a week, a month, a season, a decade, when the children have grown up, or their children's children. An important part of wisdom is the ability to distinguish the time-conception that properly belongs to the thing in hand. The person who uses the wrong time-conception ranges from the dreamer who ignores the present to the philistine who can see nothing else. A true scale of values has a very acute sense of relative time.
Distant time, past and future, has somehow to be conceived. But as James says, "of the longer duration we have no direct 'realizing' sense." [Footnote: Principles of Psychology, Vol. I, p. 638.] The longest duration which we immediately feel is what is called the "specious present." It endures, according to Titchener, for about six seconds. [Footnote: Cited by Warren, Human Psychology, p. 255.] "All impressions within this period of time are present to us at once. This makes it possible for us to perceive changes and events as well as stationary objects. The perceptual present is supplemented by the ideational present. Through the combination of perceptions with memory images, entire days, months, and even years of the past are brought together into the present."
