As a person, we should respect our parents, be kind to our children, be generous to our poor relatives and be polite to everyone.

Schopenhauer first described the essence of the law of sufficient reason. He said that this law had been abused by unreasonable people before him, which often made people fall into fallacy and confusion. In his view, the two basic properties of the law of sufficient reason are confused. One is the reason for judging, that is, judging is true, and the other is the reason for the change of objects, that is, the change of things, which are essentially different. In fact, Schopenhauer thinks that the law of sufficient reason has four different meanings, that is, all appearances can be explained from four levels, thus comparing these four meanings to "four roots".

In philosophy, Rousseau advocates that feeling is the source of knowledge and insists on the view of "deism"; Emphasize that human nature is good, and faith is higher than reason. Among us, who can tolerate the happiness and troubles in life best, I think it is the person who has received the best education. The money in our hands is a tool to keep freedom. Instilling truth into his mind is only to ensure that he will not fill his mind with fallacies. Decoration is also incompatible with virtue, because virtue is the strength and vitality of the soul. Bacon's famous saying:

Knowledge is power. The ideal of life is for the ideal life.

Books don't tell people their uses. The wisdom of using books is not in the book, but outside the book, all by observation.

Reading makes people perfect. Kant's "three criticisms" constitute his great philosophical system, which are: Critique of Pure Reason (178 1 year), Critique of Practical Reason (1788) and Critique of Judgment (1790). Living without an aim is like sailing without a compass.

Honesty is superior to all intelligence, because it is the basic condition of intelligence.
