	Contrast	Variation	Distribution
Particle	1.View the unit as an isolated, static entity. What are its contrastive features that differentiate it from similar things and identify it?	4.View the unit as a specific variation of a concept or category. What is the range of variation? How much can it change without becoming something else?	7. View the unit as part of a larger context. How is/should it be classified? What position in a sequence? In space/geography? In a system of classes?

In particular, what is its nucleus or essence?	5.View the unit as a dynamic process. How is it changing?	8.View the unit as part of a larger dynamic context. How does it interact with and merge into its environment? Are its borders clear-cut or indeterminate?
Field	3.View the unit as an abstract multi-dimensional system. How are its components organized in relation to one another (for example, in class, temporal sequence, space)?	6. View the unit as a multi-dimensional physical system. How do particular instances of the system vary?	10. View the unit as an abstract system within a larger system.
