Problematic Nature of Views This answer states that:


  View are mental constructions as they break down under scrutiny at a lower level of abstraction. Since an average person cannot discern the realities at lower levels of abstraction some view and confidence in these view.


I am confused by this, because I understand the world in terms of views, I have the feeling most people hold on to views. If these views aren't existent, what are people holding on to? I agree that perhaps these views are illusory, as they are impermanent and dependently originated, but doesn't the fact we recognize them imply they have some reality and existence?

More so, when I write for myself I often get insights, but these insights form aggregated beliefs. They're precisely aggregated, abstract ways of seeing things. Does Buddhism precisely condemn this as a cause to suffering?

Lastly, the quote mentions lower levels of abstraction. Wouldn't most people usually live in such levels, and fail to reach higher levels of abstraction?
When we say "level of abstraction" we don't mean "level of sophistication", but rather "how much generalization this abstraction entails". "High level of abstraction" means a birds-eyes-view with a lot of generalization. "Low-level of abstraction" means we look at particulars.

For example, when we say "In US, Democrats are generally good people, and Republicans are generally more pragmatic than ethical."  -- that's a high level of abstraction, not high level of sophistication.

Most people hold these kind of very general views about things, very much simplified. In fact, the nature of MIND is such that it has tendency to forming and holding on to such simplified views. Children are known for this, as well as unsophisticated adults. Mahayana Buddhists say that "reifying" (grasping as real) such views is the root of suffering. Buddha said, the Highest of the two Right Views (the right view without asavas vs the right view with asavas) is "analysis of dharmas" - meaning, the ultimate right view is to go beyond simplified views and reifyed abstractions.

Why?

Because simplified views omit too much, they are "leaking abstractions", thereby creating potential for mental conflict, which is the nature of suffering.

How do they create potential for mental conflict?


Either two (groups of) people hold opposing simplified views on the same ontological subject, and therefore come in conflict with each other. OR
A person grasps at a simplified view and comes in conflict with REALITY when the details omitted in the simplified view inevitably come up. (One obvious example is Impermanence - i.e. we grasp at an idea of an entity as something fixed, while the reality beyond this simplified abstraction is an assembly of transitory aggregates. Impermanence is just one example of leaking abstraction though, out of million other cases.)


To summarize, grasping at views, specifically grasping at "abstract", "generalized", "simplified" views, and specifically assuming them to be THE ontological reality must be recognized as the root of suffering.
