Interpreting this program in

propositional logic results in the set RF(P) of implications:

Let us show that we can conclude by using the

propositional logic that most people are unhappy.

Interestingly, two chapters--"The

propositional logic of the map" and "Threatened nature", use maps of Australia, unfortunately none from Australian sources, to illustrate the theme of the text.

The constants of

propositional logic contain also symbols, which are similar to the words of colloquial language: "and", "not", "or", "implies", "if and only if".

The difference between ordinary

propositional logic (PL), and the modal logic lies precisely with the concept of implications.

propositional logic by simply typed lambda-calculus is a significant part of interest of computer scientists.

the KB may contain statements about the world, perhaps in

propositional logic, predicate calculus, or some probabilistic structure (details below).

This includes automatically verifying that congruence closure, the theory of tree-embeddings, and the theory of nonstrict partial orderings are polynomial time decidable, that

propositional logic is in both co-NP and exponential time, and that the first-order theory of total orderings is in co-NP.

Kolmogorov seems more concerned with the interpretation of intuitionistic

propositional logic than with predicate logic; in fact, he gives only the propositional part of the formal axiom system ('calculus of problems').
