In kohler’s opinion 1920, in the physical world one can observe
many different systems that tend to evolve dynamically according to a minimum
principle, towards a state of equilibrium, in which their energy level is as
low as possible. The prototypical example of such “physical Gestalten” is given
by the soap bubbles. In other word, Kohler was pointing out the presence of
physical gestalten in nature, such for example, as the tendency of
electrostatic charges always to distribute or “shape” themselves in a way that
would produce an equilibrium of forces over the surface or a conductor.
One can change the strength of the charge in any way one
wishes (and summation) without in any way altering this instantaneous tendency
to assume the characteristic configuration.
