The complete, abstract indifference of developed measure, that is, of its laws, can only be found in the sphere of mechanism where concrete corporeity is only abstract matter itself; the qualitative differences of this matter are of an essentially quantitative nature; space and time are nothing but pure externalities, and the aggregates of matters, the masses, the intensity of weight, are determinations which are just as external and have their proper determinateness in the quantitative element.
