Glittering generalities (also called glowing generalities) are emotionally appealing words so closely associated with highly-valued concepts and beliefs that they carry conviction without supporting information or reason. Such highly-valued concepts attract general approval and acclaim. Their appeal is to emotions such as love of country and home, and desire for peace, freedom, glory, and honor. They ask for approval without examination of the reason. They are typically used by politicians and propagandists.
A glittering generality has two qualities: it is vague; and it has positive connotations.
Words and phrases such as “common good”, “reform”, “courage”, “democracy”, “freedom”, “hope”, “patriotism”, “strength”, are terms with which people all over the world have powerful associations, and they may have trouble disagreeing with them. However, these words are highly abstract and ambiguous, and meaningful differences exist regarding what they actually mean or should mean in the real world.
