  This extended abstract gives a brief outline of the connections between the
descriptions and variable concepts. Thus, the notion of a concept is extended
to include both the syntax and semantics features. The evaluation map in use is
parameterized by a kind of computational environment, the index, giving rise to
indexed concepts. The concepts are inhabited into language by the descriptions
from the higher order logic. In general the idea of object-as-functor should
assist the designer to outline a programming tool in conceptual shell style.
