It is an important basis of ontology to explain clearly what the subjective world contains. Frege and other Western philosophers were seriously wrong about concepts and the foundations of mathematics. The simulation is to mimic something with a fake product. People's knowledge about the world is also a kind of simulation. The content of knowledge is fake product relative to the object. The difference between people's knowledge and the object that is simulated can be made on purpose. The altered knowledge doesn't necessarily have real object corresponding to it. These thought games can bring about more value of knowledge and benefit in practice. The civilization and culture of human being mainly come from the innovative thought games. The logical construct of sentences describing something is a simulation of the thing or thought game. A symbol is a substance used to create an association in mind. Logical constructs have three advantages compared with real things: simple, useful, and stable. The concept is the logical construct produced after abstraction of things. Different degrees of abstraction can produce different degrees of concept. Abstract concepts of most disciplines retain more attributes, so they are not easy to analyze and study. The concepts of numbers and points, lines, planes and bodies are the results that retain few attributes after abstraction, which are simpler than concepts of other disciplines and easier to analyze and study.

A car is a concrete material, which can be simulated by words, images and other symbols to form a logical construct about the car. An event can also be simulated, that is to describe the event by words, images and other symbols. For example, to describe the process of accelerating and overtaking of a car, or describe an ancient story.

The simulation of objective laws is the scientific exposition of various theorems, axioms and principles. However, we cannot directly observe the objective laws, so we cannot directly simulate the objective laws. We can only observe events first, and then abstract the commonness of the events, we regard the abstract result as the simulation of the objective law.

All cars have wheels, which is a commonness. The description of this commonness is a logical construct. The commonness come from abstraction of individuals rather than simulation of objective commonness, which cannot be observed. In the process of abstracting events and individuals, there are many guesses and assumptions.

The relations of objective things includes time relation, space structure relation, same, similar, function relation and so on. Many simulations of relations also come from guess and assumption.

Materialists and Objective Idealists are wrong to think that the knowledge of objective laws and commonness comes from the simulation of them. We have never seen objective laws and commonness. We can only see individual things and events one by one. Since objective laws and commonness cannot be observed, they are never the criterion of truth. If we could see the objective law, then we can see whether our knowledge is right when we compare the objective law with our knowledge. But we cannot do that. The usefulness is the criterion of truth. Our knowledge of objective laws is considered to be true if it brings benefit when applied to practice.

3. Concepts are Logical Constructs

A concept is a symbol. When we see this symbol, we will have certain associations. The definition of a concept is the description of these association
