[Lewin formally defines a Gestalt as:] a system whose parts are dynamically connected in such a way that a change of one part results in a change of … - Kurt Zadek Lewin

After this first approximation, the various aspects of the situation undergo a more and more detailed analysis. In contrast to this the second method [for analysis of life space] begins with the life space as a whole and defines its fundamental structure. The procedure in this case is not to add disconnected items but to make the original structure more specific and differentiated. This method therefore proceeds by steps from the more general to the particular and thereby avoids the danger of a "wrong simplification" by abstraction.

[Life space was defined as] the totality of facts which determine the behavior (B) of an individual (or group/organization) at a certain moment. The life space (L) represents the totality of possible events. The life space includes the person (P) and the environment (E). B = f(L) = f(P.E)

The outlook of a Bruno, a Kepler, or a Galileo is determined by the idea of a comprehensive, all-embracing unity of the physical world. The same law governs the courses of the stars, the falling of stones, and the flight of birds. This homogenization of the physical world with respect to the validity of law deprives the division of physical objects into rigid abstractly defined classes of the critical significance it had for Aristotelian physics, in which membership in a certain conceptual class was considered to determine the physical nature of an object.
