If there was no change and things were standing still, life would be very monotonous. If the sea were always calm and there were no tides, if the sun neither rose nor set and the moon was always the same, if it was always summer or winter and we ourselves stood still in the same conditions of life all the time, life would not be of interest to us. it would be worse than death and we could not endure it. Why? Because it would not be nature, for nature means change.
