 Because we say not only that we perceive a color, a sound, an act of seeing, an act of hearing, but also that we perceive the existence of an act of seeing or of an act of hearing, someone might be led to believe that perception, too, consists in the acknowledgement [Anerkennung] of the conjunction of the attribute “existence” with the phenomenon in question. Such a misunderstanding of obvious facts seems to me almost inconceivable. (PES 210 [II 51–52; SVS 1, 232])
