  • noun A set or system of theories and beliefs held by an individual or group, especially about sociopolitical goals and methods to attain them; in common usage, ideology is such a set of beliefs so strongly held by their adherents as to cause them to ignore evidence against such beliefs, and thus fall into error -- in this sense it is viewed as a negative trait; contrasted to pragmatism, and distinct from idealism.
