we may, practically we shall do very little for it, unless we are made to think we are at the same time doing something for ourselves.
We are seeing, then, that our experience is altogether momentary. From one point of view, each moment is so elusive and so brief that we cannot even think about it before it has gone. From another point of view, this moment is always here, since we know no other moment than the present moment. It is always dying, always becoming past more rapidly than imagination can conceive. Yet at the same time it is always being born, always new, emerging just as rapidly from that complete unknown we call the future. Thinking about it almost makes you breathless.
One cannot walk down an avenue, converse with a friend, enter a building, browse beneath the sandstone arches of an old arcade without meeting an instrument of time. Time is visible in all places. Clock towers, wristwatches, church bells divide years into months, months into days, days into hours, hours into seconds, each increment of time marching after the other in perfect succession. And beyond any particular clock, a vast scaffold of time, stretching across the universe, lays down the law of time equally for all.
If spring came but once a century instead of once a year, or
burst forth with the sound of an earthquake and not in
silence, what wonder and expectation there would be
in all the hearts to behold the miraculous change.
For age is opportunity no less Than youth itself, though in another dress, And as the evening twilight fades away The sky is filled with stars, invisible by day.
See the minutes, how they run,
How many make the hour full complete;
How many hours bring about the day;
How many days will finish up the year;
How many years a mortal man may live.
