In his famous monadological metaphysics, Leibniz distinguishes between simple monads, animal monads, and rational monads or minds. This tripartite metaphysical distinction is mirrored by his discrimination between cognitive performances these three types of monads are capable of. Simple monads perceive; animal monads additionally remember, sense, and mimic reasoning by associating mental images; rational monads, furthermore, think, reflect on and know themselves, know eternal truths, and reason logically. This essay will focus on Leibniz's account of the cognitive performances of minds and their relationship to those of animal monads. After Leibniz's notion of perception is introduced in section three, in section four the essay turns to his conception of sensation in animal monads. The following sections five to seven address the mental performances typical of minds and present Leibniz's conceptions of ideas, concepts, thoughts, apperception, sensation in rational monads, and conscientia. While at the beginning of the essay Leibniz's views get situated in the context of early modern philosophy of mind, especially as it relates to Descartes and the Aristotelian tradition, the essay concludes with a summary of the main innovations we find in his conception of cognition.

Wie ist es zu erklären, dass wir uns vermittels geistiger Akte auf Gegenstände beziehen können? Und wodurch sind uns geistige Akte bewusst? René Descartes und Gottfried Wilhelm Leibniz geben faszinierende Antworten auf diese beiden zentralen Fragen der Philosophie des Geistes. In dieser Studie werden die Konzeptionen beider Autoren im Detail analysiert, miteinander verglichen und mit heutigen Positionen in Beziehung gesetzt. Die Analysen zeigen, dass Descartes eine deflationäre Konzeption des Bewusstseins (conscientia) vertritt. Bewusstsein ist „nur“ ein Aspekt der Intentionalität, die das wesentliche Merkmal des cartesischen Geists ausmacht. Die Analysen zu Leibniz weisen nach, dass er im Vergleich zu Descartes eine weitaus komplexere und anspruchsvollere Konzeption des Geistes vertritt, die aus heutiger Sicht anschlussfähiger erscheint. Die herausragenden Merkmale seiner Position sind die strukturelle Auffassung der Intentionalität und die Unterscheidung zwischen zwei Formen von Bewusstsein (apperception und conscientia), die dem phänomenalen Bewusstsein und dem reflexiven Selbstbewusstsein entsprechen. Im Unterschied zu Descartes weist Leibniz auch nicht-rationalen Tieren Bewusstsein in Form der Apperzeption zu. Conscientia bleibt dagegen den rationalen Substanzen vorbehalten.

This companion to the philosophy of John McDowell is the first comprehensive critical introduction to his work in German. It presents the central topics of his thought from the 1970s to the present day, explores McDowell's original interpretations and appropriations of the thought of philosophers from Aristotle to Sellars, and discusses his work from the perspectives of other philosophical schools and traditions. The book contains articles by Christian Barth, Georg Bertram, Christoph Demmerling, Johannes Haag, Christoph Halbig, Jens Kertscher, David Lauer, Jasper Liptow, Jan Müller, Hannes Ole Matthiessen, Christof Rapp, Raphael van Riel, Jan Slaby, Titus Stahl, David Weberman, and Markus Wild.

This paper argues in favour of lingualism, i. e., the position according to which thought depends on language. The notion of thought at issue is the one we apply when we understand ourselves as full-blown thinking beings. The argument takes advantage of an idea put forward by Donald Davidson. A modified version of this idea is developed into a comprehensive line of thought, which consists of five steps. The argument from truth claims that the possession of the capacity of thought requires possession of a grasp of the contrast between objective truth and falsehood. The subsequent four part arguments show that we can only conceive of a subject as phylogenetically acquiring a grasp of this contrast, if we conceive of her as acquiring a natural language. The conclusion of this argument implies that attributions of thought to non-linguistic being in contemporary ethology and developmental psychology must be carefully interpreted. They must not be understood as attributions of states we attribute to ourselves when we understand ourselves as thinking beings in the full-blown sense. Instead, the former notions of thought must be understood as technical notions, which are analogues to our ordinary notion of thought

The main aim of this paper is to show that we can extract an elaborate account of phe- nomenal consciousness from Leibniz’s (1646-1716) writings. Against a prevalent view, which attributes a higher-order reflection account of phenomenal consciousness to Leibniz, it is argued that we should understand Leibniz as holding a first-order concep- tion of it. In this conception, the consciousness aspect of phenomenal consciousness is explained in terms of a specific type of attention. This type of attention, in turn, is accounted for in terms of cognitive appetites aiming at knowledge about a repre- sented object by means of initiating cognitive operations on representational content. Furthermore, against the view that Leibniz holds a reifying account, it is argued that Leibniz accepts an epistemic account of phenomenal character. According to this view, the phenomenal character of phenomenally conscious states rests on the con- fusing effect of imperfect acts of attention directed towards representational contents. Holding this view, Leibniz finds fruitful middle ground between contemporary stan- dard positions like higher-order theories, representationalist conceptions, and qualia accounts of phenomenal consciousness. His position possesses resources to meet sev- eral objections these standard accounts are confronted with.

For Descartes, consciousness is closely connected to the intellective perception of thought. This paper argues that the prevalent interpretations of Descartes's account of consciousness in terms of higher-order perception and self-representation fail. These interpretations mistakenly assume that Cartesian consciousness possesses the same theoretical structure in all cases. It is shown by a close analysis of relevant passages that for Descartes the consciousness of perceptions and the consciousness of volitions have different theoretical structures. From this analysis a more adequate picture of Cartesian consciousness is developed and, finally, compared with a recent reconstruction provided by Vili Lähteenmäki

The aim of the paper is to illuminate some core aspects of Leibniz’s conception of judgement and its place in his conception of the mind. In particular, the paper argues for three claims: First, the act of judgement is at the centre of Leibniz’s conception of the mind in that minds strive at actualising innate knowledge concerning derivative truths, where the actualising involves an act of judgement. Second, Leibniz does not hold a judgement account of predication, but a two-component account that distinguishes between predication and alethic evaluation. Third, Leibniz understands the act of affirmative judgement in terms of establishing active dispositions, i.e. strivings, to make reasons available for future reasoning that aims at answering whether-questions. Correspondingly, he understands the act of negative judgement in terms of establishing dispositions to ban propositions from future reasoning that aims at answering whether-questions. In the final analysis, the acts of affirmative as well as of negative judgement turn out to be acts of changing memory dispositions.

Does thought depend on language? Primarily as a consequence of the cognitive turn in empirical disciplines like psychology and ethology, many current empirical researchers and empirically minded philosophers tend to answer this question in the negative. This book rejects this mainstream view and develops a philosophical argument in favor of a universal dependence of language on thought. In doing so, it comprises insights of two primary representatives of 20 th century and contemporary philosophy, namely Donald Davidson and Robert Brandom. Barth offers an introduction to the debate concerning the language-dependence of thought and lays the methodological foundation for the subsequent argument in favor of a universal dependence of thought on language, presenting an account and defense of the transcendental method in reference to the writings of Peter F. Strawson. He then offers a transcendental argument in favor of a universal language-dependence of thought, beginning with a reevaluation of a basic idea for an argument originally presented by Donald Davidson. Later, two main objections to the conclusion of this transcendental argument are addressed and rejected using Robert Brandom’s inferentialist and normativist account of thought and language. In the course of doing so, the recent debate on Brandom’s work is addressed extensively, and main objections to Brandom’s work are presented and answered
