The nature of consciousness is considered one of science's most perplexing and persistent mysteries. We all know the subjective experience of consciousness, but where does it arise? What is its purpose? What are its full capacities? The assumption within today's neuroscience is that all aspects of consciousness arise solely from interactions among neurons in the brain. However, the origin and mechanisms of (i.e., subjective or phenomenological experience) are not understood. David Chalmers coined the term "the hard problem" to describe the difficulties in elucidating the origins of subjectivity from the point of view of reductive materialism. We propose that the hard problem arises because one or more assumptions within a materialistic worldview are either wrong or incomplete. If consciousness entails more than the activity of neurons, then we can contemplate new ways of thinking about the hard problem. This review examines phenomena that apparently contradict the notion that consciousness is exclusively dependent on brain activity, including phenomena where consciousness appears to extend beyond the physical brain and body in both space and time. The mechanisms underlying these "non-local" properties are vaguely suggestive of quantum entanglement in physics, but how such effects might manifest remains highly speculative. The existence of these non-local effects appears to support the proposal that post-materialistic models of consciousness may be required to break the conceptual impasse presented by the hard problem of consciousness.
意识的本质被认为是科学中最令人困惑且长期存在的谜团之一。我们都知晓意识的主观体验,但它从何而来?其目的是什么?它的全部能力又是什么?当今神经科学的假设是,意识的所有方面都仅源于大脑中神经元之间的相互作用。然而,意识(即主观或现象学体验)的起源和机制尚不清楚。大卫·查尔默斯创造了“难题”一词来描述从还原唯物主义角度阐明主观性起源的困难。我们认为难题的出现是因为唯物主义世界观中的一个或多个假设要么错误要么不完整。如果意识所包含的不仅仅是神经元的活动,那么我们可以思考解决难题的新思维方式。这篇综述探讨了一些明显与意识完全依赖于大脑活动这一观点相矛盾的现象,包括意识似乎在空间和时间上超越物理大脑和身体范围的现象。这些“非局部”特性背后的机制隐约暗示了物理学中的量子纠缠,但这种效应可能如何显现仍极具推测性。这些非局部效应的存在似乎支持了这样一种提议,即可能需要意识的后唯物主义模型来打破意识难题所带来的概念僵局。
