Forms are merely excitations of material, just as particles are excitations of their respective fields. The durability of a form is dependent on the schematic and the structural, not necessarily on its actual formal characteristics except in such cases that a forms characteristics are volatile on a macroscopic level, as in the case of a bridge or building that has been improperly designed and is thus susceptible to a large and sudden modification of form. Rather than material relying on form, form relies on material. Form has a platonic supremacy as it can be conceptualized without material involvement. However, it is only due to material having previously produced form that we can conceptualize the latter and consequently believe that it precedes material. It can be said that process is the schematic by which material behaves and otherwise fluctuates given intervention or of it’s own accord.
A schematic is something more molecular than form. Whereas form is something that we still associate with material the schematic is something that is tied to the notion of material in its basest sense. The atomic structure of an element is its schematic. It is because of schematics that material realizes various characteristics that then yield to natural and man-made processes which beget form.
