What is "pure ideology"?

no, seriously. it's a drug. think about it.

>They are saying we are all losers, but the true losers are down there on Wall Street. They were bailed out by billions of our money. We are called socialists, but here there is already socialism — for the rich. They say we don’t respect private property. But in the 2008 financial crash-down more hard-earned private property was destroyed than if all of us here were to be destroying it night and day for weeks. They tell you we are dreamers; the true dreamers are those who think things can go on indefinitely the way they are.

People shouldn't have taken out risky mortgages if they knew they'd struggle to pay them back.

And yet borrowers weren't bailed out, were they?

By your logic, the banks shouldn't have made risky loans they knew they wouldn't be repaid.

Let the borrower fail, let the lender fail, right?

Pure ideology is like when you're so high on ideology you become delusion and think you're a King, it's kind of like being on coke, except instead of a drug it comes from ideology.

Honestly pure ideology is the best shit ever, I recommend it to everyone I meet. Then again most people get cut as fuck ideology that doesn't even make your face numb and probably has baking soda in it; what's the fun of that?

Banks should have been punished for their reckless lending.

I think other posters have defined Ideology fairly well, particularly Ideology is a system that shapes how you see the world. Ideology is the realization that there is no objective or neutral position from which you can observe society.

Ideologies are philosophies, religions, scientific systems, social norms, laws and regulations, the commands of others, etc. They can be conscious or unconscious, and are often both.

But if your question is what is PURE ideology, Zizek tends to use the adjective Pure to describe a situation in which an ideological system is exerting a lot of influence, without the subject realizing it. Pure Ideology is Colonialism, or Absolute Monarchy, systems which never comprehended their own short comings, and took their perspective as entirely natural and obvious, as if there were no other way to perceive things.

In Zizek's sense of the term Ideology, there is no escaping ideology, everyone has it, but there are varying levels of awareness. To demonstrate this, he uses Donald Rumsfelds idea about Known Knowns, Known Unknowns, Unknown Unknowns and then Zizek's fourth term, Unknown Knowns, that completes the series. This fourth category, Unknown Knowns, the things we belief and act upon, without much consideration or awareness, is Pure Ideology or Unconscious Ideology.

The Big Other is not ideology. The Big Other is like an imaginary audience.

Ideology are the things we don't know we know, we take some fact or framework as granted without being aware of it. The Big Other is closer to virtue signalling or karma.
