logic variable

<programming> A variable in a logic programming language which is initially undefined ("unbound") but may get bound to a value or another logic variable during unification of the containing clause with the current goal. The value to which it is bound may contain other variables which may themselves be bound or unbound. For example, when unifying the clause sad(X) :- computer(X, ibmpc). with the goal sad(billgates). the variable X will become bound to the atom "billgates" yielding the new subgoal "computer(billgates, ibmpc)".

Two-variable logic

Two-variable logic with counting; Two-variable fragment

In mathematical logic and computer science, two-variable logic is the fragment of first-order logic where formulae can be written using only two different variables.L.

Term logic

In philosophy, term logic, also known as traditional logic, syllogistic logic or Aristotelian logic, is a loose name for an approach to formal logic that began with Aristotle and was developed further in ancient history mostly by his followers, the Peripatetics. It was revived after the third century CE by Porphyry's Isagoge.

Term logic revived in medieval times, first in Islamic logic by Alpharabius in the tenth century, and later in Christian Europe in the twelfth century with the advent of new logic, remaining dominant until the advent of predicate logic in the late nineteenth century.

However, even if eclipsed by newer logical systems, term logic still plays a significant role in the study of logic. Rather than radically breaking with term logic, modern logics typically expand it.
