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. Natural souls are indeed extended, but are corporeal. Supernatural souls are something else entirely. But what are they? At times, Cavendish appears inclined to say that we simply cannot say what the supernatural soul is, only that it is. Thus PL 2.29 begins “Touching the State or Condition of the Supernatural and Divine Soul, both in, and after this life, I must crave your excuse that I can give no account of it”. And the remainder of that letter is partly occupied with listing topics that we should not meddle with, some of which are “Poetical Fancy”. Elsewhere she offers reasons why we cannot, at least naturally, know anything about this soul. But Cavendish is nevertheless sometimes more forthcoming about what the supernatural soul is like.
Some seemingly relevant passages — the passages featuring immaterial spirits in the Blazing World — contain her own fancies. These passages are certainly related to philosophical discussion, but we cannot simply read statements about Cavendish’s views about immaterial beings out of that fictional work. They would contradict things she clearly states elsewhere, in her more directly philosophical writings. For example, the immaterial spirits in the Blazing World talk about the “corporeal vehicles” that they require, but in PL 2.29 Cavendish lists the vehicles of souls as among the things to be taken “rather for Poetical Fictions, then Rational Probabilities; containing more Fancy, then Truth and Reason, whether they concern the divine or natural Soul”.
Leaving the fiction and fancy aside, however, Cavendish did venture some claims about what the supernatural soul is like.
