Why is the brain divided? The difference between right and left hemispheres has been puzzled over for centuries. In a book of unprecedented scope, Iain McGilchrist draws on a vast body of recent brain research, illustrated with case histories, to reveal that the difference is profound - not just this or that function, but two whole, coherent, but incompatible ways of experiencing the world. The left hemisphere is detail-oriented, prefers mechanisms to living things, and is inclined to self-interest, where the right hemisphere has greater breadth, flexibility and generosity. This division helps explain the origins of music and language, and casts new light on the history of philosophy, as well as on some mental illnesses. In the second part of the book, he takes the reader on a journey through the history of Western culture, illustrating the tension between these two worlds as revealed in the thought and belief of thinkers and artists, from Aeschylus to Magritte. He argues that, despite its inferior grasp of reality, the left hemisphere is increasingly taking precedence in the modern world, with potentially disastrous consequences. This is truly a tour de force that should excite interest in a wide readership.
Honing theory posits that creativity arises due to the self-organizing, self-mending nature of a worldview (see above), and that it is by way of the creative process the individual hones (and re-hones) an integrated worldview. Honing theory places equal emphasis on the externally visible creative outcome and the internal cognitive restructuring brought about by the creative process. Indeed one factor that distinguishes it from other theories of creativity is that it focuses on not just restructuring as it pertains to the conception of the task, but as it pertains to the worldview as a whole. (...)Thus another distinguishing feature of honing theory is that the creative process reflects the natural tendency of a worldview to attempt to resolve dissonance and seek internal consistency amongst its components, whether they be ideas, attitudes, or bits of knowledge; it mends itself as does a body when it has been injured.
Yet another central, distinguishing feature of honing theory is the notion of a potentiality state. Honing theory posits that creative thought proceeds not by searching through and randomly ‘mutating’ predefined possibilities, but by drawing upon associations that exist due to overlap in the distributed neural cell assemblies that participate in the encoding of experiences in memory. Midway through the creative process one may have made associations between the current task and previous experiences, but not yet disambiguated which aspects of those previous experiences are relevant to the current task. Thus the creative idea may feel ‘half-baked’. It is at that point that it can be said to be in a potentiality state, because how it will actualize depends on the different internally- or externally-generated contexts it interacts with.
Honing theory can account for many phenomena that are not readily explained by other theories of creativity. For example, creativity was commonly thought to be fostered by a supportive, nurturing, trustworthy environment conducive to self-actualization. However, research shows that creativity is actually associated with childhood adversity, which would stimulate honing.
Other experiments show that different works by the same creator exhibit a recognizable style or 'voice', and that this same recognizable quality even comes through in different creative outlets. This is not predicted by theories of creativity that emphasize chance processes or the accumulation of expertise, but it is predicted by honing theory, according to which personal style reflects the creator's uniquely structured worldview.
Og som altså også lader sig forbinde med min teori om at den særligt kreative personlighed er - i hvert fald delvis - et produkt af særlige fantasiaktiverende og -stimulerende erfaringer (savn, længsel, ønsker) i barndom og ungdom.
Disse erfaringer, antager jeg, levere stimulerende impulser til en særlig stærk udvikling af default-netværket i hjernen - og det er altså erfaringer som man kan konstatere at rigtig mange forfattere, maler, forskere, etc. har med i deres mentale bagage fra barndommen af.
