The concept of virtuality has been with us a remarkably long time. It is a coherent and functional idea in Plato’s writing, where both ideas and simulacra exist in some state of virtuality. Instead of too closely identifying it with the invention of new technologies — as is the current obsession — we must realize that since there has bee writing (in the Derridean sense of trace — that is, as the very I precondition of culture itself), there has been some idea of the virtual. The text we read may be in real space, but to the extent that it is comprehensible to us, it also exists in a state of virtuality. We did not have to wait for the computer screen or the movie projector in order to enter virtual space; we have been living in its shadow more or less continually.
