Concept
Implicate and explicate order
Summary
Implicate order and explicate order are ontological concepts for quantum theory coined by theoretical physicist David Bohm during the early 1980s. They are used to describe two different frameworks for understanding the same phenomenon or aspect of reality. In particular, the concepts were developed in order to explain the bizarre behaviors of subatomic particles which quantum physics describes and predicts with elegant precision but struggles to explain.
In Bohm's Wholeness and the Implicate Order, he used these notions to describe how the appearance of such phenomena might appear differently, or might be characterized by, varying principal factors, depending on contexts such as scales. The implicate (also referred to as the "enfolded") order is seen as a deeper and more fundamental order of reality. In contrast, the explicate or "unfolded" order includes the abstractions that humans normally perceive. As he wrote:
In the enfolded [or implicate] order, space and time are no longer the dominant factors determining the relationships of dependence or independence of different elements. Rather, an entirely different sort of basic connection of elements is possible, from which our ordinary notions of space and time, along with those of separately existent material particles, are abstracted as forms derived from the deeper order. These ordinary notions in fact appear in what is called the "explicate" or "unfolded" order, which is a special and distinguished form contained within the general totality of all the implicate orders ().
The notion of implicate and explicate orders emphasizes the primacy of structure and process over individual objects. The latter are seen as mere approximations of an underlying process. In this approach, quantum particles and other objects are understood to have only a limited degree of stability and autonomy.
Bohm believed that the weirdness of the behavior of quantum particles is caused by unobserved forces, maintaining that space and time might actually be derived from an even deeper level of objective reality.
