imigration borders and boundaries

Imigration of ideas, knowledge and skills from domains and disciplines is the main topic of this text.

Very often is visible that ideas can imigrate from one domain to another to 'fix' and fit the issues and characteristics there.

Boundaries between disciplines are seen when a newcomer(idea or skill) appears and the contrast to the already existing knowledge is high. Soon after the masses become more homogeneous and then there is asimilation or integration. In the second case the differences will be kept and enrich the cultural scene.

Boundaries can be seen also when a domain does not have enough knowledge to explain the facts, when the events are beyond reasoning. Then the sense of frontiers is almost tangible. One can feel it with their senses, the feeling becomes somatic. One can start to become aggresive, sad or even faint.

When the discipline does not know enough, the boundaries are even clearer.  An individual may feel lost. It separates from the group instantly, having to deal with this uncertainty, of its own existence towards the unknown.

Thus uncertainty is not the problem. But the approach to it. The individual working within the discipline, for or towards it.
But wasn't the discipline just constracted?
A collective effort of many other entities, humans, or knowledge, object, and nature?
