«For the human mind absolute continuity of motion is inconceivable. The laws behind any motion become comprehensible to man only when he breaks that motion down into arbitrarily selected units and subjects these to examination. But at the same time this arbitrary sub-division of continuous motion into discontinuous units is the cause of much human error.(...)The movement of humanity, arising from a countless series of actions arbitrarily performed by many individuals, is a continuous phenomenon.» (War and Peace)
