Freethought -or free thought- is a philosophical viewpoint which holds that positions regarding truth should be formed on the basis of logic, reason, and empiricism, rather than authority, tradition, revelation, or other dogma. The cognitive application of freethought is known as "freethinking", and practitioners of freethought are known as "freethinkers". The term first came into use in the 17th century to indicate people who inquired into the basis of traditional religious beliefs. (Wikipedia)
