Years before the Court ever dealt directly with the subject of pornography, it wrestled with the limits of the First Amendment. Everyone conceded that the amendment's primary purpose had been to protect political speech, but the boundaries of political speech were hard to identify. Tunis Wortman had suggested as much in 1800. In A Treatise Concerning Political Inquiry and the Freedom of the Press, he had argued that unless people were allowed to "reflect and communicate their sentiments upon every topic," progress in all areas of knowledge would be threatened.
Thus, by 1950 the court had recognized that the First Amendment protected more than political speech narrowly defined. In addition, the court had acknowledged that there was no clear-cut line between the delivery of information and entertainment. It was ready to make the leap to pornography.
