Semantic implicatures are features for understanding the use of sentences. The status of this implementations of meaning is a quasi-logical relation as a "weak implication". They are determinated through types of lexical units and expressions in grammatical positions. But both are only necessary conditions for semantic implicatures. Further assumption for meaningful use of sentences are presupposed e.g. existence presuppositions, evidences, customs etc. So, the delimination to pragmatic (presuppositions) is indicated.

In their book 'Foundation of illocutionary logic' the authors attempt to formalize the theory of speech acts. In set theoretical terms they describe their basic notions of illocutionary forces and points, define new ’illocutionary' symbols and operations and formulate some axioms and postulates, which should explicitly describe their theory, but their creativity of introducing new functional symbols and connectives conjoint with an unsystematic representation opposes this purpose.

Enquiring the sources and the legitimacy of Derrida’s statement “Law {droit) is not justice” from his essay “Force of Law: The ‘Mystical Foundation of Authority’ ” (1990), the paper analyses the three notions of “justice”, “equity” and “concordantia” (in Cusanus). Part I explains historically how the difference between the limited and changing human laws and the eternal justice of God was gradually being perceived and acknowledged in Antiquity. Part II illustrates how the virtue of equity was called upon to compensate for the insufficiencies and contradictions of human laws, mainly by Aristotle. Part III explores the conditions how and argues for the possibility that the notion of “concordantia” as developed by Nicolaus Cusanus for the Council of Basle could work as a mediating principle of legislation among conflicting interests and thus provide for temporary justice by means of an equitable procedure of legislation.
