Creation takes energy. For one to create an intellectual or artistic work, or to make a certain scientific discovery, or invent some new technology, it takes a great amount of energy: both vital energy and sustained discipline (which requires constant mechanical energy) are required. These requirements are much higher in a mature civilization. One is competing with a certain degree of quality and variation of innovations, as well as a less robust energy input if one is relating one's efforts to an existing framework. You could always go off and do something radically new, but then you run the risk of being misunderstood or ignored, at least for the duration of your life, which is generally what radical innovators are up against anyways. Newness requires mass, or a certain threshold of activated bodies that assent to or agree with the thrust of the new object in question.
An expenditure of creative energy attracts sympathetic energies; part of the point of creating is communicating, or sharing energy. This energy bursts forth and decays, or else various points of energetic expression form positive feedback loops with each other and new artifacts are generated rapidly and in abundance (possibly with new institutions to administrate the distribution of those artifacts), which then proceed to decay over a greater timespan and scope.
This decay is expressed socially in the strictures of convention. We don't entirely know why, but not everyone is hypersensitive and creative. What happens is a functional equivalent of a cargo cult forms around the object of creation in question, attempting to emulate its creator's existence by discussing said objects, following various sets of instructions relating to the object, or attempting to negotiate socially for the highest proximal location to the object.
The vital energy mentioned above is certainly an esoteric term, but important to creation. Creatives seem to have the tendency of becoming decoupled from existing social circuits, perhaps through personal constitution or associated life traumas or both, who lose the ability to communicate effortlessly through conventional networks, but who, being human, must communicate nevertheless and be understood, which necessitates a vehicle, a creative work. This diversion of energy occurs on its own, with passionate expression finding an outlet out of necessity, oftentimes concentrating and intensifying in the process. However, what else is required is a strong character with the discipline to apply repetitive acts to perfect a given vehicle of creation (which requires willpower and of course mechanical energy, or simply nutrition and other related resources).
Those that lack the ability but still wish to share the expressive energy of creation may do so through others, either socially or through instrumentalization - that is, manipulating others of ability into organized arrangements which produce a certain effect that can be effectively converted into a proprietary format, so that the manipulator can derive enjoyment from creation without creating. There are also those that are more ambitious, but lack ability, so they become social climbers or tyrants. A tyrant is a probably a failed creative. A tyrant will share his or her being through force.
Now, I'm tempted to place values on these phenomena, and really I already have, since our language contains such potent emotional baggage. But in the end I'd rather state that these phenomena simply occur, and that is all there is to it.
