Experiencing is the appearing of things, or the happening of events, ‘before’ they are designated as things, events, (ideas, images, people, places, processes, …..). Experience then is the appearance of phenomena – the noun forms here signalling that some‘thing’ has been identified as a single event or entity in the ongoing, undifferentiated stream of experiencing. This formulation or ‘reification’ is a necessary step toward discourse or dialogue.
Experience itself does not appear; it is the channel through which things appear or happen. Afterwards, though, we call a remembered appearance or happening an experience.
