Why think that substances express their causes?

[Cross-posted from modsquad.] Leibniz thought (at least sometimes) that substances express God, because they express their causes. But why did he think that substances express their causes? In this post I briefly explore three ways in which we might try to understand his reasons for this. Version 1: expression and knowledge The late-1670s note “What is …

Leibniz on substances’ expression of God

[Cross-posted from modsquad.] Leibniz frequently uses the notion of expression. Expression is apparently a sort of representation relation. But what, according to Leibniz, has to happen for one thing to express another? Well, what often seems clear is the requirement that there be a regular relation between the expresser and the expressed. We might understand the debates …

Pasnau, Hobbes, and substance

[Cross-posted from http://philosophymodsquad.wordpress.com/2013/10/25/pasnau-hobbes-and-substance/.] Robert Pasnau, in his Metaphysical Themes 1274-1671, draws attention to two ways in which we find Hobbes talking about substance. One is found in De Corpore, among other texts. On this, “there is no room for metaphysical entities like the thin substance and its inhering accidents” (Pasnau 117). Indeed Hobbes wrote against Bramhall that …

What does Cavendish’s supernatural soul do?

[Cross-posted from http://philosophymodsquad.wordpress.com/2013/07/16/supernatural-soul-2/.%5D One of Margaret Cavendish’s longer discussions of the supernatural soul comes towards the end of part 2 of the Philosophical Letters [PL], where she discusses the work of Henry More. Unlike More, who believes in natural, extended, incorporeal spirits, we ought — Cavendish thinks — to distinguish between natural and supernatural souls. …

Cavendish and the divine, supernatural, immaterial soul

[Crossposted from http://philosophymodsquad.wordpress.com/2013/07/09/cavendish-and-the-supernatural-soul/.] Despite her materialism about nature, and her related view that the human mind is corporeal, Margaret Cavendish thought that human beings also have a divine and supernatural soul, which is not corporeal. There are plenty of questions one might ask about this, but for now I just want to ask when she thought …

Cavendish, strings, and sympathy

At one point, ‘sympathy’ seems to have been (largely?) a name for a physical phenomenon, and a certain sort of explanation of that phenomenon (see this earlier post on More and Mersenne). Over time, ‘sympathy’ seems to have become more exclusively used to describe a psychological phenomenon (e.g., Hume, Smith). I’m curious about how sympathy …

Toland and testimony

Thinking about a comment of Eric Schliesser’s about “Toland’s defense of book learning against the distrust of it by Moderns” reminded me of a feature of Toland’s Christianity not Mysterious [CNM] that I find a little puzzling. Early in Christianity not Mysterious Toland seems largely to be summarizing familiar Lockean views from the Essay. Thus …

Cudworth and basic obligations

In my previous post, I looked at Cudworth’s argument that good and evil (and other moral features) cannot arise from decision alone, for something good cannot simply be made good by decision, without being also given the underlying nature of a good thing. Of course, his opponents have some possible responses open to them. Not all obligations, …

Cudworth, tautologies, and natures

Prompted by Lewis’s mention of Cudworth, a post or two on Cudworth’s most famous argument. Book 1 of Cudworth’s Treatise Concerning Eternal and Immutable Morality [TEIM] contains a relatively short, and apparently free-standing, argument that morality cannot arise merely from decisions, either human or divine. Hobbes is among Cudworth’s targets, but so are Descartes and …

Burnett, on maps

I’ve been thinking about the correspondence of Thomas Burnett of Kemnay, particularly his correspondence with Leibniz (thus this earlier post and indeed this one).[1] Here I’d like to think a little bit about Burnett’s travels, and the geographical distribution of the correspondence. For now I’d like to focus on correspondence with Leibniz, and on the …
