Firstly, the equipment was different in terms of category, quantity and running time between operation and design stages, leading to considerable underestimate of energy consumption at the design stage.
When it comes from the matter, then the predicate falls into the second category, quantity [quantitas].
He resolves this matter by combining three of the Aristotelian categories: quantity, relation and, finally, quality.
There Kant articulates what he calls "pure natural science" in four chapters corresponding, respectively, to the four headings of the table of categories (quantity, quality, relation, and modality).
But several authors also argued for the identification of relations with their foundations, that is to say, for the identity of the significata of relative terms with the significata of terms in the categories quantity and quality.
Strictly speaking, only the things which I have mentioned belong to the category of quantity: everything else that is called quantitative is a quantity in a secondary sense.
It is important to recognize that, in calling the referents of the defined terms "quantities," Newton is assigning them to the ontological category of quantity in Aristotle's sense.
So, a second question about Aristotle's category of quantity naturally suggests itself: how can body be a species in both the category of quantity and the category of substance?
In this way, he tries to show that the category of quantity, like that of substance, has an ordered internal structure, and he reasserts the reality and real distinction of quantity against authors such as Peter Olivi and Ockham, who had attempted to reduce quantity to an aspect of material substance.
We have already seen that on the question of the status of the category of quantity, then at the border of logic and physics, Albert followed Ockham and distanced himself from Buridan by reducing quantity to a disposition of substance or quality.
