 Rozemond notes that after making this distinction Collins admits that all generical powers conform to the Homogeneity Principle. In her 2008 article, Rozemond claims that Locke did not accept that emergent properties are possible, because in his proof for the existence of God in Chapter 10 of Book IV of An Essay Concerning Human Understanding he invokes the Homogeneity Principle to show that an eternal and Intelligent Being could not be created by matter (Rozemond 2008:163). In fact, Clarke draws Collins’ attention to this very passage in the Essay (Clarke 1738 [1928: 837]; Clarke and Collins 2011: 170–171). If this were the only reference to the Homogeneity Principle in the Essay it would be difficult to see how Locke could also maintain that it would be possible for God to cause matter to think even if it were arranged in the right way. Clarke’s point to Collins is that on this basis he should give up the idea that thinking matter is possible. I take it that this is Rozemond’s point as well and she holds that in saying that the Homogeneity Principle applies to all generical powers, Collins is conceding the crucial point.
