Freedom of speech is globally recognized as a human right to express information and ideas without censorship. It has been recognized throughout history in documents like the Universal Declaration of Human Rights. Freedom of speech includes the right to seek, receive, and impart information and ideas through any medium. While most modern societies uphold this right, there are still limitations around issues like sedition, defamation, and ridiculing general beliefs to balance this right with security, privacy, and social harmony concerns.
