I have an idea, please advise me.

Your question is a question of conscious initiative.

Dialectical materialism holds that the world is objective and consciousness is an objective reflection. (This kind of reflection is right or wrong) But subjective consciousness can have a dynamic effect on the objective.

Consciousness reflects the right or wrong of objective things. For example, there is a picture in psychology, and the line segments are equal in length and width. If you put them in different positions, you will have visual errors and think that they are not the same length. And physically, if you put a cold sheet in warm water, you will feel hot. You think it is high temperature. These feelings are errors of contrast, and in consciousness, they are false projections.

The initiative of consciousness is to change things by turning consciousness into action. But all this must rely on objective actions or things. In short, you realize that you should study hard, and then study hard, and your grades will improve. The difference between idealism and materialism lies in whether this consciousness is primary or primary, or the objective process of your efforts is primary.

You said peace of mind and natural coolness, and "disappearing" said.

It is the initiative of consciousness.

Mentally, philosophically, when you are calm, you will feel cool.

1. If the temperature really drops, it's because your consciousness has changed the physiological blood of your brain or something (medical knowledge). This is the active role of consciousness, that is, after you realize the benefits of silence, your brain consciously relaxes and your body changes. The main test is physiological regulation, which is objective.

2. If the temperature doesn't really drop. It's just a feeling, then it's a wrong reflection of objectivity by consciousness.

In a word, I won't say that your mind moves, your physiology remains the same, and the temperature naturally drops.

Let's talk about disappearing.

Just because you forgot it doesn't mean it didn't happen. His existence is objective, but your subjective consciousness can remember him or forget him. Psychologically speaking, there are temporary forgetting and permanent forgetting. But your subjective consciousness does not determine his objective existence.

Finally, your forgetting process is objective, which means you can say, I forgot. You forget that this matter exists objectively. But this refers to the "forgetting process" itself. Not that thing. That thing exists objectively. These are two things.

For example, someone cut off his finger to prove subjective idealism.

Ask the teacher if the material comes first. Why did my consciousness decide his decision?

The teacher asked, do you feel pain?

The pain mentioned by the teacher here is objective, and your consciousness is the correct reflection of physiological changes.

And the students are talking about broken fingers. First of all, how can you break them without fingers? How can it be broken without a knife?

As for the consciousness of finger-breaking refutation, you wouldn't even have this idea without fingers. It is the dynamic role of consciousness and the behavior driven by consciousness. But the existence of fingers, tools and behaviors. The existence of pain is objective.

Generally speaking, there are three world views at present.

The main difference of this score is whether consciousness comes first or existence comes first. This is the origin of the world.

1. materialism 2. Idealism 3. Dualism (the combination of the two)

The following views are all Marxist philosophical views (because the world has not yet reached an agreement on this matter).

Materialism is not all scientific. Only historical dialectical materialism is scientific. It is the combination of natural view and historical view, and the unity of dialectical view and materialism.

What is unscientific is that these unifications are metaphysics, which can be divided into mechanical materialism (materialistic but less dialectical, such as carving a boat for a sword) and sophistry (dialectical but not materialistic).

2. Idealism is divided into subjective idealism and objective idealism.

Subjective idealism. It is relative to objective idealism. The main difference between the two is that the former thinks that everything exists in one's consciousness, feelings, ideas and experiences. Without personal consciousness, the world does not exist. The world depends on consciousness. Simply put, everything exists in the subjective spirit of the self. The latter regards this consciousness as an independent objectivity. An objective spirit, an absolute spirit, not personal. This absolute spirit is the origin of the world. Before the world appeared, the world had this spirit, such as religious belief.

3. Dualism

Think that the world is an objective combination of subjective courses. Both are equally important.
