Well done. You've made it a gang of four !
Events, common experiences, even subjective ones, either do happen or they don't.
Oh yes ...?
Listen to the climax of Rodrigo's Concierto de Aranjuez.
Julian Bream's version differs from that of John Williams by the emotional impact of a slight variation of the length of silence
before the the final chord.
Now what do you think "the event" is ? .....the silence?...the length of silence?...the juxtaposition of the lengths of silence...the emotional impact of the silence....or... THE SELECTIVE ACT OF A HUMAN OBSERVER IN DEFINING WHAT CONSTITUTES "AN EVENT" ?
Now you are talking about perceptions...but real perceptions don't imply any less objective reality.
First, the use of "selective" right there would provide an entire evening of debate as to "select" implies an act of deliberate conscious choice, a debatable hot topic per se.
Second, while perceptions report real subjective experiences that others might not be aware off, lack of knowledge of what you or anyone else experiences doesn't make it any less real that a factual experience did happen to someone at some point. Awareness, knowledge, or lack of it, on what happens to others is not a criteria to counter the scope of reality.
Real, refers to both what happens inside peoples minds own subjective experiencing and perception, as to what happens regarding others experiencing all the same. The fact that it happens
to everyone no matter how different makes it ultimately objective.
That is to say, it is objectively true that subjective experiences exist. They are real. Now the catch is they do not need to encompass all that it is real so to define the scope of what reality is in reference to myself ! Disagreement about what is real is disagreement about factual different experiencing going on from subject to subject, not about lack of real, factual, actual, experiences...
It seams to be the case that there is some good degree of concordance in describing loosely the scope of experiencing socially speaking. But even if there wasn't, a lack of a rational conducting the succession of events from person to person wouldn't make reality as a whole, any less real !
In very simple terms, to say that reality is relative amounts to say that what happens to others is not real. Depending on the point of view I just happen to be one of the "others" to whom reality is not happening...silly !
