  Meinong points out that the temporal properties of the objects we perceive need not coincide with the temporal properties of the presentations (or episodes of awareness) in which we apprehend them: e.g., objects which are past can be presented in the present. A further distinction concerns ‘temporally distributed’ and ‘temporally undistributed’ objects. An entity is temporally distributed if its existence is spread over time, it is temporally undistributed if its existence is confined to a single moment. It is natural to think that a temporally distributed process such as a melody is perceived via a sequence of presentations which are themselves temporally distributed – presentations which run concurrently, or in parallel, with what is presented. However, this natural or naïve picture is also problematic: since a succession of presentations does not amount to a presentation of succession, something further is needed. For Meinong, as for Brentano, the way forward is dictated by a necessary constraint on experienced unity: for contents to make up a perceived succession they must be presented simultaneously, to a single momentary act of apprehension. So it turns out that, contrary to the naïve view, temporally distributed objects are apprehended by episodes of experiencing which are themselves non-distributed.
