The great principle, advanced by the learned and eloquent advocate of the plaintiff, is, that by the constitution and laws of Massachusetts, all persons without distinction of age or sex, birth or color, origin or condition, are equal before the law. This, as a broad general principle, such as ought to appear in a declaration of rights, is perfectly sound; it is not only expressed in terms, but pervades and animates the whole spirit of our constitution of free government. But, when this great principle comes to be applied to the actual and various conditions of persons in society, it will not warrant the assertion that men and women are legally clothed with the same civil and political powers, and that children and adults are legally to have the same functions and be subject to the same treatment, but only that the rights of all, as they are settled and regulated by law, are equally entitled to the paternal consideration and protection of the law, for their maintenance and security. What those rights are, to which individuals, in the infinite variety of circumstances by which they are surrounded in society, are entitled, must depend on the laws adapted to their respective relations and conditions. Conceding, therefore, in the fullest manner, that colored persons, the descendants of Africans, are entitled by law, in this commonwealth, to equal rights, constitutional and political, civil and social, the question then arises, whether the regulation in question, which provides separate schools for colored children, is a violation of any of these rights. The Massachusetts court faced the issue squarely, and concluded that separate schools did no violence to any civil right or privilege held by the colored children. The court’s inquiry was directed toward a single point: Was this a reasonable classification? Had the school trustees abused their responsibility? After great deliberation, the trustees had concluded that the good of both white and colored children would be promoted by separate primary schools. Said the court: “We can perceive no ground to doubt that this is the honest result of their experience and judgment.” It was urged that such separation tends to deepen and perpetuate the odious distinction of caste, founded in a deep-rooted prejudice in public opinion. Said the Massachusetts court: This prejudice, if it exists, is not created by law, and probably cannot be changed by law. Whether this distinction and prejudice, existing in the opinion and feelings of the community, would not be as effectually fostered by compelling colored and white children to associate together in the same schools, may well be doubted; at all events, it is a fair and proper question for the committee to consider and decide upon, having in view the best interests of both classes of children placed under their superintendence....
