This shows that personality is a relatively stable system of personal consciousness. There is a famous saying that "the world is material and material is moving", and people are also part of the material world, from which it can be deduced that "personality is constantly changing". However, because personality is relatively stable, the change of personality is inevitably driven by internal and external factors.
-1, the theory of external changes
The sentence "Man is the product of the environment" shows that no matter the change of man's material form and mental state, it is always based on the change of the environment. Whenever the living environment of an individual changes, the protection consciousness of future generations will actively adapt to the new environment, which will lead to a series of changes from the subject consciousness to the behavior mode, and finally adapt to the new living environment and obtain a better quality of life;
-2, internal change theory
Man is a creature with self-realization requirements, that is, what kind of person he will eventually become in what way he lives. Once this goal in life is set, you will strive for it. Therefore, people will actively abandon some behaviors that are not conducive to their own development, cultivate and develop some personality and psychological characteristics that are conducive to personal development, which will lead to a series of behavioral changes from the inside out, and finally make themselves better survive and develop;
-3. Invariance theory
People who hold the same view are generally stubborn and conservative, emphasizing only the negative side of human nature. It is believed that there will be a peak in the development of human consciousness, and as long as it reaches this peak, it is difficult to change human consciousness. But this is not the case, because people's living environment is always changing, and people are rational and intelligent creatures, so they will be more comfortable to adapt to the environment. Based on this principle, the change of human nature is absolute, unchangeable and only relative. From a philosophical point of view, the change of human nature conforms to the laws of natural movement.
-(1), but the personality change is a subtle process, and it is not easy to detect if the observation period is short;
(2) The change of personality is a process from thought to behavior, which is not immediately noticeable;
(3) There are essential differences between purposeful self-led personality change and environmental passive personality change. Self-led personality change is a process of improving self-quality, and the result is the expansion of vision and the improvement of ability, which is more conducive to fighting for one's rights and realizing one's ideals; Changing one's personality by the environment is blindly and passively adapting to the environment, thus being forced to give up the pursuit of one's own ideals and future and become a tool for others to achieve their goals.
