Definition of a concept
On this page, we define what a concept is.
A concept is made up of two entities
A concept is always made up of two entities:
Concepts with both a type and a referent
The concept is drawn like this:
where the type and the referent are separated by a colon. For example:
[Person: John] "There exists a person whose name is John"
Here, "Person" is the concept type, and "John" is the referent.
Concepts with only a typeIf the referent is blank, the concept is drawn like this:
[Bus] "There exists a bus"
The type can never be blank.
We now discuss concept types in a little more detail.
