In his investigations about temporality, Edmund Husserl often faces the matter of imagination, which leads him to question the relation between time and the constitution of the so-called objects of phantasy (Phantasiegegenständen). If, according to phenomenology, time plays a primordial role in the act of constitution of the objects of the real world, will temporality have this same importance for the constitution of imaginary objects? With that question in mind, Husserl carries out an analysis of the act of phantasy, which is the act that constitutes the imaginary objects.
In his inquiry the philosopher will define phantasy in contrast to the perception by placing the latter as the limit between the real object and the imaginary object. This comparison will show that temporality precisely appears once again as a phenomenological core, for it will be the primordial aspect in the distinction between perception and phantasy.
