Matter, in its widest sense, is the possibility of form; form is the actuality, the finished reality, of matter. Matter obstructs, form constructs. Form is not merely the shape but the shaping force, an inner necessity and impulse which moulds mere material to a specific figure and purpose; it is the realization of a potential capacity of matter; it is the sum of the powers residing in anything to do, to be, or to become. Nature is the conquest of matter by form, the constant progression and victory of life.
