Dogma, in its broadest sense, is any belief held definitively and without the possibility of reform. It may be in the form of an official system of principles or doctrines of a religion, such as Judaism, Roman Catholicism, Protestantism, or Islam, the positions of a philosopher or philosophical school, such as Stoicism, and political belief systems such as fascism, socialism, progressivism, liberalism, and conservatism.
In the pejorative sense, dogma refers to enforced decisions, such as those of aggressive political interests or authorities. More generally, it is applied to some strong belief that its adherents are not willing to discuss rationally. This attitude is named as a dogmatic one, or dogmatism, and is often used to refer to matters related to religion, though this pejorative sense strays far from the formal sense in which it is applied to religious belief. The pejorative sense is not limited to theistic attitudes alone and is often used with respect to political or philosophical dogmas.
