 Harlan furthermore declared, "The capacity to impart instruction to others is given by the Almighty for beneficent purposes and its use may not be forbidden or interfered with by Government—certainly not, unless such instruction is, in its nature, harmful to the public morals or imperils the public safety.The right to impart instruction, harmless in itself or beneficial to those who receive it, is a substantial right of property—especially, where the services are rendered for compensation.But even if such right be not strictly a property right, it is, beyond question, part of one's liberty as guaranteed against hostile state action by the Constitution of the United States."
