Thanks to the phenomenological analyses that we have undertaken, we now understand the origin of modalizations arising in the sphere of perception. We find modal distinctions purely with respect to the objective sense of every perception, and the same perceptual object can potentially present itself one time in this modality, another time in that modality, or in variable modalities, now as existing in pure and simple certainty, now as problematically possible in conflict with other problematic possibilities, and then as not existing or as existing in fact. On the other hand, the perceptual object is inconceivable without one of the modalities we just mentioned, just as it is inconceivable without open possibilities, since the perceptual object moves into an open future. If we go from the noematic attitude to the noetic one, the perceptual lived-experience will likewise be inconceivable without what makes up the modalizing accomplishment in the perceptual lived-experience; and this is completely clear to us.
