Virtual e Atual

(...)

what exactly does "virtualization" entail? According to Levy, "virtualization consists in an exponentiation of the entity under consideration. Virtualization is not a derealization (the transformation of a reality into a collection of possibles) but a change of identity, a displacement of the center of ontological gravity of the object considered". He then offers this suggestive, incisive characterization: "Virtualization fluidizes existing distinctions, augments the degrees of freedom involved, and hollows out a compelling vacuum"

Levy's work is particularly useful in the present context because it situates the virtual in the sense of media within a philosophical notion of the virtual taken from Gilles Deleuze (that in turn hearkens back to Bergson). Levy defines the virtual as "a kind of problematic complex...that accompanies a situation, event, object, or entity, and which invokes a process of resolution: actualization". Similarly, "The virtualities inherent in a being," he writes, "its problematic, the knot of tensions, constraints, and projects that animate it, the questions that move it forward, are an essential element of its determination". The virtual is not synonymous with the possible, because something that is possible is already fully constituted; it is waiting to be realized by being chosen. The virtual is an imbricated tangle, an enfolded multiplicity that must be resolved by being actualized, and it changes in the process. Thus, reverting to the electronic textuality discussion, a hypertext is not itself "virtual"; its lexia are rather a set of possible segments that can be traversed. The virtual dimension in a philosophical sense only comes into play when a mind enters the loop. Once that occurs, a text is "virtual" in that it presents an enveloped multiplicity that may be, through interpretation, actualized in any number of ways. This sense of virtuality is indifferent to media; a novel is as virtual as a hypertext. ]
