On other other hand, there are philosophers such as Quentin Meillassoux and Charles Hartshorne who state that the virtual does not "properly exist" - that there is a distinction to be made between the virtual and the concrete, and the concrete cannot said to "be" until *after* its actualization, whether possible or actual. While possibles and their corresponding actualizations are discreta, units or objects of the world, all of these individuals are susceptible to the more basic conditions of change, temporality. Surchaos, the eternal act of positive creative addition is no ground in the sense of any pre-individuated field of the real already containing fully formed individuals. Such a ground demands qualification.
Pragmatically, one "refers" to this power of pre-individuation though it is never a "thing" proper, as "nature" any more is some "thing" to refer to beyond a pragmatic concept within ordinary language. All individuals require this power for their actuality. Paul Weiss referred to this power as Dunamis, Meillassoux as Surchaos, Hartshorne, Peirce, and Whitehead as creativity - a kind of "inexistence" that makes *for* existence.
The question is not whether there *are* pre-individuated reals, nor whether any *individuated* real goes all the way down into the virtual realm (for example, it is "individuals all the way down" - a logical and ontological impossibility). It is rather a question of whether and how the *act* of individuation is a power deserving a significant ontological integrity. In essence, individuals are not interesting in metaphysical pluralism. It is what individuals *do* which is crucial, and even more crucially, what power they draw from, a power responsible for any doing, which seems to be the animating feature of the universe - thus deserving perhaps the character of "ultimate" or even "divine."
Any powers ontology must necessarily refer to this ground of creativity and positive creative addition, for it is what animates pre-individuated (possible) reals as well as their actual counter parts.
As a closing thought: Meinong's theory of possibles or Leibniz's particularism probably isn't the best way to go here. Insistence on how individuals are collected, aggregated, and then set into union through the *act* of "functors" (category theory) is much more helpful. Peirce, Whitehead, and even Hegel point the way to this kind of thinking. The below interview with Hartshorne draws out many of these contrasts. Note his example concerning Shakespeare.
