History can be divided in pre-classicism, classicism, modernism, and postmodernism. Pre-classicism is a collection of knowledge accumulated over hundreds of thousands of years until Greece, classicism over few thousand years since Greece, modernism over a century or so since 18th century, and postmodernism over few decades in the second half of 20th century. Classicism, modernism, and postmodernism removed some knowledge from previous periods, causing a drastic contemporary reduction in knowledge and increase in risk and values.

Metamodernism, coming after postmodernism, aims to restore the lost knowledge from each period making it available for contemporary use. This is enriching knowledge from each of the periods making it safer and more valuable. Modernism and postmodernism especially had little time to develop knowledge yet have great power and are therefore very unsafe. Their risks and quality would be lowered by adding pre-classical and classical knowledge.

Centralized power system is always changed by the power of its members. While it changes its members it is also changed by its members. This is a constant presence in all power centralization.

Openness allows the centralized power system and its members to formalize and control this power exchange. Openness makes this power relationship transparent and improves the benefits for both centralized power and its members.

Without openness, a closed centralized power system is still changed but most likely in a damaging way, which then also corrupts the effect over its members.

Centralized power systems are always changed by its members, and they have a choice to make it beneficial for all through openness, or make it damaging to all by being closed.

The rate of change is accelerating reducing the protection of traditional or empirical knowledge. This accelerated change is called hyper-change. Hyper-change will continue to accelerate. To avoid increase of damage caused by hyper-change it is necessary to apply openness and agility in the hyper-change process.

Openness will allow collection of real-time knowledge which can be used for prevention and reduction of damage. Agility will add controlled stops in the hyper-change process allowing adaptation to the openness knowledge.

Metamodernism is valuable for including all system members, visible and not visible, in openness. Metamodernism is currently the most inclusive approach to knowledge exchange and it decreases overall damage caused by hyper-change.

Grand narratives, mass media, and hyper-centralized power can not exist without each other. Their total opposites are personal experiences, personal connections, and small group cooperations, such as family. They are extreme sides of the spectrum with many more options in-between.

Our fulfillment requires participation in both extremes and all options in between. We understand the world in narratives and we need all types of narratives – small and grand – to understand our function.

While all narratives can be wrong, grand narratives, mass media, and hyper-centralization are too complex to fix quickly and damage they cause is great. Damage from great narratives is caused by the conflict with personal stories, and between the grand narratives competing for power.

The expansion of mass media is forcing generalization of grand narratives and creating bigger conflicts between personal and grand, and also between different grand narratives. The speed of change is also accelerating and does not allow time for adaptation.

Without hyper-centralization and such high reaching mass media, individuals required much less energy to balance the grand narratives with more personal ones. Changes and conflicts were slower and smaller giving us time to adapt and repair. Now extreme generalization and speed of change are creating internal individual conflicts which do not have the time to be resolve.

Solution to this is openness, which reduces the conflict between grand and personal, but also slows down generalized changes and conflicts. This will give more time to individuals to process the changes and minimize damage.
