Question

What is the difference between case theory and vita theory?

Answer 1

I have searched the net but didn't find anything on case and vita theory.

Vita is defined in Encarta as a brief account of somebody's life (formal)

and case is defined as a situation or set of circumstances;  an instance or example of something;  a subject of investigation or scrutiny by a professional person; the reality or truth of a particular situation; a matter in question or a problem...

Theory is defined as the body of rules, ideas, principles, and techniques that applies to a subject, especially when seen as distinct from actual practice.

There you go.  Hope this helps.
