Since a rational man's ambition is unlimited, since his pursuit and achievement of values is a lifelong process - and the higher the values, the harder the struggle - he needs a moment, an hour or some period of time in which he can experience the sense of his completed task, the sense of living in a universe where his values have been successfully achieved. It is like a moment of rest, a moment to gain fuel to move farther.
