Pieces

Idea from reading Musicophilia, by Oliver Sacks: the requirement for sound to be architectural, in 3D, in order for an emotion to happen. If not, if all sounds feel "flat", music stops provoking feelings.
Can we extend this and say that this should apply not only to sound but to all perceptions, and that "architecture", or "3d", refers to and extends to two related characteristics of a perception: 

• its richness, hence a piece of art void of complexity (e.g. pop-art) cannot provoke much feelings, and some of the most complex work of art can provoke feelings that small works can not.
• its natural fit into our human nature. Just as our ears have been created to alert us of physical dangers, hence need to match the physical world and can't naturally express such dangers and then feelings without this match, then a piece of art cannot be felt without a minimal anthropomorphic projection into a familiar scene. 

A different thought: I was missing the feeling of family and friendship this morning, so went on Facebook,  and only saw an inarticulate forum, sparse of reality, content with unrelated self-expression. A group needs a common goal to stay solid, sharing some background past isn't enough. Religion needs goals.
