here is a thing:
to investigate the problem, you untangle (to the best of your ability) the thing.
this is what you find:
to improve the system, you first break it along one of the component parts:
the system is complete, but the thing tangles in the same general way as it did before.
now the thing is truly ugly, and you investigate further—what makes the thing ugly? can the whole be saved from its constitutive parts?
the more you study and the more you learn, the more you begin to hate the things between the constitutive parts of the thing:
but now you can no longer hate the thing;
you and the thing share a profound reality.
now you empathize with the thing.
