Kant is the pupil of Hume. As Hume had thought the world external to us could not give us knowledge of relations but only of particulars and contingencies, Kant asserted that any supposed knowledge of universality and necessity had to be a priori . The various forms of idealism, Leibnizian, Kantian, Fichtean, and others have not advanced beyond being as determinateness, have not advanced beyond this immediacy, any more than scepticism did. In the Doctrine of Being, Hegel thinks Being immediately as it is, is in itself. The particulars and contingencies, or better, individuals constitute the sphere of Being.
Prices go up and down, politicians have scandals, strikes, take-overs, elections, etc.
This is Being. There is a relation between the categories of Being which are necessarily involved in the attempt to think it. Nevertheless, there is not order between individual things and all relations are external. Measure is implicitly Essence Determinations of individuals, in the first instance, are either quantitative or qualitative. Neither quality nor quantity is, however enough in themselves for individuality, there is a third determinations in their unity, which is measure.
