At right is a version of Rubin's vase, after its inventor / discoverer the Danish psychologist Edgar Rubin. The Vase is classified as an 'optical illusion'; it's based on / emerges from 'flip-flopping' between figure and ground. We humans are supposed to be good at pattern-matching and pattern-making, which in turn implies we're good at integrating as well as differentiating --- making wholes out of parts as well as breaking wholes into parts. And in general doing all the stuff that's beloved of Gestalt psychologists.
A 'gestaltish' perspective is one in which both trees and forest are identified and evaluated appropriately, ie within their respective contexts. Gestaltish thinking minimises the risk of category error and agency (subject/object) confusion.
