One of the prominent arguments that arose from the correspondence between Newton's spokesman Samuel Clarke and Leibniz is referred to as the bucket argument, or Newton's bucket.

It is simply the way in which humans subjectively perceive and sequence the objects, events, and experiences accumulated throughout their lifetimes. Within this argument, known as relational time, time itself cannot be measured. According to Leibniz, time is nothing more than a concept similar to space and numbers that allows humans to compare and sequence events. Newton's realist view is sometimes referred to as Newtonian time.Ĭontrary to Newton's assertions, Leibniz believed that time only makes sense in the presence of objects with which it can interact. Relative time on the other hand, is what humans actually perceive and is a measurement of 'duration' through the motion of objects, such as the sun and the moon. He argued that absolute time exists and flows without any regard to external factors, and called this 'duration.' According to Newton, absolute time can only be understood mathematically, since it is imperceptible. In Newton's Philosophiæ Naturalis Principia Mathematica, Newton tackled the concepts of space and time as absolutes. Aristotle's view is solely one amongst many in the discussion of time, the most controversial of which began with Sir Isaac Newton, and Gottfried Leibniz. Interestingly, he was also one of, if not the first person to frame the idea that time existing of two different kinds of non-existence, makes time existing at all, questionable. He also believed that time was infinite and continuous, and that the universe always did, and always will exist.

One of the earlier views was presented by the ancient Greek philosopher Aristotle (384-322 BC), who defined time as 'a number of movement in respect of the before and after.' Essentially, Aristotle's view of time defined it as a measurement of change requiring the existence of some kind of motion or change. There exist various concepts of time that have been postulated by different philosophers and scientists over an extensive period of human history. Oct., Dec.-31 daysįeb.-28 days for a common year and 29 days for a leap yearĢ4 hours or 1,440 minutes or 86,400 seconds The following table shows some common units of time. However, due to how time is defined, there exist differences in how calculations must be computed when compared to decimal numbers. Like other numbers, time can be added or subtracted.
