"The right of freedom of speech and press has broad scope. The authors of the First Amendment knew that novel and unconventional ideas might disturb the complacent, but they chose to encourage a freedom which they believed essential if vigorous enlightenment was ever to triumph over slothful ignorance. This freedom embraces the right to distribute literature, Lovell v. Griffin, 303 U. S. 444, 303 U. S. 452, and necessarily protects the right to receive it. The privilege may not be withdrawn even if it creates the minor nuisance for a community of cleaning litter from its streets. Schneider v. State, 308 U. S. 147, 308 U. S. 162. Yet the peace, good order, and comfort of the community may imperatively require regulation of the time, place and manner of distribution. Cantwell v. Connecticut, 310 U. S. 296, 310 U. S. 304. No one supposes, for example, that a city need permit a man with a communicable disease to distribute leaflets on the street or to homes, or that the First Amendment prohibits a state from preventing the distribution of leaflets in a church against the will of the church authorities."
