意识最神秘的一面是，它是作为一种主观感觉而被感觉到的。这里提出的理论旨在解释这一特定方面。该理论既包括可能涉及的计算，也包括在大脑的神经生物学中实现计算的方式。假设大脑对个体自身的进化适应性进行内部评估，这可能会产生一种特殊的、不同形式的因果关系。传递适合度估计的组成部分(无论是外部使用还是内部使用)需要将它们倒置。这种倒置可以由哺乳动物大脑中的丘脑皮质反馈回路执行，如果该回路以切换的两阶段模式运行的话。第一个(无意识)阶段产生正向估计，而第二个(有意识)阶段颠倒这些估计。有人认为，倒置产生了另一种特殊的、独特的因果关系形式，这种因果关系在空间上是局部的，似乎是作为意识的感觉来感觉的。
The most enigmatic aspect of consciousness is the fact that it is felt, as a subjective sensation. The theory proposed here aims to explain this particular aspect. The theory encompasses both the computation that is presumably involved and the way in which that computation may be realized in the brain’s neurobiology. It is assumed that the brain makes an internal estimate of an individual’s own evolutionary fitness, which can be shown to produce a special, distinct form of causation. Communicating components of the fitness estimate (either for external or for internal use) requires inverting them. Such inversion can be performed by the thalamocortical feedback loop in the mammalian brain, if that loop is operating in a switched, dual-stage mode. A first (nonconscious) stage produces forward estimates, whereas the second (conscious) stage inverts those estimates. It is argued that inversion produces another special, distinct form of causation, which is spatially localized and is plausibly sensed as the feeling of consciousness.
