A fundamental way of granulation the outer world performed by humans is that by forming concepts. We present a formal model of concepts and conceptual structures called fuzzy concept lattices which is a natural formalization of the Port-Royal approach to concepts. Fuzzy concepts, i.e. the induced fuzzy granules, obey a complete hierarchy w.r.t, subconcept-superconcept relation. Attention is paid to similarity relations (similarity of objects, concepts and conceptual structures are distinguished) and to logical precision both of which represent a systematic way to control the granularity and reduce the complexity of the conceptual structure. Applications in conceptual data analysis and representation of conceptual knowledge are discussed.
