A BASIS FOR THE REALITY OF ABSOLUTE SPACE
According to the absolutist approach, space has its own existence independently of things inhabiting it. Leibniz, who is a relationalist about space, constructs strong arguments against the existence of absolute space. His arguments derive from that the notion of absolute space contradicts two basic principles: The Principle of Sufficient Reason, and the Principle of Identity of Indiscernibles. On the other hand, Kant provides a substantial argument against relationalism. According to Kant, the notion of “incongruent counterpart” cannot be explained in terms of a relationalist account of space. We, therefore, need to posit absolute space to explain the difference between incongruent counterparts. In this study, I aim to present Leibniz’s and Kant’s arguments respectively in order to see which notion of space is more plausible. It is claimed that, even though the Kantian argument does not necessarily falsify relationalism, it nevertheless constitutes an important challenge against it.
