The problem of unity of the representations of space and time was originally put forward by H. Vaihinger. H.J.Paton holds that this unity is actually the unity of apperception, but Heidegger thinks that this unity is a kind of syndotical unity, which is prior to the unity of apperception. This article starts with the mechanism of the representations of space and time and exposes that this unity is actually the absolute unity which belongs to all kinds of intuitive representations. It comes from the construction of imagination, but this construction is based on the unity of apperception.
