When I first read this it seemed like an excellent definition of Ideology. It still is, here it is below for your consideration. The quote is from: Above All Earthly Powers: Christ in a Postmodern World by David F. Wells. page 25.
‘What the Enlightenment ideology did was to provide an interpretive grid, an all-encompassing understanding, that was laid over the whole of life. This understanding was not much a worldview as an ideology. Ideologies, we might say, are worldviews with an attitude. The intent of every ideology is to control. With the passage of time and the desire to be triumphant, ideologies tend to become simplistic. They find acceptance because they tap into our need, the Canadian writer John Saul says, “to believe in single-stroke, cure all solutions” often presenting us with stark alternatives: “Accept the ideology or perish. Pay the debt or go bankrupt. Nationalize or starve. Privatize or go moribund. Kill inflation or lose all your money.”
Because they leave only one way out, they become coercive. At the same time, ideologies create a sense of inevitability about themselves. They produce passivity in people because what is inevitable cannot be resisted. And they breed intolerance of those who might be opposed to their understanding of life or might raise questions about it. It is these characteristics which help explain why it is so difficult to challenge an ideology once it has been socially ensconced. And yet this is exactly what has been happening with the Enlightenment ideology since the 1960’s.’
