So, no liberalism, no marxism, no capitalism, no Keynsian economics (probably no economics), no psychotherapy, no rock music ... the list is long for the things we can't reach consensus about.

What's left tends to be not so much "common sense" as "the stuff that supports the status quo, whatever it is", because human psychology tends to have a strong pro-status quo bias.

Couldn't we also say that stripped of their dogmas, these are all useful lenses? They're tools we have access to. Options. We've also collected a lot of information about when they might and might not be the appropriate device, or when they might even be harmful. The idea isn't to throw out history, nor to maintain the status quo. It's to solve individual problems using the best tools for the job, without getting emotional or activistic or wearing a t-shirt or waving a flag or joining the cult that revolves around the tool.

> to solve individual problems

Individual problems like:

* how do you distribute a resource that isn't evenly distributed on the planet?

* what, if anything, do you do about the variation in abilities across different people?

* what, if anything do you as various people in a community start to gain (and wield) more power than others?

* how do you address free riders?

There are so many more. The answers to these questions are not "right" and "wrong". They're not even of the form "this is best compromise we could come up with". The answers someone feels are best will be highly dependent on their values, which we know vary significantly. You can't just wish away the differences between what an eco-socialist would say about these things and an anarcho-capitalist. They are real differences, representing fundamentally different ideas about the nature of humanity, the role of government, the purpose of society and much more.

And as I said above, people have thought about these questions for centuries, and their answers generally fall into distinct groups (even if they are not all identical). We call these "ideologies".
