Mary Shepherd (1777–1847) was a fierce and brilliant critic of Berkeley and Hume, who moreover offered strikingly original positive views about the nature of reality and our access to it which deserve much more attention (and credit, since she anticipates many prominent views) than they have received thus far. By way of illustration, I focus on Shepherd's 1824 Essay Upon the Relation of Cause and Effect, Controverting the Doctrine of Mr. Hume, Concerning the Nature of that Relation (ERCE). After a (...) brief setup, I canvas certain of her trenchant objections to Hume’s argumentation; I then present the positive core of her response to Hume, which consists in providing novel accounts of how reason alone or reason coupled with experience can justify, first, that every effect must have a cause, and second, that it is necessary that like causes produce like effects. Among other contributions here, Shepherd provides a distinctively metaphysical argument for the claim that nothing can begin to exist 'of itself' (going beyond an appeal to the Principle of Sufficient Reason, in particular), and leverages difference-making considerations to make the case that a single 'experimentum crucis' can justify causal belief (anticipating Mill's 'method of difference'). I close by highlighting salient features of Shepherd's metaphysics of causation, whereby causation is singularist and local (anticipating Ducasse and Anscombe) and involves synchronic interactions (anticipating Mill's and certain contemporary accounts), and according to which objects are essentially characterized by their causes and effects (anticipating contemporary causal or dispositional essentialist positions).

Shepherd’s philosophy centers on her rejection of Hume’s arguments against the demonstrability of causal principles. According to Shepherd, the causal maxim—everything that begins to exist must have a cause—is demonstratively true. She begins her first major philosophical work with a proof of this maxim. While scholars have complained that the proof seems blatantly circular, a closer look at Shepherd’s texts and their Lockean background dispels this worry. Shepherd’s premises are motivated not by the causal maxim or her theory of causation, (...) but by a metaphysics that distinguishes between substances and affections and by an empirical understanding of a ‘beginning of existence.’.

In this paper I argue for a novel interpretation of Shepherd’s notion of selfhood. In distinction to Deborah Boyle’s interpretation, I contend that Shepherd differentiates between the mind and the self. The latter, for Shepherd, is an effect arising from causal interactions between mind and body – specifically those interactions that give rise to our present stream of consciousness, our memories, and that can unite these two. Thus, the body plays a constitutive role in the formation of the self. The (...) upshot of this interpretation is that it can dissolve the problem of individuating mind that Boyle identifies. Briefly, the problem consists in Shepherd seemingly individuating minds in terms of their associated bodies and bodies in terms of the minds they are united with. My interpretation, however, allows to see that Shepherd neither wants nor needs to individuate the mind in isolation of the body and to read the passages, in which the problem seems to arise, as being about what makes living beings individual – with mind and body both playing a crucial role in this context.

Shepherd appears to endorse something like the following biconditonal regarding qualities and objects. □(An object, O, exists ↔ Some bundle of qualities, Q1, Q2, … Qn exists). There is a growing consensus in the secondary literature that she also takes the right side of this biconditional to ground the left side. I.e. Shepherd is a bundle theorist who takes an object to be nothing but a mass of qualities, or causal powers. I argue here that despite appearances, this interpretation reverses (...) Shepherd's actual view. I.e. I argue that for Shepherd qualities, or causal powers, are grounded in the intrinsic constitutions of objects. In the case of "external objects", these intrinsic constitutions are unknowable to us; in the case of "internal objects", we have direct knowledge of them. (shrink)

The aims of this paper are twofold. First, I offer a new insight into Shepherd’s theory of mind by demonstrating that she distinguishes a threefold ‘Variety of Intellect’, that is, three kinds of minds grouped according to their cognitive limitations. Following Shepherd, I call them (i) minds afflicted with idiocy, (ii) inferior understandings, and (iii) sound understandings. Second, I show how Shepherd’s distinction informs her theory of education. While Shepherd claims that her views serve to improve educational practices, she does (...) not explain how her threefold ‘Variety of intellect’ does so. I argue that Shepherd’s distinction contributes to her aim by providing pedagogues with a more comprehensive grasp of the various cognitive limitations of the people in their care. This allows the former to adjust their expectations and to provide need-oriented guidance. (shrink)

This paper explores the role that Mary Shepherd's (1777–1847) acceptance of the so-called imago-dei thesis plays for her account of the human mind. That is, it analyses Shepherd's commitment to the doctrine that humans are created in the image of God, (see Gen. 1, 26–7) parts of which Shepherd quotes in Essays on the Perception of an External Universe (EPEU), 157, and the ways it informs her understanding of the human mind. In particular, it demonstrates how this thesis informs her (...) understanding of the cognitive and moral capacities of the human mind. In other words, I argue that her commitment to this thesis explains why she believes that human beings are capable of reaching the “higher acquirement of intelligence” and the “completion of virtuous habits” (EPEU 381). Thus, this paper highlights the relevance of Shepherd's theological assumptions to (the ever-growing number of) scholars interested in her understanding of the mind. (shrink)

Shepherd defends an account of the universe founded on two causal principles: that effects necessarily have causes, and that like causes have like effects. Folding mind into the class of natural phenomena governed by these principles, Shepherd naturalizes the mind, but in doing so she sets herself the challenge of explaining how, within a deterministic universe, agents can be necessary causes of their own actions. With special attention to Shepherd’s resistance to materialism and to any reduction of the mental, the (...) paper argues that we can read Shepherd as leveraging her original theory of causation to develop a distinctive compatibilist view of the psychology of intention, one that makes agents the necessary causal sources of their own actions.
