Read the passage from the opinion of the court in Brown v. Board of Education, written by Justice Warren. We come then to the question presented: Does segregation of children in public schools solely on the basis of race, even though the physical facilities and other "tangible" factors may be equal, deprive the children of the minority group of equal educational opportunities? We believe that it does.

. . . To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely ever to be undone. . . .

Segregation of white and colored children in public schools has a detrimental effect upon the colored children. The impact is greater when it has the sanction of the law, for the policy of separating the races is usually interpreted as denoting the inferiority of the negro group. A sense of inferiority affects the motivation of a child to learn. Segregation with the sanction of law, therefore, has a tendency to ] the educational and mental development of negro children and to deprive them of some of the benefits they would receive in a racial[ly] integrated school system.

Whatever may have been the extent of psychological knowledge at the time of Plessy v. Ferguson, this finding is amply supported by modern authority. Any language in Plessy v. Ferguson contrary to this finding is rejected.

What reason does Warren give for believing that "separate but equal” does not give minority children equal educational opportunities?
