Whatever may be said about contemporary feminists’ evaluation of Descartes’ role in the history of feminism, Mary Astell herself believed that Descartes’ philosophy held tremendous promise for women. His urging all people to eschew the tyranny of custom and authority in order to uncover the knowledge that could be found in each one of our unsexed souls potentially offered women a great deal of intellectual and personal freedom and power. Certainly Astell often read Descartes in this way, and Astell herself has been interpreted as a feminist – indeed, as the first English feminist. But a close look at Astell’s and Descartes’ theories of reason, and the role of authority in knowledge formation as well as in their philosophies of education, show that there are subtle yet crucial divergences in their thought – divergences which force us to temper our evaluation of Astell as a feminist. My first task is to evaluate Astell’s views on custom and authority in knowledge formation and education by comparing her ideas with those of Descartes. While it is true that Astell seems to share Descartes’ wariness of custom and authority, a careful reading of her work shows that the wariness extends only as far as the tyranny of custom over individual intellectual development. It does not extend to a wariness about social and institutional customs and authority (including, perhaps most crucially, the institution of marriage as we see in her Reflection on Marriage). The reason for this is that Astell’s driving goal is to help women to come to know God’s plan for women – both in their roles as human and in their roles as women. According to Astell, while it is true that, as individuals, women must develop their rational capacities to the fullest in order to honor God and his plan for women as human, as members of social institutions, including the institution of marriage, women must subordinate themselves to men, including their husbands, in this case so as to honor God and his plan for women as women. Once we understand the theological underpinnings of her equivocal reaction to authority and custom, we can see that Astell may be considered a feminist in a very tempered way. My second task is to use these initial conclusions to re-read her proposal for single-sexed education that we find in A Serious Proposal to the Ladies. It is true that Astell encourages women to join single-sexed educational institutions for the unique and empowering friendships that women can develop in such institutions. Still, my argument continues, the development of such friendships is not entirely an end in itself. Rather, Astell encourages women to develop such friendships such that they can re-enter the broader world armed with the tools that will help them endure burdensome features of the lives that await them in the world, including their lives as subordinated wives –burdens that Astell does not, in principle, challenge.

According to Margaret Cavendish the entire natural world is essentially rational such that everything thinks in some way or another. In this paper, I examine why Cavendish would believe that the natural world is ubiquitously rational, arguing against the usual account, which holds that she does so in order to account for the orderly production of very complex phenomena (e.g. living beings) given the limits of the mechanical philosophy. Rather, I argue, she attributes ubiquitous rationality to the natural world in order to ground a theory of the ubiquitous freedom of nature, which in turn accounts for both the world's orderly and disorderly behavior.

The theories of pre-existence and epigenesis are typically taken to be opposing theories of generation in the seventeenth and eighteenth centuries. One can be a pre-existence theorist only if one does not espouse epigenesis and vice versa. It has also been recognized, however, that the line between pre-existence and epigenesis in the nineteenth century, at least, is considerably less sharp and clear than it was in earlier centuries. The debate (1759-1777) between Albrecht von Haller and Caspar Friedrich Wolff on their theories of generation is usually taken to be a debate between a pre-existence theorist and an epigeneticist, and the supposed fact that these two theories of generation are mutually exclusive explains (so the story goes) the divide between Haller and Wolff. However, it’s not clear that Haller endorsed an especially robust form of pre-existence, and nor is it clear that Wolff’s theory of generation -- once he considered it carefully -- is clear epigenetic. Rather, Haller’s theory of generation is marked by traces of epigensis and Wolff’s theory has elements of pre-existence theory. This is not to say that their theories of generation are basically the same, but the debate between the two ought not to be framed in terms of pre-existence versus epigenesis. Their points of difference must be explained in some other way. In this way, their controversy bears characteristics of similar disputes over generation in the nineteenth century more than it resembles those in the seventeenth century. In this paper, I argue that (a) Haller’s and Wolff’s theories both blend elements from pre-existence and epigenesis; (b) but there are still deeply-rooted differences between the two generation theories; (c) one source of these differences is that Haller and Wolff have divergent conceptions of what an adequate explanation is; (d) we can see that they have different conceptions of what constitutes an adequate explanation by paying heed to their evaluations of Descartes’ epistemology and methodology in his theory of generation (such as it is); and (e) this shows that one of the main differences between Haller’s generation theory and that of Wolff is the degree to which each thinks we need to (and indeed can) explain the nature of the causes -- both efficient and final -- at play during the formation of organic beings.

In this paper, I argue that Margaret Cavendish’s account of freedom, and the role of education in freedom, is better able to account for the specifics of women’s lives than are Thomas Hobbes’ accounts of these topics. The differences between the two is grounded in their differing conceptions of the metaphysics of human nature, though the full richness of Cavendish’s approach to women, their minds and their freedom can be appreciated only if we take account of her plays, accepting them as philosophical texts alongside her more standard philosophical treatises.

This paper has two parts: In the first part, I give a general survey of the various reasons 17th and 18th century life scientists and metaphysicians endorsed the theory of pre-existence according to which God created all living beings at the creation of the universe, and no living beings are ever naturally generated anew. These reasons generally fall into three categories. The first category is theological. For example, many had the desire to account for how all humans are stained by original sin (we were all there). As another example of a theological motivation, some take the organism as an obvious starting point for a teleological argument for God’s existence, and this staring point is sometimes developed into a full-blown theory of pre-existence. The second category could be thought of as non-theological metaphysical, and paramount here is the desire to deal with the metaphysical problem of individuation. So, for example, Leibniz embraces a version of hylomorphism in order to overcome difficulties with Descartes’ theory of material substance, including the difficulty of how to account for enduring material individuals, and Leibniz’s hylomorphism is closely linked with his embrace of pre-existence. The third category might be termed “biological”, and one example of such a concern is how to explain the organic unity of living beings where the whole seems to ontologically precede the parts. This is frequently translated into a temporal priority of whole to parts, and thus pre-existence is posited. Of course, many natural philosophers of the early modern period embrace pre-existence for more than one reason, but in general, these are the three classes of motivations one might have for embracing the theory. In the second part of the paper I examine in detail one argument that appears in the work of Malebranche. On the face of it, this argument seems to be a biological one, specifically the biological or organic holism argument mentioned above. But upon closer examination, I shall argue, Malebranche’s reasons for endorsing pre-existence bring together several of the arguments discussed in the first part of the paper. I conclude with some considerations about what we can learn about Malebranche as a natural philosopher from his motivations for holding the pre-existence doctrine of generation.

Between 1653 and 1655 Margaret Cavendish makes a radical transition in her theory of matter, rejecting her earlier atomism in favour of an infinitely-extended and infinitely-divisible material plenum, with matter being ubiquitously self-moving, sensing, and rational. It is unclear, however, if Cavendish can actually dispense of atomism. One of her arguments against atomism, for example, depends upon the created world being harmonious and orderly, a premise Cavendish herself repeatedly undermines by noting nature’s many disorders. I argue that her supposed difficulties with atomism expose a deeper tension in her work between two fundamental metaphysical commitments each of which has substantial philosophical support: her monist theory of the material world (which maintains that there exists just one natural substance which is the single principal cause) and her occasional theory of causation (which requires multiple finite principal causes in nature -- causes that might be considered individual substances). Her monism undermines atomism while her theory of occasional cause seems to rest on a conception of nature that would be especially friendly to atomism. I argue further that we can solve this tension within a Cavendishian framework in such a way as to preserve her theory of causation and her monism, but that this solution depends upon our taking her monism in a particular (and weak) form. I finally note that we can best make sense of her unique and interesting form of monism by acknowledging her social-political motivations in addition to her motivations in natural philosophy.
