I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline (...) to provide a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

Even to begin discussing the ethics of animal experimentation we must locate our place in the “ethical three‐ring circus” of the debate among “human welfarists,” “animal rightists” and those in the “troubled middle.” A philosophy of “nature alive,” recognizing that some animals are more equal than others, can inform the troubled middle and ethically justify judicious animal research.

The paper addresses the journal Jahrbücher für speculative Philosophie, published between 1846 and 1848 in Darmstadt. The paper focuses on the forewords of the journal written by the sole editor Ludwig Noack (1819–1885). In these forewords, Noack elaborates the current situation of philosophy. He outlines his vision for the future philosophy. It would be meaningful not only for professional philosophers but also for the general audience. Moreover, it would be closely associated with other sciences. Noack’s vision was (...) inspired by August Cieszkowski’s (1814–1894) so-called “Philosophie der Tat” (the philosophy of action), which resonated with the entire generation of German Hegelians from the late 1830s. Noack realized his journal in co-operation with the “Philosophische Gesellschaft zu Berlin”, founded by Cieszkowski and Georg Wilhelm Friedrich Hegel’s (1770–1831) former student Carl Ludwig Michelet (1801–1893) in 1843.

Although ostensibly defending speculative philosophy, Reck is doubtful that any unprejudiced speculative philosophy can exist: "No matter how much a philosopher may strive for neutrality, his test for the true philosophy is always predicated on the assumptions that his conception of being presents being as it is and that the conceptions of being his rivals uphold are partial or false." In the pursuit of neutrality, Reck attempts a mere chronicle of the distinctive conceptions of being (...) which he feels have animated the various metaphysical traditions: "Realism holds that whatever is in any sense is real; idealism that mind and its content alone are real; materialism that matter and its patterns alone are real; and process philosophy that process and the factors in process are real." The historical development of each of the four types is presented in masterly fashion. This book truly stands head and shoulders over its nearest rival in the Metaphilosophical literature for the depth of historical comprehension, the brilliant but controlled use made of a wealth of scholarship. A graduate student reviewing for comprehensive exams could do worse than to use Reck’s book. Those systems motivated at least in part by the drive-to-synthesis are disqualified a priori of being viable alternatives, motivated by distinctive intuitions. Realism, further, is found to have an inherent difficulty: "The task for the realist is to explain how the different levels or kinds of being can be related in a hierarchically ordered cosmos. The task is nothing short of explicating the bond of being." When Leibniz tries to relate finite particulars through a "Supreme Monad," he is faulted for "veering dangerously" close to Monism. Sympathetic toward Realism, Reck suggests a modification of Leibniz’s theory: not a rendering of the relations between man and God less mechanical, but a reduction of the "first Monad" from being supreme to a finite particular, struggling, like us, to overcome the hindrances posed by his environment. Reck concedes that the cognitive use of speculative philosophy, even when it redefines its project as Metaphilosophy, may be "futile"; however, he underscores the aesthetic value of the various systems, as Santayana would, when we can "bracket" the question of existence or truth and simply contemplate these cultural masterpieces as pure "essences." "Happy are those students who can suspend their critical search for truth sufficiently to savor the aesthetic values the systems of philosophy contain!" Reck refrains from judging between rival theories because such a judgment is always delivered from a view of what one takes to exist; and the impulse to go beyond "essence" to "existence" is, as Santayana teaches, prompted by fear, pain, instinct, or necessity. Rather than being a disinterested wonder at what "is," this passion is an "irrational agency of animal faith." "Needless to add," writes Reck, "animal faith is no more trustworthy than God’s existence to guarantee the truth of knowledge." This view can raise problems for Reck’s "finite" god. The finite god he prefers is perhaps "strong" enough to provide enough interconnection between existing particulars to justify a "Metaphilosophical" science, if not a properly "Philosophical" one, in the traditional sense; Reck could point to his own successful Metaphilosophy as evidence that his "god" is at least this strong. But isn't even this finite god an existential belief which, as the basis for a criticism, compromises one’s neutrality and thus constitutes a flaw in one’s Metaphilosophical theory? Is it possible that a totally adequate Metaphilosophical theory, on Reck’s canons, could not save enough interconnection between particulars to justify even a Metaphilosophy, as well as a Philosophy?—P.

Regarding the state of contemporary metaphysics, as it has been said, “There’s something in the air.” My goal in this essay is to offer some brief reflections on the state of contemporary metaphysics, otherwise called contemporary “ speculative ” philosophy – the “something in the air” – that has resurfaced within the early part of the 21st century. In order to clarify the nature of the new metaphysics in question I proceed by isolating geographically and topically two main (...) tendencies of thought which appear to constitute it: namely continental realism and continental materialism. I argue that clarifying the nature of these tendencies better characterizes what metaphysics means today. With respect to the possible ambiguity of “continental realism” or “continental materialism ” in the 21st century, a consideration of “ speculative realism” seems necessary if only to position my analysis upon a specific conceptual map. From there I offer thoughts as to how contemporary continental realism and materialism may be said to be defined first and foremost by its engagement with a concept identified as “correlationism,” a central feature of the new metaphysics ’ rejection of the sort of philosophy that has come before it.

Through both an historical and philosophical analysis of the concept of possibility, we show how including both potentiality and actuality as part of the real is both compatible with experience and contributes to solving key problems of fundamental process and emergence. The book is organized into four main sections that incorporate our routes to potentiality: potentiality in modern science [history and philosophy; quantum physics and complexity]; Relational Realism [ontological interpretation of quantum physics; philosophy and logic]; Process Physics [ontological (...) interpretation of relativity theory; physics and philosophy]; on speculative philosophy and physics [limitations and approximations; process philosophy]. We conclude that certain fundamental problems in modern physics require complementary analyses of certain philosophical and metaphysical issues, and that such scholarship reveals intrinsic features and limits of determinism, potentiality and emergence that enable, among others, important progress on the quantum theory of measurement problem and new understandings of emergence.

This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals (...) to multiple realizability to undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)

Most of all, this book introduces readers to a genuine lover of wisdom, a philosopher who used ordinary English to address traditional problems of philosophy.

Speculative Philosophy, or Pure Metaphysic, stands at the present time in a very interesting position. There is perhaps some degree of slackening in the construction of elaborate systems, though, with the recent examples of McTaggart and Professor Alexander before us, this may be open to some question. But at least we probably realize, more fully than was possible in previous generations, the exact nature of the problems with which pure metaphysic is concerned. Its work has been more and (...) more clearly marked off from that of the empirical sciences, and from that of the mathematical sciences ; and its province can now be definitely confined to the general theory of knowledge and the light that is thrown by this upon the structure of reality. It is my object in this paper to indicate briefly the chief problems that appear to fall within its scope and the chief directions in which we may look for light upon them. It is well to admit, however, that metaphysical problems are difficult, and that any statements that are made about them, unless expressed in language of a somewhat technical character, are very liable to be misunderstood. I must try to avoid both the Scylla of obscurity and the Charybdis of superficiality. (shrink)

In this paper I will offer a survey of Quentin Meillassoux’s thought, focusing on what I identify as the central node of his thought, the link between mathematics and contingency. I will then proceed to question the compatibility of his principle of radical contingency with the philosophy—and the practice—of science, and I will propose a possible solution to this problem by pushing Meillassoux along the Pythagorean path. Finally, I will argue that 1) his project of evacuating metaphysical necessity via (...) a mathematization of reality can be read on a continuum with the critiques of metaphysics of presence (and with the special status assigned to mathematical formalism) operated by Jacques Derrida and Alain Badiou; and 2) his philosophy can be understood as a philosophy of science only if we allow speculations aimed at subverting core metaphysical conceptual structures to have a bearing upon empirically-based scientific practice.

SummaryDogmatic debates in early Christianity shaped philosophical discourse just as Greek philosophy offered the conceptual tools to engage and, accordingly to crystalize early Christian practice, into a formal system of belief. Thus, in the recently-published The Rise of Christian Theology and the End of Ancient Metaphysics, Johannes Zachhuber notes that “Patristic thought as a whole can be identified as a Christian philosophy.” Following suit – though not without nuance – this paper suggests treating Patristic scriptural exegesis as an (...) exercise of speculative philosophy, as evidenced in Augustine’s interpretation of the figure of the cross at Eph 3.18, where the cross progressively becomes a simple yet compelling paradigm of divine manifestation. This paradigm can be framed according to Augustine’s mature articulation of the ‘ontological principle’ of manifestation in s. 165: “From the depth which you cannot see rises everything that you can see.” By engaging in scriptural exegesis, within a gestalt where Wisdom, sacred and profane alike, merge in the incarnate God manifest in Christ, Augustine articulates unprecedented philosophical principles.

I respond to the commentaries on 'Grace de Laguna's Analytic and Speculative Philosophy' offered by Peter Olen [2023], Trevor Pearce, Anthony Fisher, Marguerite La Caze and Frederique Janssen-Lauret. In doing so, I bring out some of the value of de Laguna’s perspectivism and of her treatment of modality. I also further clarify how she departs from pragmatism and from analytic philosophy, and how she relates to continental philosophy.

This paper contributes to explaining the rise of logical empiricism in mid-twentieth century (North) America and to a better understanding of American philosophy of science before the dominance of logical empiricism. We show that, contrary to a number of existing histories, philosophy of science was already a distinct subfield of philosophy, one with its own approaches and issues, even before logical empiricists arrived in America. It was a form of speculative philosophy with a concern for (...) speculative metaphysics, normative issues relating to science and society and issues which later were associated with logical empiricist philosophy of science, issues such as confirmation, scientific explanation, reductionism and laws of nature. Further, philosophy of science was not primarily pragmatist in orientation. We also show, with the help of our historical characterization, that a recent account of the emergence of analytic philosophy applies to the rise of logical empiricism. It has been argued that the emergence of American analytic philosophy is partly explained by analytic philosophers’ use of key institutions, including of journals, to marginalize speculative philosophy and promote analytic philosophy. We argue that this use of institutions included the marginalization of speculative and value-laden philosophy of science and the promotion of logical empiricism. (shrink)

“All that we require, and which can only be given us by the present advance of the single sciences, is a chemistry of the moral, religious, aesthetic ideas and sentiments, as well as of those impulses which we experience in ourselves both in the great and in the small phases of cultural and societal intercourse, and even in solitude.” In this passage from the opening paragraph of Human, All Too Human, Nietzsche prepares the ground for the transvaluation of modern culture (...) by means of a call for a renewed and enlarged understanding of chemical science. The need is a response to the dulling of modern culture: whereas the classical world-view attempted in vain to overcome such opposites as truth and error, or life and death, by seeing them from the perspective of an immutable standpoint, the more recent historical method has merely tended to dilute them in some supposedly fundamental element. Why does chemistry provide the model for the forthcoming transvaluation? (shrink)
