« Bohm and Hiley have pointed out that physicists feel such a degree of revulsion towards non-locality that "they would prefer not to consider the idea even as a possibility". However, I would argue that, despite this prejudice, the idea of non-locality is perfectly natural and pervades much of our thinking.
[...] Inseparability, an oceanic sense, a feeling of oneness with all nature and a direct communion with others are given high value in all cultures. Poets and mystics have attempted to explore in words and image their feeling of immediate contact with all things. Such a sense of connection appears to lie outside the confines of space and time and resonates deeply with our experience of the world. Indeed, I would argue that the cluster of concepts surrounding non-locality have much to do with the operation of the mind and brain. We can begin to see this by considering how the world is dealt with in art and literature.
Much of the world's art is concerned with a non-local representation of space. Early paintings were able to integrate may different viewpoints or "perspectives" of the same event. In a painting of the life of a saint, for example, this enfoldment or overlaying took place not only in space but also in time, for events occurring at different periods are presented together. [...] A painting is more concerned with relationship than with absolute location. Its integrating force comes more from color, movement, thrust, gesture and shape rather than from position within some background "scientific" space. [...]
Such paintings treat space in a more profoundly different yet entirely natural way than is suggested by a "realistic painting" in which, generally speaking, space is portrayed from single viewpoint. This latter view had its origin in the development of perspective during the early Renaissance. The end result in hands of a painter like David, working in the late eighteenth century, is a sort of snapshot or "tableau" in which motion and change is frozen in a single instant of time and presented from the unique perspective of the artist, the objective viewer of the scene. In this way a purely local view of space had been born. Space becomes the supreme arbiter, the ground out of which relationship and structure is born. Yet it is a space defined from only one viewpoint which dominates the painting. It is not difficult to see the origin of this new objectivity in the rise of the individual, for it also heralds the appearance of the concerto, the novel and the diarist. [...]
In our own century painting has returned to the non-local order. Mainly as a result of Cézanne, space became richer, with many different perspectives and viewpoints being overlaid together. [...] Research on visual perception confirms this view for it suggests that our knowledge of the world is built out of complementary movements. What we see is the result of a complicated collection of processes involving eye movements and the revelation of different aspects of a scene which are then processed independently in different parts of the visual cortex. The building of space, through neurological processing, is complementary. All this suggests that space is never experienced as prior, or in any way divorced from events and occurrences. The notion of space as being the ground or backdrop out of which geometrical relationships and the world is built is alien to the very way we experience the world. Rather the notion of space is something that emerges out of a deeper and more complex experience and is essentially inseparable from other aspects of this experience.
Not only visual perception but also thought itself has a similar complex, overlaid quality which demands complementary viewpoints, including what could be loosely termed "non-local". It is true that certain aspects of thought have a relatively "causal" or "mechanical" order. [...] Yet in their other aspects our experiences of the world enfold and overlap, they blossom and unfold out of each other rather than following in any linear causal fashion. [...]
Similar images arise in non-local systems. A vortex is an expression of the non-linearity of a fast flowing river. It has the appearance of an isolated object for it is located in a well defined region of space, persists for a given time and may even appear to interact with other objects in the river. Nevertheless the vortex has, in a deeper sense, a non-local origin for it arises out of the movement of the whole river. [...]
David Bohm and his co-workers have demonstrated how it is possible to develop a quantum physics of non-separability using an underlying local mathematics. Bohm's curious quantum potential is determined by the wave function for the whole system, ideally by the wave function for the entire universe. [...] But this means that distant objects can still exert a strong effect on the particle—in essence the motion of the particle is determined by the whole experimental situation including the orientations of quite distant objects. In this sense the behavior of each part of the system is determined by the whole. Bohm's quantum potential implies that quantum states are basically inseparable and it allows for the non-local correlations of Bell's Theorem, and the sort of quantum wholeness stressed by Bohr. [...]
The whole subject of non-locality in physics could be compared, by way of illustration, with that of non-linearity. For two hundred years physics was able to explain a wide range of phenomena using only linear theories and by explaining nonlinear effects in terms of a linearized perturbation theory. [...] Today linearity is viewed as a special case of non-linearity that holds only under certain limiting conditions. While, in the past, physicists saw linear systems all around them, today they deal in non-linearity. It may also be possible that locality and certain forms of causality will one day be seen as limiting cases of a more general non-local holism, for our current paradigms of physics may be blinding us to different ways of seeing.
By seriously considering the ideas of non-locality, not only in the quantum theory but in a much wider context, it may be possible to develop a conception of nature that integrates more deeply with our own perception, thought and experience. Moreover, it may lead to a much deeper understanding of nature. Non-locality is not simply a matter of substituting, for the continuous manifold of space, some new mathematical formalism. It is intimately connected with the whole notion of causality, force and interaction, and with the definition of material bodies. Indeed to contemplate non-locality is to entertain a radically different conception of the universe. »
