New results on fuzzy concepts and concept lattices are presented. The issue of logical precision, a phenomenon thatalthough completely degenerate in two-valued logicnaturally arises in the context of fuzzy logic is studied. We present basic results regarding logical precision and concept lattices. Since, as far as we know, the phenomenon has not been discussed in literature so far, we briefly discuss its role in the general context of relational systems. We argue that logical precision should be considered as a possible way to treat the problem of information granularity from the logical point of view.
