Freedom of thought

Freedom of thought is the ability of an individual to hold or consider a fact, viewpoint, or thought. This process must happen independently of the viewpoints held by others. Every person tries to achieve cognitive proficiency by building knowledge, theories, and concepts. This proficiency allows people to assess their environment and find meaning. Developing new ideas often brings a sense of contentment to a person. It can also replace feelings of helplessness with hope for the future.

This freedom acts as a precursor and a progenitor to many other liberties. It is closely linked to freedom of religion, freedom of speech, and freedom of expression. While freedom of thought is often necessary for these other rights to exist, the reverse is not true. You do not need freedom of speech to possess freedom of thought. However, the existence of a right does not always guarantee its legal protection. In the Western world, most democratic constitutions work to protect these fundamental freedoms.

Many international legal documents protect the right to think freely. The United States Bill of Rights includes the First Amendment. This amendment states that laws cannot prohibit the free exercise of religion. In the 1937 case Palko v. Connecticut, Justice Benjamin Cardozo noted these ideas are vital. The Universal Declaration of Human Rights (UDHR) also protects this right. Article 18 of the UDHR protects freedom of thought, conscience, and religion. The United Nations' Human Rights Committee says these freedoms are protected unconditionally.

History shows many different views on the development of this concept. The Bible contains early ideas about this, such as the writings of Saul of Tarsus. In the 3rd century BC, the edicts of King Ashoka were called the first decrees respecting freedom of conscience. In the European tradition, Constantine I issued a decree of religious toleration in 313 AD. Many famous philosophers and theologians have championed this idea. These include thinkers like John Locke, Voltaire, and John Stuart Mill. Some, like Roger Williams, called it "soul liberty."

Despite its importance, leaders have often tried to suppress independent thought. Suppression can happen through censorship, arrests, or the burning of books. In Nazi Germany, book-burning campaigns were used to control ideas. In Cambodia, the government enforced radical anti-intellectualism under Pol Pot. The Soviet Union suppressed genetics research in favor of a theory called Lysenkoism. Other examples include the regimes of Augusto Pinochet in Chile and Francisco Franco in Spain. These actions are often used to discourage free thinking.

One notable figure in the history of free thought was Giordano Bruno. He was a theorist who wrote about an infinite universe. This topic was banned by the Catholic Church during his time. Bruno refused to recant his ideas to the Italian Inquisition. As a result, he was burned as a heretic in Rome. He is now remembered as a martyr for the cause of free thought.

Modern science and literature also explore how thought can be restricted. The Sapir-Whorf hypothesis suggests that thought is embedded in language. This means limiting words might actually limit the ability to think. George Orwell explored this in his novel 1984 through a language called Newspeak. Newspeak was designed to lack the capacity for metaphor or original ideas. Today, neuroimaging technology raises new concerns about privacy. The emerging fields of neuroethics and neuroprivacy study these digital threats to the mind.
