A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms when serving in the militia … - John Paul Stevens

Great works of literature have frequently been produced by authors writing under assumed names. Despite readers' curiosity and the public's interest in identifying the creator of a work of art, an author generally is free to decide whether or not to disclose her true identity. The decision in favor of anonymity may be motivated by fear of economic or official retaliation, by concern about social ostracism, or merely by a desire to preserve as much of one's privacy as possible. Whatever the motivation may be, at least in the field of literary endeavor, the interest in having anonymous works enter the marketplace of ideas unquestionably outweighs any public interest in requiring disclosure as a condition of entry.

The ideas of liberty and equality have been an irresistible force in motivating leaders like Patrick Henry, Susan B. Anthony, and Abraham Lincoln, schoolteachers like Nathan Hale and Booker T. Washington, the Philippine Scouts who fought at Bataan, and the soldiers who scaled the bluff at Omaha Beach. If those ideas are worth fighting for -- and our history demonstrates that they are -- it cannot be true that the flag that uniquely symbolizes their power is not itself worthy of protection from unnecessary desecration.

Under our Constitution, anonymous pamphleteering is not a pernicious, fraudulent practice, but an honorable tradition of advocacy and of dissent. Anonymity is a shield from the tyranny of the majority. … It thus exemplifies the purpose behind the Bill of Rights, and of the First Amendment in particular: to protect unpopular individuals from retaliation--and their ideas from suppression--at the hand of an intolerant society. The right to remain anonymous may be abused when it shields fraudulent conduct. But political speech by its nature will sometimes have unpalatable consequences, and, in general, our society accords greater weight to the value of free speech than to the dangers of its misuse.
