Interpretations at any level are selective processes, and conscious selection is grounded in natural selection.
The problem is that natural selection among variant types causes the population to lose variation as the superior type comes to characterize the species. That is, selection destroys the very population variation that is the basis for its operation.
— Lewontin (2001, 80)
This seeming paradox, which explains why the little life of an organism or ecosystem tends toward senescence, also explains why any reading or explication has the effect of aborting other possible readings, in effect preventing what may have been equally implicit from ever becoming explicit. In the same way, the growth and development of the child progressively aborts most of the mature individuals he might have become. You don’t get another chance at living this day. With a turning symbol, on the other hand, you can return to a replica of it and resurrect the meanings that you missed by meaning something else by it previously.
