Time in the View of Islamic Philosophers and Theologians

One of the most important philosophical problems which has been discussed and explored in both physics and theology is time. A few theologians have considered time to be a non-existent entity and an illusion. However, those theologians and philosophers who view time as an existential entity have presented various theories regarding the way of its existence and its truth. A group of theologians believe that time is an illusory thing, that is, it lacks an objective referent in the outside but has an origin of abstraction. Nevertheless, those who attribute an objective existence to time can be divided into two groups: some consider it to be an immaterial substance, and some others believe that it is a material and corporeal substance. However, the dominant theory holds that time enjoys an objective existence under the category of “quantity”; in other words, it is a “non-static continuous quantity” which is equal to the amount of motion in a sense, and the number of motion in another sense. Time measures the amount of motion over a specific distance. In fact, the relation of time to motion is similar to the relation of mathematical body to physical body. As a mathematical body grants determination to the ambiguous dimensions of a physical body, time also determines the amount of motion. Among all thinkers, Mulla Sadra treats this issue more meticulously and introduces time as the fourth dimension of material existents. This paper analyzes the various views of Muslim philosophers and theologians regarding time.
