Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology, epistemology, and character of space and time. Plato, in the Timaeus, identified time with the period of motion of the heavenly bodies, and space as that in which things come to be.
Augustine’s Confessions, he ruminates on the nature of time, asking, “What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not. In contrast to ancient Greek philosophers who believed that the universe had an infinite past with no beginning, medieval philosophers and theologians developed the concept of the universe having a finite past with a beginning, now known as Temporal finitism. An infinite temporal regress of events is an actual infinite. An infinite temporal regress of events cannot exist. A traditional realist position in ontology is that time and space have existence apart from the human mind.

Idealists, by contrast, deny or doubt the existence of objects independent of the mind. In 1781, Immanuel Kant published the Critique of Pure Reason, one of the most influential works in the history of the philosophy of space and time. Arguing against the absolutist position, Leibniz offers a number of thought experiments with the purpose of showing that there is contradiction in assuming the existence of facts such as absolute location and velocity. The example Leibniz uses involves two proposed universes situated in absolute space. The only discernible difference between them is that the latter is positioned five feet to the left of the first. The example is only possible if such a thing as absolute space exists.
Such a situation, however, is not possible, according to Leibniz, for if it were, a universe’s position in absolute space would have no sufficient reason, as it might very well have been anywhere else. Leibniz’s arguments is the bucket argument: Water in a bucket, hung from a rope and set to spin, will start with a flat surface. As the water begins to spin in the bucket, the surface of the water will become concave. If the bucket is stopped, the water will continue to spin, and while the spin continues, the surface will remain concave. In this response, Clarke argues for the necessity of the existence of absolute space to account for phenomena like rotation and acceleration that cannot be accounted for on a purely relationalist account. Leibniz describes a space that exists only as a relation between objects, and which has no existence apart from the existence of those objects. Motion exists only as a relation between those objects.
Newtonian space provided the absolute frame of reference within which objects can have motion. In Newton’s system, the frame of reference exists independently of the objects contained within it. These objects can be described as moving in relation to space itself. Another important figure in this debate is 19th-century physicist Ernst Mach.
While he did not deny the existence of phenomena like that seen in the bucket argument, he still denied the absolutist conclusion by offering a different answer as to what the bucket was rotating in relation to: the fixed stars. Mach suggested that thought experiments like the bucket argument are problematic. If we were to imagine a universe that only contains a bucket, on Newton’s account, this bucket could be set to spin relative to absolute space, and the water it contained would form the characteristic concave surface. But in the absence of anything else in the universe, it would be difficult to confirm that the bucket was indeed spinning. Mach argued that, in effect, the water experiment in an otherwise empty universe would remain flat.
