Studies of the Early Modern debate concerning absolute and relative space and motion often ignore the significance of the concept of true motion in this debate. Even philosophers who denied the existence of absolute space maintained that true motions could be distinguished from merely apparent ones. In this paper, I examine Berkeley's endorsement of this distinction and the problems it raises. First, Berkeley's endorsement raises a problem of consistency with his other philosophical commitments, namely his idealism. Second, Berkeley's endorsement raises (...) a problem of adequacy, namely whether Berkeley can provide an adequate account of what grounds the distinction between true and merely apparent motion. In this paper, I argue that sensitivity to Berkeley's distinction between what is true in the metaphysical, scientific, and vulgar domains can address both the consistency and the adequacy problems. I argue that Berkeley only accepts true motion in the scientific and vulgar domains, and not the metaphysical. There is thus no inconsistency between his endorsement of true motion in science and ordinary language, and his metaphysical idealism. Further, I suggest that sensitivity to these three domains shows that Berkeley possesses resources to give an adequate account of how true motions are discovered in natural science. (shrink)

This paper argues that a debate between Toland and Clarke is the intellectual context to help understand the motive behind the critic and the significance of Berkeley's response to the critic in PHK 60-66. These, in turn, are responding to Boyle's adaptation of a neglected design argument by Cicero. The paper shows that there is an intimate connection between these claims of natural science and a once famous design argument. In particular, that in the early modern period the connection between (...) the scientific revolution and a certain commitment to final causes, and god's design, is more than merely contingent. The details of PHK 60-66 support the idea that the critic is responding to concerns that by echoing features of Toland's argument Berkeley undermines the Newtonian edifice Clarke has constructed.

In this paper, I argue that Berkeley was a theological voluntarist in the Siris. I define theological voluntarism as the view that the divine will has conceptual priority over the intellect, implying serious ramifications for the modal status of the laws of nature. I identify four theses that are required to call Berkeley a full-blown voluntarist and show that we find all of them in the Siris: (i) God’s indifferent, arbitrary and free will enjoys conceptual priority over his intellectual functions; (...) (ii) nature is directly guided by, and its laws are grounded in, God’s will, meaning not only that physical things have no causal powers or essences which could ground the laws of nature; but also that (iii) God creates and maintains the physical world in accordance with law-like patterns of the phenomena arbitrarily established by particular divine volitions. As a consequence, (iv) whatever we can know about the metaphysically contingent laws of nature we know through induction from our limited experience. The Siris is particularly interesting from the perspective of voluntarism underlying these views, as, due to the alleged discontinuities with the early works and its Platonic tendencies in general, it seems to be the worst candidate for such an interpretation. In what follows, my principal aim is to show how wrong this appearance is, and that the voluntarist views Berkeley put forward in the Siris concerning the divine nature, the God-world relation, the laws of nature and the proper scientific methodology link it very naturally to his earlier considerations.
