Time in Avicenna's nature philosophy: Essence and elements of it's

Time the most intricate issue of the history of philosophy was considered as a number of movement by Aristotle and this understanding brought with it some enigmas. The original position of Avicenna on the problem of time was formed to solve these enigmas and led the philosopher to the need to define time as a magnitude rather than number. Although both philosophers describe time as both number and magnitude, Avicenna's predeccessors set up the problem with the concept of "number"; Avicenna, on the other hand, brought the concept of magnitude to the fore and pushed the concept of "number" into the background. This thesis aims to determine in which subjects Avicenna's bases time as a magnitude. In addition, the study is detailed with topics such as how the problem of time is examined in physics, the nature of the connection between motion and time, everlasting and now.
