Too Much Control or Too Little? • Not everyone in world has Internet access • Saudi Arabia: centralized control center • People’s Republic of China: ISPs sign“self-discipline” agreement • Germany: Forbids access to neo-Nazi sites • United States: Repeated efforts to limit access of minors to pornography

  19. Ethical Perspectives on Pornography • Pornography is immoral • Adult pornography is moral • Commentary

  20. Pornography Is Immoral • Kant • Loved person an object of sexual appetite • Sexual desire focuses on body, not complete person • All sexual gratification outside marriage wrong • Utilitarianism • Pornography reduces dignity of human life, harming everyone • Pornography increases crimes such as rape • Pornography reduces sympathy for rape victims • Pornography is like pollution that poisons the environment • Pornography industry diverts resources from more socially redeeming activities

  21. Adult Pornography Is Moral • Utilitarianism • Those who produce pornography make money • Consumers of pornography derive physical pleasure • Pornography is a harmless outlet for exploring sexual fantasies

  22. Commentary • Performing utilitarian calculus is difficult • How to deal with contradictory “facts” by “experts?” • How to quantify harms/benefits, such as harm done to people who find pornography offensive?

  23. Censorship • Direct censorship • Self-censorship • Challenges posed by the Internet • Ethical perspectives on censorship

  24. Direct Censorship • Government monopolization • Prepublication review • Licensing and registration

  25. Self-censorship • Most common form of censorship • Group decides for itself not to publish • Reasons • Avoid subsequent persecution • Maintain good relations with government officials (sources of information) • Ratings systems • Movies, TVs, CDs, video games • Not the Web

  26. Challenges Posed by the Internet • Many-to-many communication • Dynamic connections • Huge numbers of Web sites • Extends beyond national borders, laws • Can’t determine age of users

  27. Ethical Perspectives on Censorship • Kant opposed censorship • Enlightenment thinker • “Have courage to use your own reason” • Mill opposed censorship • No one is infallible • Any opinion may contain a kernel of truth • Truth revealed in class of ideas • Ideas resulting from discourse are more influential

  28. Mill’s Principle of Harm “The only ground on which intervention is justified is to prevent harm to others; the individual’s own good is not a sufficient condition.”

  29. Freedom of Expression • History • Freedom of expression not an absolute right • FCC v. Pacifica Foundation et al.

  30. History • De Scandalis Magnatum (England, 1275) • Court of Star Chamber • 18th century • No prior restraints on publication • People could be punished for sedition or libel • American states adopted bills of rights including freedom of expression • Freedom of expression in 1st amendment to U.S. Constitution

  31. 1st Amendment to U.S. Constitution Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

  32. Freedom of ExpressionNot an Absolute Right • 1st Amendment covers political and nonpolitical speech • Right to freedom of expression must be balanced against the public good • Various restrictions on freedom of expression exist

  33. FCC v. Pacifica Foundation et al. • George Carlin records “Filthy Words” • WBAI in New York airs “Filthy Words” (1973) • FCC issues declaratory order to Pacifica • Pacifica sues • U.S. Supreme Court ruled FCC did not violate 1st Amendment (5-4 decision) • Broadcast media “uniquely pervasive” • Broadcasting uniquely accessible to children

  34. Children and the Web • Web filters • Child Internet Protection Act • Ethical evaluations of CIPA

  35. Web Filters • Web filter: software that prevents display of certain Web pages • May be installed on an individual PC • ISP may provide service for customers • Methodologies • Maintain “black list” of objectionable sites • Examine content for objectionable words/phrases

  36. Child Internet Protection Act • Libraries receiving federal networking funds must filter pages containing obscenity or child pornography • U.S. Supreme Court ruled CIPA did not violate 1st Amendment guarantees(6-3 decision in June 2003)

  37. Ethical Evaluations of CIPA • Kantian evaluation: CIPA is wrong • Act utilitarian evaluation: depends on how benefits and harms are weighed • Social contract theory: freedom of conscience should be given precedence

  38. Breaking Trust on the Internet • Identity theft • Chat room predators • Ethical evaluations of police “sting” operations • False information

  39. Identity Theft • Identity theft: when a person uses another person’s electronic identity • Leading form: credit card fraud (more about this in Chapter 5) • Many victims are experienced computer users comfortable with typing credit card number online

  40. Chat Room Predators • Chat room: supports real-time discussions among many people connected to network • Instant messaging and chat rooms replacing telephone for many people • Some pedophiles meeting children through chat rooms • Police countering with “sting” operations

  42. False Information • Quality of Web-based information varies widely • Other media also have information of varying quality • The New York Times v. The National Enquirer • 60 Minutes v. Conspiracy Theory • Google attempts to reward quality • Ranking uses “voting” algorithm • If many links point to a page, Google search engine ranks that page higher
