 According to Twardowski, it is not possible to present all the parts of an object in a presentation. Given that the number of parts of an object is boundless, and that we can only present a finite amount of characteristics, the number of the elements of the content is therefore lower than that of the parts of the object (§12, 78–9; on this point Twardowski is again indebted to Bolzano (Wissenschaftslehre, §64). It follows that no adequate presentation is possible of any object (§13, 83).
