Subjectivism, Material Synthesis and Idealism

In this chapter, I show that there is at least one crucial, non-short, argument, which does not involve arguments about spatiotemporality, why Kant’s subjectivism about the possibility of knowledge, argued in the Transcendental Deduction, must lead to idealism. This has to do with the fact that given the implications of the discursivity thesis, namely, that the domain of possible determination of objects is characterised by limitation, judgements of experience can never reach the completely determined individual, i.e. the thing in itself or the unlimited real, but only objects as objects of possible experience. As such, it can be shown by reference to a key argument from Kant, that Hegel’s famous criticism that Kant is not licensed, on the basis of his core arguments concerning the original-synthetic unity of apperception, to restrict our knowledge to appearances, is mistaken on purely systematic grounds. More specifically, I argue that idealism follows already from the constraints that the use of the categories, in particular the categories of quality, places on the very conceivability of things in themselves. My claim is that, although it is not only possible but also necessary to think things in themselves, it does not follow that by merely thinking them we have a full grasp of the nature of things in themselves, as some important commentators claim we have. We must therefore distinguish between two kinds of conceiving of things in themselves: conceiving in the standard sense of ‘forming the notion of’, and conceiving in the narrow sense of ‘having a determinate intellectual grasp’. So although we must be able notionally to think things in themselves, as the grounds of their appearances, we cannot even conceive, through pure concepts, of how they are in themselves in any determinate, even if merely intellectual, sense. To put it differently, we cannot have a positive conception of things in themselves (this is in line with Kant’s distinction between noumena in the negative and positive senses; cf. B307–9). For support, I resort to a much overlooked chapter in the Critique, concerning the transcendental Ideal, where Kant discusses what it is for a thing to be a thing in itself proper, namely, something that is thoroughly determined. This concerns the real ontological conditions of things, which are not satisfied by the modal categories alone, namely, their existence conditions. I claim that the chief reason why, given Kant’s view of determinative judgement, we cannot determine a thing in itself is because of two connected reasons: (1) a thing in itself is already fully determined and therefore not further determinable and (2) we cannot possibly determine all of the thing’s possible determinations. In this context, I also discuss the notion of material (not: empirical) synthesis—of which Kant speaks in the chapter on the transcendental Ideal—which must be presupposed as the ground of the formal a priori synthesis that grounds possible experience. This material synthesis, which is an idea of reason that defines a thing as thoroughly determined with regard to all of its possible predicates and has mere regulative status, can by implication not be determined by the forms of the understanding, which synthesise only a limited set of predicates. As a result, given this definition of ‘thing in itself’, any object (appearance) as at best44 a limited set of determinations of the thing can never be numerically identical to the thing in itself as thoroughly determined individual. This undercuts a standard assumption about the identity relation between appearances and things in themselves in many contemporary interpretations of Kant’s transcendental idealism

Repliek op de kritiek van de Boer, Blomme, van den Berg en Spigt

In this article, I respond to critiques of my book Kant’s Radical Subjectivism: Perspectives on the Transcendental Deduction (London: Palgrave Macmillan, 2017). I address issues that are raised concerning objectivity, the nature of the object, the role of transcendental apperception and the imagination, and idealism. More in particular I respond to an objection against my reading of the necessary existence of things in themselves and their relation to appearances. I also briefly respond to a question that relates to the debate on Kantian nonconceptualism, more in particular, the question whether Kant allows animals objective intentionality. Lastly, I respond to one objection against my reading of Hegel’s critique of Kant. (The copy uploaded here is an English translation of the original Dutch version that is published in the journal.

Diet uniformity at an early farming community in northwest Anatolia (Turkey) : carbon and nitrogen isotope studies of bone collagen at Aktopraklik

Aktopraklık is a settlement site composed of three areas (A–C) in the Marmara region of northwest Anatolia, with phases of occupation that date to the Late Neolithic and Early Chalcolithic periods, mid-seventh to mid-sixth millennium bc (ca. 6400–5600 cal. bc). Here, we present 54 human and fauna bone collagen stable isotope results from the site, alongside five modern fish bone collagen isotope results, to examine the nature of human diet. The stable isotope analysis shows that human diet comprised the consumption of select C3 terrestrial resources, with a preference for domestic animal proteins over plant proteins. The evidence to date suggests that animal husbandry was at the forefront of Late Neolithic and Early Chalcolithic subsistence practices. No isotopic difference in humans is observed between biological sex or between areas B and C at the settlement

Further isotopic evidence for seaweed-eating sheep from Neolithic Orkney

The antiquity of the practice of grazing on and/or foddering with seaweed is of interest in terms of understanding animal management practices in northwest Europe, where provision had to be made for overwintering. Orkney holds a special place in this discussion, since the sheep of North Ronaldsay have been confined to the seashores since the early nineteenth century, and are entirely adapted to a diet consisting mainly of seaweeds. Here, we report the results of stable carbon and nitrogen isotope analysis of twenty-five faunal specimens from the Neolithic chambered tomb of Quanterness, Orkney. Three of the 12 sheep analysed show elevated δ13C values that can only be explained by the consumption of seaweed. Radiocarbon dates place two of the three animals in the Neolithic, coeval with the use of the monument for burial, while the third animal dates to the Chalcolithic/Early Bronze Age. The findings are placed into the wider context of previous isotopic analyses of domestic fauna from prehistoric Orkney. A possible disjoint is noted between the results for bone collagen – where seaweed consumption seems to relate to the pre-natal period, since all the animals with high δ13C values are less than ca. three months of age – and previous studies using high-resolution sequential enamel measurements, which suggest a repeated pattern of winter consumption of seaweed in older animals.</p

Marine radiocarbon reservoir effects for the Mesolithic and Medieval Periods in the Western Isles of Scotland

This article presents new values for the Scottish marine radiocarbon reservoir effect (MRE) during the Mesolithic at 4540–4240 BC (6490–6190 BP) and the Medieval period at AD 1460–1630 (490–320 BP). The results give a ΔR of –126±39 14C yr for the Mesolithic and of –130±36 14C yr for the Medieval. We recalculate previously published MRE values for the earlier Holocene in this region, at 6480–6290 BC (8430–8180 BP). Here, MRE values are slightly elevated, with a ΔR of 64±41 14C yr, possibly relating to the 8.2ka BP cold event. New values for the Mesolithic and Medieval indicate lower MRE values, broadly consistent with an existing data set of 37 mid- to late Holocene assessments for Scottish waters, indicating stable ocean conditions. We compare the intercept and probability density function (PDF) methods for assessing ΔR. The ΔR values are indistinguishable, but confidence intervals are slightly larger with the PDF method. We therefore apply this more conservative method to calculate ΔR. The MRE values presented fill important gaps in understanding Scottish marine 14C dynamics, providing confidence when calibrating material from critical periods in Scotland’s prehistory, particularly the Mesolithic, when the use of marine resources by coastal populations was high

Dates, Diet, and Dismemberment: Evidence from the Coldrum Megalithic Monument, Kent

We present radiocarbon dates, stable isotope data, and osteological analysis of the remains of a minimum of 17 individuals deposited in the western part of the burial chamber at Coldrum, Kent. This is one of the Medway group of megalithic monuments – sites with shared architectural motifs and no very close parallels elsewhere in Britain – whose location has been seen as important in terms of the origins of Neolithic material culture and practices in Britain. The osteological analysis identified the largest assemblage of cut-marked human bone yet reported from a British early Neolithic chambered tomb; these modifications were probably undertaken as part of burial practices. The stable isotope dataset shows very enriched & 15N values, the causes of which are not entirely clear, but could include consumption of freshwater fish resources. Bayesian statistical modelling of the radiocarbon dates demonstrates that Coldrum is an early example of a British Neolithic burial monument, though the tomb was perhaps not part of the earliest Neolithic evidence in the Greater Thames Estuary. The site was probably initiated after the first appearance of other early Neolithic regional phenomena including an inhumation burial, early Neolithic pottery and a characteristic early Neolithic post-and-slot structure, and perhaps of Neolithic flint extraction in the Sussex mines. Coldrum is the only site in the Medway monument group to have samples which have been radiocarbon dated, and is important both for regional studies of the early Neolithic and wider narratives of the processes, timing, and tempo of Neolithisation across Britai

The Aveline's Hole 9 Cranium: A Partial Solution to a Long Standing Enigma

Aveline's Hole is both one of the best-known sites with early human skeletal material in Britain and one of the most problematic in its history. First discovered and explored at the close of the 18th century, it yielded an estimated burial count of at least fifty individuals. Twentieth century work suggested a Late Upper Palaeolithic date for the material, in a context that might be called Creswellian. A recent dating programme places the human remains into the early Holocene and confirms the site as a Mesolithic cemetery in all senses of that word. Though a number of partial studies of the material have been published, no full description was attempted or published prior to the destruction of much of the collection in 1940. Recently one of us published a full study of the site history and a description and analysis of the surviving material. However, that study did note the small number of intact but undated crania that have been attributed to the site at various times. This study looks at one of these, denoted as AH9 and never previously described, in the aftermath of direct radiocarbon dating. Both direct dating and indirect analyses indicate that it is highly unlikely that this skull was part of the Mesolithic assemblage from this site."The work of CM was made possible by grants from the Canada Council and the Social Sciences and Humanities Research Council of Canada. The dating of the specimen was funded by a grant through NERC’s ORADS programme."https://www.ubss.org.uk/resources/proceedings/vol25/UBSS_Proc_25_3_275-294.pd
