Similar to the quantifiers in first-order logic, “necessarily p” (□p) does not assume the range of quantification (the set of accessible possible worlds in Kripke semantics) to be non-empty, whereas “possibly p” (◇p) often implicitly assumes.

## What is modal philosophy?

Modal reasoning is central to human cognition, since it is pervasive both in philosophy and in every-day contexts. It involves investigating and evaluating claims about what is possible, impossible, essential, necessary, and contingent.

## What is a Kripke frame?

## What is modal in NLP?

Modal Operator is an NLP term that is used to identify specific words that enable us to identify our rules. You can spot these words in the language that you use and the language that other people use in order to identify rules that they may have formed for their lives. These rules may or may not be true.

## What is S4 modal logic?

## What is distortion in NLP?

Distortion in NLP is one of the three major processes (including Deletion and Generalisation) on which the Meta Model is based. Distortion occurs when something is mistaken for that which it is not, when things are incorrectly included in our Internal Representations.

## What is deletion in NLP?

Deletion in NLP is one of the three major processes (including Distortion and Generalisation) on which the Meta Model is based. Deletion occurs when we leave out a portion of our experience as we make our Internal Representations.
