Is It Real?
----
In Buddhism, there is a lot of teaching around 2500+ year old quantum theory - some of it seems to echo the passages you selected from Wittgenstein. In particular, there is the concept that everything is composed of the things that make it up. This seems so sensible (because I worded it that way) that people accept it. Until it is applied deeply.
In the West, there is a perception that a thing exists inherently. We point at a car and say, "It exists! Step in front of it if you don't believe me!"
In Buddhism, a person might deny it exists. Not that there isn't a phenomenon labeled "car", but that the thing has any inherent existence outside being an effect of its parts. It doesn't exist independently as a thing, but rather simply an an effect of its parts. Remove a part and the car is something else. Language being what it is, we may still apply the label "car", but we are applying it to a different effect now: without the fender, it is a different effect. Close to the old one in our judgment, but undeniably different.
An interesting aside here is that the perception of the viewer is one of the parts. It is that which applies the label and so is an integral part of the identity "car."
Parts change from moment to moment. Thus, the effect they create is changed as well. The car exists for a moment, an atom spins off or a mud splash jumps in, the label is applied to this new combination of parts.
In Buddhism, the pertinence of all this is that the individual is encouraged to question the contribution of his personal filters to this process. Also, acknowledging that all things are in constant transition brings a perspective of transience to both attachments and aversions. Don't expect anything to last forever.
There does seem to be a more basic Awareness beyond the busy ego-self, but it, too, is considered to be changing as experience. For there, we would we delve into Buddhist theory of rebirth where this Awareness [energy?] survives the death of form, but not as the individually identified ego or Self of popular Western conception.)
I imagine that Wittgenstein might have been thinking along lines like these? I can't deny that a car means something different to me than it does to someone else. It is appropriate to say that my reality of a car is different from another's. And that might lead to the difference in perspective between the idealist and the realist...?
