According to Newton, there is only one universal and all-embracing time - it flows at a uniform rate and is not influenced by anything. It is therefore absolute and objectively the same throughout the universe[3]. Leibniz opposed Newton's theory by maintaining that time is the order of succession of events occurring in the world - without the world (events) there can be no time[4]. George Berkeley also objected that without a mind to perceive motion, the very idea of time becomes a mere illusion.
