Joel Katzav's survey of the philosophy of Grace Andrus de Laguna's philosophy covers a broad range of ideas, and I have selected three for further development and commentary: (1) the relationship between naturalism and analytic philosophy, (2) the relationship between classical and radical empiricism, and (3) the historical question of where to situate a view such as de Laguna's in the history, the present, and the future of philosophy. I suggest that the view belongs with a group I call the (...) ‘New Naturalists’, including Theodore de Laguna, Susanne Langer, Marjorie Grene, Michael Polanyi, and others who keep philosophy closer to developments in natural and social science than is typical for pragmatists, process philosophers, and analytic philosophers. This is a position somewhere between classical and radical empiricism, but which insists that reductionism is too limiting and unwise, even when restricted to being only a method. (shrink)

Grace de Laguna’s philosophical work was bold and original. She was also able to connect together seemingly disparate strands of the pragmatic, metaphysical and psychological research going on around her, as Joel Katzav shows in his paper. This commentary gives some historical background to her academic career in an attempt to explain how she could have been forgotten as a philosopher. Social and institutional factors led to her work not being recognized when she wrote and thus sinking into obscurity in (...) philosophical circles afterwards. Although her work was initially widely read, her research seems not to have had any continuing direct impact on later developments in philosophy. However, it is crucial to restore her thought to its rightful place in the history of our subject. (shrink)

In this paper I examine Grace A. de Laguna’s theory of universals in its historical context and in relation to contemporary debates in analytic metaphysics. I explain the central features of her theory, arguing that her theory should be classified as a form of immanent realism and as a powers ontology. I then show in what ways her theory affords a theory of modality in terms of potentialities and discuss some of its consequences along the way.

In this paper I build a case for considering the pioneering behaviourist philosopher Grace de Laguna as one of the grandmothers of analytic philosophy. I argue against the ‘Great Men’ narrative of analytic philosophy as composed of Moore, Russell, Wittgenstein and their followers, and in favour of a more inclusive ‘movement’ narrative of analytic philosophy as a broad and varied movement with an anti-idealist and naturalistic orientation aimed at fitting around novel development in the sciences, including Einsteinian physics and psychology. (...) I compare de Laguna’s prescient early views to Whitehead’s; both share an anti-idealist but also anti-atomist solution to the problem of perception, and both oppose the bifurcation of nature, with de Laguna expressing these views before Whitehead did. I conclude that while both opposed the narrower project of logical atomism, both count as ancestors of the wider analytic movement. (shrink)

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)

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.

Joel Katzav’s article describes and explains the realist perspectivist views of Grace de Laguna, showing the distinctiveness of her positions in a number of fields. My focus will be on her views of the self and persons, and how they are embedded in their communities, experience emotions, and develop morality. As Katzav outlines, de Laguna’s position can be characterized as a form of speculative philosophy that develops an ontology of modes of being. Katzav sees speculative philosophy and naturalism intertwining in (...) her work as de Laguna extends and criticizes science (the speculative aspect) as well as drawing on it (the naturalistic aspect). De Laguna’s project is to create a philosophical system that can be communicated to others. This system, according to Katzav, uses imagination, metaphor, and paradoxical formulations, such as ‘qualitative uniqueness’ to describe individuality, in a way that is common in continental philosophy. My commentary examines de Laguna’s views as they are set out by Katzav and suggests how his article opens up lines of philosophical inquiry concerning the self, community and morality. De Laguna’s views on these issues can also usefully be compared to those of Hannah Arendt to see how her articulation of these themes intersects with and differs from Arendt’s ideas. (shrink)

Grace de Laguna was a philosopher working in the first part of the twentieth century on analytic and speculative philosophy, as well as on the psychology and philosophy of language, especially the social function of language. Joel Katzav’s lead essay focuses mainly on the former part of her work, while my commentary focuses mostly on the latter. Katzav shows how her work played a role in the development of analytic philosophy, I try to show how her work played a role (...) in the development of pragmatic linguistics, whose development overlapped with some aspects of analytic philosophy. I situate it in the context of an emerging ‘pragmatic Weltanschauung’ that was embraced by many working in linguistics, philology, philosophy, psychology, anthropology and what would later be called linguistic pragmatics.

My response to Joel Katzav’s original article looks at potentially competing claims about perspectivism, psychology, and our understanding of concrete experience. De Laguna offers an early example of pluralism when conceiving of psychology, biology, physiology, and other sciences as essentially different perspectives abstracted from our experience of the world. Each science serves as a single perspective on experience, one that may shed light on our experience and behaviour from a particular standpoint, but does not represent ‘the real’ over and above (...) all perspectives. While remaining generally consistent throughout her career, I argue de Laguna’s exploration and endorsement of behaviourism—especially as it concerns emotion and affect—pushes her a bit closer to reductionism than originally intended. I explore this issue not by simply pointing out the potential inconsistency in her work, but by focusing on whether perspectivism makes sense in light of redundancies and complications between theoretical perspectives.

This commentary aims to place Grace de Laguna’s critique of pragmatism in its historical context. It examines her 1904 response to Henry Heath Bawden, her 1909 attack on John Dewey’s immediate empiricism, and her 1910 book Dogmatism and Evolution, focusing on the following question: Why did she describe her approach as an attempt to complete the pragmatists’ Darwinian revolution in logic?

1. With his lead article on Grace Mead (Andrus) de Laguna, Joel Katzav [2022a] has initiated a valuable addition to recent discussions of women in the history of philosophy. De Laguna was one of se...

In this paper, I develop what I call the Justification Encroachment (JE) Dilemma for Dormandy’s Evidentialism about Faith (EaF). The dilemma is this. If JE is true, then belief about objects of faith will be very difficult to justify, perhaps even impossible. If JE is false, then beliefs about objects of faith require no greater justification than any other belief, so that faith requires no more respect for evidence than anything else. After developing each horn, I consider very briefly how (...) a proponent of EaF might respond. (shrink)
