I argue that my non-dual epistemic-phenomenalist view is the one that best harmonises my interpretation of the Fourth Paralogism with the widely shared reading of the Refutation of Idealism that I sketched and defended above. The bottom line of my view is a clear distinction between the metaphysical and epistemological sides of Kantian idealism. Again, according to my non-dual-epistemic-phenomenalism, the mundus sensibilis and mundus intelligibilis are epistemologically distinct ways of considering the metaphysically identical outside world. Appearances are nothing but the (...) way the things in themselves appear or exist inside our sensible minds as mere representations. In this sense, I reject both the two-world view, the two-aspect view, and Allais’s deflationary anti- phenomenalist reading. (shrink)

The Humility Thesis is a persistent thesis in contemporary metaphysics. It is known by a variety of names, including, but not limited to, Humility, Intrinsic Humility, Kantian Humility, Kantian Physicalism, Intrinsic Ignorance, Categorical Ignorance, Irremediable Ignorance, and Noumenalism. According to the thesis, we human beings, and any knowers that share our general ways of knowing, are irremediably ignorant of a certain class of properties that are intrinsic to material entities … Continue reading Humility Regarding Intrinsic Properties →.

I argue that Immanuel Kant's critical philosophy—in particular the doctrine of transcendental idealism which grounds it—is best understood as an `epistemic' or `metaphilosophical' doctrine. As such it aims to show how one may engage in the natural sciences and in metaphysics under the restriction that certain conditions are imposed on our cognition of objects. Underlying Kant's doctrine, however, is an ontological posit, of a sort, regarding the fundamental nature of our cognition. This posit, sometimes called the `discursivity thesis', while considered (...) to be completely obvious and uncontroversial by some, has nevertheless been denied by thinkers both before and after Kant. One such thinker is Jakob Friedrich Fries, an early neo-Kantian thinker who, despite his rejection of discursivity, also advocated for a metaphilosophical understanding of critical philosophy. As I will explain, a consequence for Fries of the denial of discursivity is a radical reconceptualisation of the method of critical philosophy; whereas this method is a priori for Kant, for Fries it is in general empirical. I discuss these issues in the context of quantum theory, and I focus in particular on the views of the physicist Niels Bohr and the Neo-Friesian philosopher Grete Hermann. I argue that Bohr's understanding of quantum mechanics can be seen as a natural extension of an orthodox Kantian viewpoint in the face of the challenges posed by quantum theory, and I compare this with the extension of Friesian philosophy that is represented by Hermann's view. -/- A shorter version of this paper, focusing specifically on the views of Grete Hermann, has been published as: Cuffaro, Michael (2023).

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. (shrink)

In quest’articolo, articolo prenderò in esame i passi in cui Kant descrive la monadologia leibniziana come un “concetto platonico” del mondo, ossia come una descrizione del mondo intelligibile che non ha nulla a che vedere con la spiegazione del mondo fenomenico. In generale, vorrei mostrare che quest’interpretazione non va contrapposta a quella che lo stesso Kant aveva dato nella prima Critica, dove la monadologia era caratterizzata come un “sistema intellettuale del mondo”. Per fare ciò, risponderò a due domande. La prima (...) riguarda le ragioni che possono aver indotto Kant, in diverse occasioni, a presentare Leibniz come un precursore della teoria della soggettività dello spazio. La seconda riguarda il motivo per cui Kant associa costantemente la monadologia alla teoria platonica delle idee, mostrando come, in entrambi i casi, Kant intenda criticare qualsiasi possibilità di un transito dal mondo sensibile a quello intelligibile. Infine, cercherò di mostrare che, dietro questa lettura deflazionista della monadologia, c’è anche un’implicita autocritica alle tesi che Kant stesso ha sostenuto nella Dissertatio del 1770.

Kant’s moral theory aims at highest good, and he believes that good will is the mote unconditioned kind of good in the world. According to Kant, human beings are continually subject to the reason’ demand, and they should try to cultivate their humanity following the universal moral laws. However, he doesn’t leave us with an ambiguity about the definition of these universal laws; proposing his categorical imperative, he leads us to the universal laws. He believes that we would go toward (...) unconditionality and the highest good following these rules. By the way, there are different interpretations of his categorical imperatives as well as some their extensions. There are two possible interpretations of the third formulation of categorical imperatives and its relation to the animal rights in general, and the vegetarians’ viewpoint in particular. Some people might believe that “being end in itself” is incompatible with vegetarianism. They will invoke some quotes from Kant’s work which support their views. In The Metaphysics of Morals, Kant Explicitly prescribes killing the animals and making use of them, and it can be served as strong evidence to the idea that Kant's moral theory is inconsistent with vegetarianism. However, I don’t think so. According to the second possible interpretation, I believe that Kant’s moral theory is incompatible with the interpretations proposed by those who think it is not compatible with vegetarianism. In the first part of this paper, I briefly explain the relationship of reason and nature in Kant’s moral theory. Then in the second part, I shall explain two concepts of “person” and “things” in his texts, and briefly, state the difference between rational being and non-rational being in his philosophy. Then. In the third part, I will explore some pieces by my Kantian opponent of vegetarianism, and I shall show that their interpretation is some kind of oversimplification. On the basis of some passages of Kant’s writings, using one mental experiment, and one counterexample, I hope to show that Kant is completely sympathetic to vegetarianism. (shrink)

In this paper, I outline Kant’s attempt to account for the category of relations, which is concomitant with his effort to prove that atomism cannot describe human experience. Kant’s journey from the First Critique to his last work the Opus Postumum is a struggle against atomistic versions of the world. In the last instance, it is a transit from I think to I act; and it is also recognition that to act can only be performed in a relational manner in (...) community with others. In order to substantiate his explanation of real forces in the world, Kant rethinks and extends his understanding of the subject from the subject as the unity of apperception to the self-positing subject living in the world with others. In order to defend ‘the being in the world’ who ‘has rights,’ I argue that we need to return to Kant’s general account of rights for all humans in the world. (shrink)

In order to secure the limits of the critical use of reason, and to succeed in the critique of speculative metaphysics, Immanuel Kant (1724–1804) had to present a full account of human cognitive experience. Perception in Kant’s Model of Experience is a detailed investigation of this aspect of Kant’s grand enterprise with a special focus: perception. The overarching goal is to understand this common phenomenon both in itself and as the key to understanding Kant’s views of experience. In the process, (...) the author argues against any such reading of Kant that puts too much emphasis on concepts and understanding in perception. This means that claims of the sort that intuitions cannot play their role without concepts, that sensibility cannot bring anything to cognition without being mediated through the functions of understanding, or that there is no such thing as concept-independent perception, are shown to be either plainly false or misleading at best. Together with the contemporary topics examined by the end of the book, the findings suggest how the role of conceptual thinking in human cognition has been exaggerated partly because of a misplaced interpretation of Kant, which not only makes perception far more intellectual in character than what was intended by Kant himself, but distorts Kant’s account of cognition by overlooking what there is at the heart of his critical philosophy: the revaluation of sensible cognition.

The distinction of things in themselves and appearances is an integral part of Kant’s transcendental idealism, yet it has often been met with rather significant hostility. Moreover, what surely has not contributed to the popularity of this Kantian doctrine is that there are, or at least there appear to be, two distinct models, detectable in Kant’s texts, to account for this distinction. Most commonly, these two models are called the “two aspect view” on the one hand and the “two world (...) view” on the other, but it is possible that these labels themselves invite misunderstandings and obscure rather than clarify what Kant had in mind with his distinction. In this paper, I shall first briefly discuss how these two models could be described and labelled in a more suitable manner, namely as the “one composite entity view” and the “two separate objects view”. Subsequently, I will enquire which of the models is pertinent for Kant’s solution to the 3rd antinomy. I will try to show that although the two models appear to be incompatible, it is at least plausible to read Kant as using both of them in this crucial text of his oeuvre. Moreover, Kant’s strategy in solving the freedom problem on the basis of an indirectly realist account of the divine intellect provides the clue to understanding how these seemingly incompatible models can co-exist without forcing Kant into maintaining contradictory claims.

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

Consider the claim that openmindedness is an epistemic virtue, the claim that true belief is epistemically valuable, and the claim that one epistemically ought to cleave to one’s evidence. These are examples of what I’ll call “ epistemic discourse.” In this paper I’ll propose and defend a view called “convention-relativism about epistemic discourse.” In particular, I’ll argue that convention-relativismis superior to its main rival, expressivism about epistemic discourse. Expressivism and conventionalism both jibe with anti-realism about epistemic normativity, which is motivated (...) by appeal to philosophical naturalism. Convention-relativism says that epistemic discourse describes how things stands relative to a conventional set of “ epistemic ” values; such discourse is akin to normative discourse relative to the conventional rules of a club. I defend conventionalism by appeal to a “reverse open question argument,” which says, pace expressivism, that epistemic discourse leaves the relevant normative questions open. (shrink)

Russellian panpsychism puts basic conscious properties at the bottom level and then grounds lowestlevel physical entities in them. This paper offers arguments against the view. The explanatory gap cuts both ways, making it as hard to get the physical out of consciousness as to get consciousness out of the physical. Russellian panpsychism can't explain how basic conscious properties yield high-level consciousness. Other non-physicalist views can evade the causal argument for physicalism at least as well as Russellian panpsychism. Simplicity and beauty (...) don't supply reasons for Russellian panpsychism.

The causal theory of properties is standardly combined with a realist's ontology of universals or tropes. In this paper, I consider an uncharted alternative – a nominalist causal theory of properties. I discuss advantages and disadvantages of the resulting theory of properties, and explore the Rylean understanding of causal powers that emerges.

'Structural realism' is a buzzword in the scientific realism debate. Various positions with diverse motivations fall under this label. A much advertised distinction is between epistemic and ontological forms of structuralism. This paper scrutinizes the alleged dichotomy between these two 'alternatives', and criticises the considerations that have been taken to motivate the ontic variety over the epistemic. I will argue that ontological structural realism is not called for within the traditional realism debate.

Rosenberg’s general argumentative strategy in favour of panpsychism is an extension of a traditional pattern. Although his argument is complex and intricate, I think a model that is historically significant and fundamentally similar to the position Rosenberg advances might help us understand the case for panpsychism. Thus I want to begin by considering a Leibnizian argument for panpsychism.

This paper proposes a critical examination of the wholism that Cartwright contemplates. The first part spells out the consequences of this position – notably our principled ignorance of nature as a whole. The second part considers that physical theory which is widely claimed to exhibit some sort of wholism, namely quantum physics. I sketch a wholistic model of quantum physics and compare this model to the wholism that Cartwright considers. The result is that – contrary to what Cartwright suggests – (...) we do not have to see ourselves as being ignorant of nature as such and our scientific view of nature can be quite systematic instead of being a patchwork. Finally, Cartwright’s wholism is confronted with confirmation wholism and semantic wholism. The result is again that these sorts of wholism speak against a patchwork view of our knowledge. (shrink)

So selbstverständlich es klingt, vom Geist, der Psyche oder auch der Seele eines Menschen zu reden, und so vertraut uns wissenschaftliche Disziplinen sind, die sich philosophisch oder empirisch damit beschäftigen, so schwer fällt es, ein einheitliches Merkmale dafür anzugeben, wann etwas ein psychisches Phänomen ist. Viele der potentiellen Merkmale decken eben nur einen Teil des Spektrums dessen ab, was wir gewöhnlich als psychisch bezeichnen würden, und sind damit bestenfalls hinreichende, aber sicher keine notwendigen Bedingungen des Psychischen. Im Mittelpunkt des folgenden (...) Artikels wird dagegen ein Merkmal stehen, von dem feststeht, daß es nicht hinreichend ist, von dem man aber vermuten kann, es sei zumindest notwendig: die Individualität psychischer Phänomene. Die Frage, mit der ich mich beschäftigen werde, ist, ob sich diese Vermutung mit Bezug auf eine Grnppe paradigmatisch psychischer Phänomene aufrecht erhalten läßt, die intentionalen Einstellungen.

Strawson’s case in favor of panpsychism is at heart an updated version of a venerable form of argument I’ll call the ‘intrinsic nature’ argument. It is an extremely interesting argument which deploys all sorts of high caliber metaphysical weaponry (despite the ‘down home’ appeals to common sense which Strawson frequently makes). The argument is also subtle and intricate. So let’s spend some time trying to articulate its general form.
