(Berkeley does say that the ideas of what “are called real things” differ from “those excited in the imagination” by “being less regular, vivid, and constant” (Berkeley 1710, Principles Part I, 33), but for him this difference does not challenge or undermine the claim that the esse of a physical object is its percipi.)

Although it has hitherto been argued that the _esse_ of things is in their _percipi_, this is now replaced by the more fundamental principle that the _esse_ of things is in their _percipere_ or _velle_.

The Approach to Philosophy Ralph Barton Perry 1916

Esse of the material is percipi: and the regularity of nature is no more than the order of ideas as produced in us by another spirit, namely, God.
