The science of ideas.

A theory of the origin of ideas which derives them exclusively from sensation.

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.

"Ideology" means to favor one point of view above all others and to adhere to this point of view. The ideologue sees the world from a single point of view, can thus "explain" it and attempt to "change" it. The photographer, on the other hand, has numerous, equally legitimate points of view at his disposal. His goal is not to "explain" the world but to "record" it from ever different points of view. We should not be deceived, however, by the photographer's freedom from ideology. The ideology is still present, no longer in the photographer but hidden in the camera.
