I'm really interested in the classic philosophical question "how should we live". We all already have a set of answers to that implanted in our heads, though for most of us those answers are invisible, assumed to be "normal". Often the answers to these questions that we have, those given to us by our culture and our own conclusions are confused and at odds with themselves. Their relative invisibility makes them even harder to work with.
One way we can divide systems of culture is by their basic approach to knowledge. Some are essentially declarative (that is, they dictate the truth with finality), while others are essentially explorative (that is, they don't claim to know the truth, but rather to be seeking it). An observable pattern in explorative culture and knowledge systems is the tendency to explode into an ever broadening fractal of fields and subfields, subjects gradually separating themselves from each other into specialties. Typically, each of these subfields becomes loosely coupled with its parent, able to support itself and its assertions independently.
Declarative systems of thought, conversely, appear to absorb subjects into themselves, forming one accretion of interdependent statements. This mass of statements may wind up collected into one canonical published source. The Bible is a pretty good example of this process. The Bible is not a specifically religious book. The word "bible" literally translates from Greek as "the books". It contains cutting-edge (circa 400 BCE) thinking on natural philosophy, politics, medicine, law, history, ethics, agriculture, poetry, and spirituality, all in one massive lump.
So we are all on a journey of continuous growth. (Some of us know it more than others, and some of us only are as a part of something larger.
