I think Francis Bacon made the best point about this: knowledge—real knowledge—is about the ability to reliably recreate some effect. With something like the material characteristics of a metal, we can use the rigor of experiment to figure out how to create metals with desired characteristics. We subject the metal to varying levels of heat, pressure, etc. and see what happens.
With governments this is basically impossible. You can't run controlled experiments against governments that are similar in all aspects but one. But it is still useful to study governments if we want to design good ones. You can make a good argument that much of America's success is the result of the Founding Fathers studying the many forms of government that preceded them.
I would argue all other humanities are essentially the same. Literature and philosophy are collections of "experiments" conducted and suppositions made by our predecessors about how to live good lives. English composition is about how humans can effectively communicate in that language. Etc, etc. Are the various stories, rules of thumb, and bits of wisdom in these disciplines scientifically rigorous? Of course not. They can't be. But they can still improve our odds of reproducing some desirable effect, and that makes them knowledge worth having.
