Entity
From FLWiki
An entity is an element of a Flying Logic document (displayed as a rectangle with round corners) that contains a brief textual statement (its title) about reality or possible reality. The title of an entity is always stated in the certain present tense, for example:
[edit] Correct
- The door is open.
[edit] Incorrect
- The door will be open. (Not present tense.)
- The door might be open. (Not certain.)
In addition to its title, each entity also has a class that specifies what kind of entity it is.
Entities also have an associated confidence value, that can be interpreted either as a fuzzy boolean (an opinion of "how true" the entity is) or as a probability (an opinion of "how likely to be true" the entity is.)
Entities are connected by edges in causal relationships.
