With these general principles prevised, we may consider, briefly, the respective rights of the individual and of society. The rights of the individual may be summarized as follows: There must be freedom of movement, including the right to withdraw from the domain of the government, to migrate at will to other territories. Freedom of movement is a fundamental condition of personal liberty, but it is easy to see that it cannot be made an absolute right. Quarantine laws, for social protection, for example, may seriously inconvenience the individual, but be imperatively necessary for all that. There must be immunity from arrest, except for infringing others' rights, with compensation of some kind for improper arrest; respect of the privacy of domicile and correspondence; full liberty of dress, subject to decency; freedom of utterance, whether by speech or publication, subject only to the protection of others from insult, injury, or interference with their equal liberties, the individual being held responsible to society for the proper use of that right. Freedom of the individual in all that pertains to art, science, philosophy, and religion, and their teaching, or propaganda, is essential. The state can have nothing to do with these matters, they belong to the personal life alone.[186] Art, science, philosophy, and religion cannot be protected by any authority of the state, nor is such authority needed. Subject to the ultimate control of society, certainly, but normally free from collective authority and control, these may be regarded as imperative rights of the individual. Doubtless many Socialists, in common with many Individualists, would considerably extend the list. Some, for instance, would include the right to possess and bear arms for the defense of person and property. On the other hand, it might be objected with good show of reason by other Socialists that such a right must always be liable to abuses imperiling the peace of society, and that the same ends would be served more surely if individual armament were made impossible. Again, some Socialists, like some Individualists, would include in the category of private acts outside the sphere of law and social authority the union of the sexes. They would do away with legal intervention in marriage and make it and the parental relation exclusively a private concern. On the other hand, probably an overwhelming majority of Socialists would object. They would insist that the state must, in the interest of the children, and for its own self-preservation, assume certain responsibilities for, and exercise a certain control over, all marriages. They would have the state insist upon such conditions as mature age, freedom from dangerous diseases and physical defects. While believing that under Socialism marriage would no longer be subject to economic motives,--matrimonial markets for titles and fortunes no longer existing,--and that the maximum of personal
