Cognitive liberty then can be seen as an extension of or an "update" to the right to freedom of thought as it has been traditionally understood. Freedom of thought should now be understood to include the right to determine one's own mental state as well as the content of one's thoughts. However, some have instead argued that cognitive liberty is already an inherent part of the international human rights framework as the principle underlying the rights to freedom of thought, expression and religion. The freedom to think in whatever manner one chooses is a "necessary precondition to those guaranteed freedoms." Daniel Waterman and Casey William Hardison have argued that cognitive liberty is fundamental to Freedom of Thought because it encompasses the ability to have certain types of experiences, including the right to experience altered or non-ordinary states of consciousness. It has also been suggested that cognitive liberty can be seen to be a part of the inherent dignity of human beings as recognized by Article 1 of the UDHR.
