Only those propositions which directly present the determination of an act as necessary, simply by representing its form (in accordance with laws in general), regardless of the material content of the envisaged object, can and must possess their own special principles (in the idea of freedom), and although the concept of an object of the will (the highest good) is grounded on precisely these principles, this object still only belongs indirectly, as a consequence, to the practical precept (henceforth described as a 'moral' one).
