A concept is an abstraction that we use because it makes it easier to communicate. Although it seems that the concept of “concept” is easy to grasp, there are quite a few pitfalls with concepts.

Nevertheless, the unconsciousness finds it much more difficult to understand that concepts are abstractions and not real things.
