1, definition

If we make a brief definition of history, I think it is most appropriate that history is a chronicle, which simply means "dealing with some real events that happened at a specific time and place". Please note that we don't include the word "specific person" in the definition here, just to remind you that the protagonist of history is not always us human beings.

2. Essence

The time when history happened may not be in ancient times, but it may also be yesterday. It cares about the past. Its essence is an oral story and knowledge of a special event. It not only existed in the past, but also experienced a series of changes in different times.

Second, scientific works.

1, definition

Now let's give a simple definition of science-it is a system that discovers laws or general principles and applies them to reality. It is a practical activity that combines subjective knowledge with objective reality, a bridge to the expected goal, and a link between reality and ideal.

2. Essence

Science is concerned with what may happen anytime and anywhere, not just what has happened like history. What it cares about is what causes all or most situations, how it happens, what are the inherent laws and hidden laws between them, and how we use them.

Third, philosophical works.

1, definition

Let's define philosophy simply and clearly-it is a system to study world outlook, values and outlook on life, including some basic issues, such as the nature of the universe, the general law of the evolution of everything in the universe, the position of people in the universe and so on.

2. Essence

It pursues universal truth, not specific events that happened in the past. No matter whether the past is modern or distant, what it emphasizes is generally related to our daily, routine and normal life experiences.
