1. Introduction It is generally assumed that, during his early pre-critical phase, Kant accepted a Leibnizian account of freedom according to which we are free to do otherwise than we do even though our actions are determined. This assumption is false. Far from endorsing such an account, Kant explicitly argues in the New Elucidation of the First Principle of Metaphysical Cognition that there is no relevant sense in which we can do otherwise than we do. Nevertheless, he is equally convinced (...) that we are free and responsible for our actions. And so he concludes that we can be responsible for what we do even if we could not have done otherwise. Little attention, however, has been paid to this argument. This is unfortunate, since a better understanding of this stage in Kant's theory of freedom would surely help us in understanding the later critical developments. This paper seeks to remedy this deficiency. (shrink)

Although a good deal has been written about Kant's conception of free will in recent years, there has been no serious attempt to examine in detail the development of his views on the topic. This book endeavours to remedy the situation by tracing Kant's thoughts on free will from his earliest discussions of it in the 1750s through to his last accounts in the 1790s. This developmental approach is of interest for at least two reasons. First, it shows that the (...) path that led Kant to view freedom as a transcendental power that is both radically distinct from and compatible with the causality of nature was a winding one. Second, it indicates that, despite the variety of views of free will that Kant held at various times, the concept occupied a central place in his thought, because it was the point of union between his theoretical and practical philosophy.

This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics: the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance.

In Spinoza’s metaphysics, we encounter many puzzling doctrines that appear to entangle metaphysical notions with cognitive, logical, and epistemic ones. According to him, a substance is that which can be conceived through itself and a mode is that which is conceived through another. Thus, metaphysical notions, substance and mode, are defined through a notion that is either cognitive or logical, being conceived through. He defines an attribute as that which an intellect perceives as constituting the essence of a substance. Intellectual (...) perception, something cognitive, is used to define an attribute, something metaphysical. And he claims that if something exists there is a reason why it exists and if something doesn’t exist there is also a reason why it doesn’t. Thus, a reason, something cognitive or epistemic, is necessary for existence or nonexistence. What are we to make of the intimate connections that Spinoza sees between metaphysical, cognitive, logical, and epistemic notions? Between being and reason? In this book, I argue for what might be called a realist interpretation: although Spinoza is confident that the order of being mirrors the order of reason, he believes that they are two orders, not one. There is inherence over and above conceptual dependence; there is causation in addition to causal explanation; the world has a nature that we can grasp and that our way of grasping it does not interpose an impenetrable conceptual veil between it and us.

This book presents a comprehensive examination of Gottfried Leibniz's views on the nature of agents and their actions. Julia Jorati offers a fresh look at controversial topics including Leibniz's doctrines of teleology, the causation of spontaneous changes within substances, divine concurrence, freedom, and contingency, and also discusses widely neglected issues such as his theories of moral responsibility, control, attributability, and compulsion. Rather than focusing exclusively on human agency, she explores the activities of non-rational substances and the differences between distinctive types (...) of actions, showing how the will, appetitions, and teleology are key to Leibniz's discussions of agency. Her book reveals that Leibniz has a nuanced and compelling philosophy of action which has relevance for present-day discussions of agency. It will be of interest to scholars and students of early modern philosophy as well as to metaphysicians and philosophers of action. (shrink)

This intellectual biography of Immanuel Kant's early years--from 1747 when his first book was published, to 1770 when his Critique of Pure Reason was about to be printed--makes an outstanding contribution to Kant scholarship. Schonfeld meticulously examines almost all of Kant's early works, summarizes their content, and exhibits their shortcomings and strengths. He places the early theories in their historical context and describes the scientific discoveries and philosophical innovations that distinguish Kant's pre-critical works. Schonfeld argues that these works were all (...) aspects of a single project carried out by Kant to reconcile metaphysical and scientific perspectives and combine them into a coherent model of nature.

Resumo O principal ponto de desacordo entre as filosofias emergentes e desenvolvidas no início do século XVIII na Alemanha é, indiscutivelmente, a alegação da possibilidade da metafísica a partir do princípio de razão suficiente. Este trabalho é dividido em duas partes. Inicialmente, apresenta-se o debate empreendido entre a tentativa de Wolff de justificação do princípio de razão suficiente – enquanto derivado do princípio de contradição – e a descrença de Crusius acerca de tal justificação. Defende-se que a posição desses filósofos (...) sobre a justificação do princípio de razão suficiente especifica as suas concepções de filosofia. Ao passo que Wolff argumenta que a filosofia, enquanto “ciência das coisas possíveis”, deve seguir o método da matemática, Crusius assegura que, ao dar conta da tarefa de considerar “as coisas realmente existentes”, a filosofia deve possuir o seu método próprio de investigação. Num segundo momento, considera-se o empreendimento kantiano de justificação do princípio de razão suficiente, de modo a dar conta das exigências tanto de Wolff como de Crusius. Argumenta-se que a busca kantiana de justificação do princípio na Nova dilucidatio de 1755 compreende os seguintes momentos: a garantia de uma equivalência lógica entre o princípio de contradição e o princípio de razão suficiente; o estabelecimento do princípio de razão suficiente como uma razão de existência do que existe de modo contingente. Palavras-chave : dedução, ontologia, metafísica alemã, princípio de contradição, princípio de razão suficienteThe fundamental point of disagreement among philosophies born and developed in Germany in the beginning of the XVIII century is, unquestionably, the defense of the possibility of metaphysics by means of the justification of the so called principle of sufficient reason. This paper is divided into two parts. Initially, the debate that ensued from Wolff’s attempt at a justification of the principle of sufficient reason as derived from the principle of contradiction in face of Crusius’ disbelief of such a justification is pointed out. It is sustained that the position of both philosophers concerning the justification of the principle of sufficient reason points to the specificity of their conception of philosophy. While Wolff argues that philosophy as a “science of possible things” should follow the method of mathematics, Crusius assures that, at holding the task of accounting for “truthfully existent beings”, philosophy must have its own method of investigation. Secondly, Kant’s undertaking at justifying the principle of sufficient reason accounting for the requirements of both Wolff and Crusius is taken into account. It is argued that Kant’s search for a justification in the 1755 Nova dilucidatio holds the following moments: the assurance of a logical equivalence between the principle of contradiction and the principle of sufficient reason; the establishment of the principle of sufficient reason as a reason of existence of that which exists in a contingent way. Keywords : deduction, ontology, German metaphysics, principle of contradiction, principle of sufficient reason. (shrink)

There is often said to be something peculiar about the history of modal theory up until the turn of the fourteenth century, when John Duns Scotus decisively reframed the issues. I wish to argue that this impression of dramatic discontinuity is almost entirely a misimpression. Premodern philosophers prescind from the wide-open modal space of all possible worlds because they seek to adapt their modal discourse to the explanatory and linguistic demands of their context.

The mature Leibniz frequently uses the phrase “moral necessity” in the context of discussing free choice. In this essay I provide a seventeenth century geneology of the phrase. I show that the doctrine of moral necessity was developed by scholastic philosophers who sought to retain a robust notion of freedom while purging bruteness from their systems. Two sorts of bruteness were special targets. The first is metaphysical bruteness, according to which contingent events or states of affairs occur without a sufficient (...) explanation. The second is semantic bruteness according to which a proposition can be true without a truth maker. Denying eithersort of bruteness was thought by some to raise problems for freedom. Defenders of moral necessity thought the notion solved these problems without having to invoke bruteness. (shrink)

The Prevolitional Condition: The subjunctive conditionals of human freedom known by God must have their truth value prior to any free decree of God, i.e., be known prevolitionally.

In the transcendental aesthetic of the Critique of Pure Reason, Kant claims that space and time are neither things in themselves nor properties of things in themselves but mere subjective forms of our sensible experience. Call this the Subjectivity Thesis. The striking conclusion follows an analysis of the representations of space and time. Kant argues that the two representations function as a priori conditions of experience, and are singular "intuitions" rather than general concepts. He also contends that the representations underwrite (...) some non-trivial a priori cognition of the objects of sensible experience. The Subjectivity Thesis is then presented as an immediate consequence: Space represents no property at all of any things in themselves nor any relation of them to each other. . . . For neither absolute nor relative determinations can be intuited prior to the existence of the things to which they pertain, thus [neither] can be intuited a priori. Time is not something which exists of itself, or which inheres in things as an objective determination. . . . [Were it] a determination or order inhering in things themselves, it could not precede the objects as their condition, and be known and intuited a priori by means of synthetic propositions. Kant's argument for the Subjectivity Thesis seems to have the following structure: * No absolute or relational features of things in themselves can be cognized a priori. (shrink)

Available for the first time in English, this critical translation draws from the original seven Latin editions and Georg Friedrich Meier's 18th-century German translation. Together with a historical and philosophical introduction, extensive glossaries and notes, the text is supported by translations of Kant's elucidations and notes, Eberhard's insertions in the 1783 German edition and texts from the writings of Meier and Wolff. For scholars of Kant, the German Enlightenment and the history of metaphysics, Alexander Baumgarten's Metaphysics is an essential, authoritative (...) resource to a significant philosophical text.

Kant actively struggles with the problem of how to conceive of God's creative action in relation to human freedom. He comes to the view that human freedom can only be protected if God withdraws in certain ways from the created world. The two pillars of Kant's mature philosophy - transcendental idealism and freedom - are in part shaped and motivated by Kant's need to provide a solution to his theological problem. The medieval and early modern theological tradition conceives of divine (...) action as unlike the action of any created being. When the creature acts, God directly causes this action, but without reducing the creature's freedom. Kant explicitly discusses and rejects this account of divine and human concursus. This rejection has significant and surprising ramifications for Kant's wider philosophy, explaining otherwise incomprehensible claims in his critical philosophy. Christopher J. Insole presents a definitive study in the history of ideas, engaging with a wide range of Kant's texts from 1749 until the early 1800s. Many of these texts have received little or no attention in Kant studies to date. Insole places Kant's thought in relation to numerous historical and traditional positions and illuminates these positions by a close engagement with recent debates in analytical philosophy and systematic theology. Kant is unrelentingly honest when grappling with the difficulty of relating divine and human freedom. This study, of Kant's theological struggle and legacy, goes to the heart of the problem in the modern reception of what the Christian tradition has affirmed about human freedom. As such, the book throws light on one of the defining fault-lines in modern theology and philosophy. (shrink)

This study gives the first English translation of Lectura I 39, a key text of the medieval theologian and philosopher John Duns Scotus (1266--1308), together with an introduction and a commentary. In the history of thought, Scotus is the first scholar to develop a consistent analysis of the basic Christian notions of contingency and freedom. This analysis can be found in his important early work, Lectura I 39, in which the question of whether God has knowledge of future contingents is (...) discussed. Reality is contingent, which means that reality in its factual shape could have been otherwise; God does not rule by determinism nor is He ruled by it -- nor is man, neither is their relationship. This fundamental insight made Christian thought turn away from the ancient conception that everything is (at bottom) necessary. For graduate students, philosophers and theologians. (shrink)

Samuel Clarke was by far the most gifted and influential Newtonian philosopher of his generation, and A Demonstration of the Being and Attributes of God, which constituted the 1704 Boyle Lectures, was one of the most important works of the first half of the eighteenth century, generating a great deal of controversy about the relation between space and God, the nature of divine necessary existence, the adequacy of the Cosmological Argument, agent causation, and the immateriality of the soul. Together with (...) the other texts presented in this edition, it also provides the best introduction to Clarke's philosophical views, which, in addition to their intrinsic interest, are historically important for the light they shed both on the philosophical positions within the Newtonian circle and on the exchange between Clarke and Leibniz, the most famous philosophical controversy of the eighteenth century.

Yitzhak Melamed here offers a new and systematic interpretation of the core of Spinoza's metaphysics. In the first part of the book, he proposes a new reading of the metaphysics of substance in Spinoza: he argues that for Spinoza modes both inhere in and are predicated of God. Using extensive textual evidence, he shows that Spinoza considered modes to be God's propria. He goes on to clarify Spinoza's understanding of infinity, mereological relations, infinite modes, and the flow of finite things (...) from God's essence. In the second part of the book, Melamed relies on this interpretation of the substance-mode relation and the nature of infinite modes and puts forward two interrelated theses about the structure of the attribute of Thought and its overarching role in Spinoza's metaphysics. First, he shows that Spinoza had not one, but two independent doctrines of parallelism. Then, in his final main thesis, Melamed argues that, for Spinoza, ideas have a multifaceted structure that allows one and the same idea to represent the infinitely many modes which are parallel to it in the infinitely many attributes. Thought turns out to be coextensive with the whole of nature. Spinoza cannot embrace an idealist reduction of Extension to Thought because of his commitment to the conceptual separation of the attributes. Yet, within Spinoza's metaphysics, Thought clearly has primacy over the other attributes insofar as it is the only attribute which is as elaborate, as complex, and, in some senses, as powerful as God.

This is a book about Kant's views on causality as understood in their proper historical context. Specifically, Eric Watkins argues that a grasp of Leibnizian and anti-Leibnizian thought in eighteenth-century Germany helps one to see how the critical Kant argued for causal principles that have both metaphysical and epistemological elements. On this reading Kant's model of causality does not consist of events, but rather of substances endowed with causal powers that are exercised according to their natures and circumstances. This innovative (...) conception of Kant's view of causality casts a light on Kant's philosophical beliefs in general, such as his account of temporality, his explanation of the reconciliation of freedom and determinism, and his response to the skeptical arguments of Hume.

In this collection of essays Béatrice Longuenesse considers the three aspects of Kant's philosophy, his epistemology and metaphysics of nature, his moral philosophy and his aesthetic theory, under one unifying standpoint: Kant's conception of our capacity to form judgements. She argues that the elements which make up our cognitive access to the world - what Kant calls the 'human point of view' - have an equally important role to play in our moral evaluations and our aesthetic judgements. Her discussion ranges (...) over Kant's account of our representations of space and time, his conception of the logical forms of judgements, sufficient reason, causality, community, God, freedom, morality, and beauty in nature and art. Her book will appeal to all who are interested in Kant and his thought. (shrink)

LEIBNIZ AND THE TWO SOPHIES is a critical edition of all of the philosophically important material from the correspondence between the philosopher Gottfried Wilhelm Leibniz (1646-1716) and his two royal patronesses, Electress Sophie of Hanover (1630-1714), and her daughter, Queen Sophie Charlotte of Prussia (1668-1705). In this correspondence, Leibniz expounds in a very accessible way his views on topics such as the nature and operation of the mind, innate knowledge, the afterlife, ethics, and human nature. The correspondence also contains the (...) only known philosophical writings by Sophie and Sophie Charlotte, and thus provides a valuable insight into their views and concerns, as well as throwing light on their characters. The texts are accompanied by a substantial introductory essay which sets the context for the correspondence and analyzes its main philosophical themes. (shrink)

In the Nova dilucidano Kant defines freedom as libertas spontaneitatis. Free acting is always determined acting. It differs from necessary acting by the fact that the determinating reasons are inherent in the acting subject. These reasons must not only be spontaneous but also rational ones. By this, Kant agrees in the main with the Leibnizian and Wolf fian conception of freedom. At the same time Kant refuses expressly the conception of freedom of Crusius. According to Crusius, free acting can not (...) be determined acting, because freedom is defined as unconditioned causality. This conception of freedom Kant postulates in the Critic of pure reason. The proof of the possibility of freedom given by Kant there differs however entirely from the proofs of freedom given by Crusius. According to Kant, it is not impossible to think freedom, because one and the same acting, one and the same phenomenon can be thought at the same time caused by laws of nature and by unconditioned causality, that is freedom, without any contradiction. This central argument of Kant's has an equivalent in the late Leibnizian theory of substance — not in the theory of freedom. Unconditioned causality as the causality of the vis activa primitiva and laws of nature as conditioned causality do not exclude each other at the same time in one and the same acting or phenomenon. Consequently already Leibniz postulates the Kantian thesis that the relation between unconditioned and conditioned causality is not a really disjunctive one. (shrink)
