“Ideology, n. An imaginary relationship to a real situation.

In common usage, what the other person has, especially when systematically distorting the facts.

But it seems to us that an ideology is a necessary feature of cognition, and if anyone were to lack one, which we doubt, they would be badly disabled. There is a real situation, that can't be denied, but it is too big for any individual to know in full, and so we must create our understanding by way of an act of the imagination. So we all have an ideology, and this is a good thing. So much information pours into the mind, ranging from sensory experience to discursive and mediated inputs of all kinds, that some kind of personal organizing system is necessary to make sense of things in ways that allow one to decide and to act. Worldview, philosophy, religion, these are all synonyms for ideology as defined above; and so is science, although it's a different one, the special one, by way of its perpetual cross-checking with reality tests of all kinds, and its continuous sharpening of focus. That surely makes science central to a most interesting project, which is to invent, improve, and put to use an ideology that explains in a coherent and useful way as much of the blooming buzzing inrush of the world as possible. What one would hope for in an ideology is clarity and explanatory breadth, and power. We leave the proof of this as an exercise for the reader.”
