“One cannot avoid a certain feeling of discomfort reading descriptions such as those of Lévy-Bruhl and the young Luria – descriptions that portray the concrete as “primitive”, as something to be replaced in the ascent to the abstract (this indeed has been a very general tendency in neurology and psychology for the past century). There should not be any sense of the concrete and the abstract as mutually exclusive, of the one being abandoned as one progresses to the other. On the contrary, it is precisely the richness of the concrete that gives power to the abstract. This is clearer if one is careful about defining it, and defines it in terms of “superordinate” and “subordinate”.
[…]
In abstracting, or generalizing, or theorizing, as thus understood, the concrete is never lost – quite the reverse. As it is seen from a broader and broader viewpoint, so it is seen to have ever-richer and unexpected connections; it holds together, it makes sense, as never before. As one gains in generality, so one gains in concreteness; thus the vision of the older Luria that science is “the ascent to the concrete.”
The beauty of language, and of Sign in particular, is like the beauty of theory in this way: that the concrete leads to the general, but it is through the general that one recaptures the concrete, intensified, transfigured. This regaining and renewal of the concrete, through the power of abstraction, is radiantly visible in a partly iconic language like Sign.”
