In the history of philosophy, we cannot encounter any systematic explanation of the concept of time until Plato’s and Aristotle’s writings. While Plato dealt with time in a mythological context, Aristotle, approached it more rationally, bringing out the interrelation between movement, change, and time. In Augustinus, apart from the Greek’s view, there is an effort to develop an approach to time that was based upon theological convictions independent of movement (change). After giving an explanation of the ‘before,’ concerning the question of “What was God doing before creating the World?” Augustinus sets out to inquire into the partial nature of time: How can a thing exist, while some other parts of it do not (yet) exist? He pays attention to the opposition between time and eternity. Even if it is a second- degree reality (because it was created), time exists and its existence depends upon it being elapsed or continuously diminished. Questioning the special position of the now in this diminution, he comes to the conclusion that its existence is nowhere other than in the mind, as memory, attention and expectation. The past exists as the now already gone in the memory, the future exists as the now not yet in expectation; the now in intention or attention, i.e., in the mind.
