The advantage to this approach is that it makes Lacan's travesty of the syntactical rules of the

predicate calculus even more apparent than his original notation.

It is not a simple matter to combine a large number of fragments, often with two or more free variables, into a single correct nth-order

predicate calculus query.

This information may be represented, in principle, in any number of ways, among which

The numerous proposed generalizations of Horn clauses will bring LP increasingly close to the original goal of programming in the full

predicate calculus.

Frege's

predicate calculus was regarded by its founder as offering a better representation of thought than that available in natural language, which on account of its ambiguity and reliance on context is an inappropriate medium for the representation of mathematical proof.

The completeness of the

predicate calculus links the syntactic property of formal provability with the conceptually quite different semantic property of logical truth.

Monadic calculus is certainly a constrained system compared to the full

predicate calculus.

In representing a proposition undergoing irtifa, the

predicate calculus is used.

To summarize it in a sentence, it is a frame-based language embedded in a more expressive

predicate calculus framework along with features for representing defaults, for reification (allowing one to talk about propositions in the KB) and for reflection (allowing one to talk about the act of working on some problem.

But our standard formal languages, for example, the

predicate calculus, feature only singular terms.

Some would argue that the limitation to

predicate calculus should be relaxed to encompass other more general forms of logic, for example, modal logics.
