Wolfgang Held introduces the diverse small and large rhythms that shape our lives: from the smallest rhythmic units in the range of seconds to the grand cosmic structures of the Platonic year. Just as humans have learned to orient themselves more consciously in space, they can seize entirely new developmental opportunities in the conscious orientation within the cosmos of time. How long does a moment last? Why is the future always part of the present? What is the significance of the time between the years? Why does the new day actually begin in the evening? When are we best able to discover new questions? Why do we all feel a bit tired every four hours? How long can we truly remain attentive in one stretch? What does the number 7 have to do with time? Why is there a difference between thinking about something in the evening or in the morning?.
