There are so many ideas that explain how racism began. According to the theory of polygenesis, racism arises from the different treatment given to each race with the existence of stratification between people. Racism can be broadly defined as an attitude, belief, behavior, or institutional arrangement that favors one racial group over another (Farely, 1995). From this definition we can see that racism is not just a distinction related to skin color, but can be elaborated in a broader scope. Discrimination that assumes one race is better than another race and an environment that provides different treatment for each race can be defined as an implementation of racism. For example, the sharpest uneven boundaries between races occurred in the educational and economic opportunities, politics, health, and social mobility of people in the United States in the 1920s. Racism has definitely impacted human life, especially race who felt directly discriminated against and treated differently. in their environment. Even though they have fought for equal treatment and opportunities, especially during times of economic crisis, society doesn't even care and maintains stratification. This condition leads to a decrease in the self-esteem of the black race because they are forced to feel that they are in no way better than another race. Racism also has an impact related to psychological stress, for example different economic opportunities will lead to stressful conditions when people have difficulty finding work just because of their skin. Studies have shown that people of color will be the first to be fired and the last hired, and this fact shows the economic depression during that time. The unemployment rate for blacks is about four times higher than for whites. Evident unjust services...... middle of paper...... after Adam there existed on this earth men who did not receive their origin by natural generation from him, the first parent of all, or that Adam signifies some multiple progenitor type; in fact, it is not at all clear how such an opinion can be reconciled with what the sources of revealed truth and the acts of the Church's magisterium teach about original sin, which proceeds from a sin actually committed by a single Adam, and which is transmitted to everyone generation to generation, and exists in each as its own" (Humani Generis 37). From the above statement it is clear that Pope Pius XII rejects the idea of ​​polygenism. Because the Church believes that Adam is the first man to exist on this planet . earth After the original sin he committed, a sin that banished him and Eve from the Garden of Eden and made them mortal. Therefore polygenism is against the teaching of the church.
