Topic (Concept)

Topic is loosely defined as a subject of thought. Everything that has ever been mentioned inside the author’s mind is considered as a topic.

Classification

Topic is categorized into four fundamental categories:

1. People: All real human individual, e.g. the author’s friends, family, public figures, or the author himself.
2. Things: Everything beside people that can be perceived by physical senses. e.g. the author’s inventory, games, fictional characters, or this blog.
3. Concepts: Everything that cannot be perceived by physical senses, e.g. ideas, activities, or connections between multiple things or people. Topic itself is an example of a concept.
4. Events: Interaction between people, things, or concepts that is associated with a specific time.
