On the one hand, it is the extinction of conscience, on the other hand, it is the victim of compatriots, and even the death of life. It is the loss of conscience of some people that contributes to the death of life. This is a sad and terrible thing. Some people's lack of conscience has profound historical and social roots. First of all, for a period of time, conscience was criticized as the theory of human nature together with humanity, humanity and even compassion, which made some people afraid to talk about conscience and so on, resulting in some young people missing classes in conscience education, thus not knowing what conscience is. Secondly, the wave of market economy washed away the encirclement and suppression of short politics, and money showed its unique magic and occupied a dominant position. In addition, the weakening and weakness of emotional civilization construction and ideological and moral education have led to the proliferation of "everything is about money", money worship and extreme individualism, which has led to the distortion of some people's values. In addition, the inheritance of the essence of traditional civilization has been destroyed, "money makes the mare go", the role of money has been infinitely exaggerated, and the conscience unrelated to money has been diluted, even forgotten and buried. There is a poem that says, "The clouds in Mo Tao cover your eyes". It is a "cloud" composed of colorful banknotes that covers some people's eyes, and it is the copper smell that defiles some people's souls. Therefore, in family, interpersonal relationship and social life, conscience has lost its due position and weight, and even is seriously absent. Come back, conscience! As an individual, you can't live without conscience; As a social group, we can't live without conscience. "Have no conscience? ! "It is not only the old people's questioning and censuring of unfilial children, or the victims' questioning and censuring of black-hearted people, but also the torture and lashing of all those who lack conscience, and it is also the call and cry for the return of conscience in our social life. Where does conscience come from? Mencius said: "People who have the ability but don't learn will have good ability. Those who know without learning have a conscience. " Another cloud says, "Everyone has compassion." This can be said to be the most authoritative interpretation of conscience. In fact, according to the materialist point of view, conscience is acquired, that is, the product of social environment. Therefore, conscience needs to be cultivated and instilled, and it can also be instilled, cultivated and trained. To cultivate conscience, we should cultivate the ability to distinguish right from wrong, good from evil from childhood. Conscience is one of the beautiful characters, and it is the basic project of moral and spiritual civilization construction and harmonious society. If a person doesn't even have a common conscience, can he handle family relations, interpersonal relations and social relations well? Talking about a harmonious society to such people is like casting pearls before swine. Therefore, we say that only on the solid foundation of conscience can we restore our moral standards and build a lofty building of a harmonious society.
