Support Aeon Donate now What is the best way to understand consciousness? But the rise of modern neuroscience has seen a more pragmatic approach gain ground: Its key is to recognise that explaining why consciousness exists at all is not necessary in order to make progress in revealing its material basis — to start building explanatory bridges from the subjective and phenomenal to the objective and measurable.
In my work at the Sackler Centre for Consciousness Science at the University of Sussex in Brighton, I collaborate with cognitive scientists, neuroscientists, psychiatrists, brain imagers, virtual reality wizards and mathematicians — and philosophers too — trying to do just this.
And together with other laboratories, we are gaining exciting new insights into consciousness — insights that are making real differences in medicine, and that in turn raise new intellectual and ethical challenges. In my own research, a new picture is taking shape in which conscious experience is seen as deeply grounded in how brains and bodies work together to maintain physiological integrity — to stay alive.
But there is an alternative, which I like to call the real problem: There are some historical parallels for this approach, for example in the study of life. Once, biochemists doubted that biological mechanisms could ever explain the property of being alive.
Today, although our understanding remains incomplete, this initial sense of mystery has largely dissolved. Biologists have simply gotten on with the business of explaining the various properties of living systems in terms of underlying mechanisms: In the same way, tackling the real problem of consciousness depends on distinguishing different aspects of consciousness, and mapping their phenomenological properties subjective first-person descriptions of what conscious experiences are like onto underlying biological mechanisms objective third-person descriptions.
A good starting point is to distinguish between conscious level, conscious content, and conscious self.
Conscious level has to do with being conscious at all — the difference between being in a dreamless sleep or under general anaesthesia and being vividly awake and aware. Conscious contents are what populate your conscious experiences when you are conscious — the sights, sounds, smells, emotions, thoughts and beliefs that make up your inner universe.
And among these conscious contents is the specific experience of being you. This is conscious self, and is probably the aspect of consciousness that we cling to most tightly.
What are the fundamental brain mechanisms that underlie our ability to be conscious at all? Importantly, conscious level is not the same as wakefulness.
So what underlies being conscious specifically, as opposed to just being awake? Rather, consciousness seems to depend on how different parts of the brain speak to each other, in specific ways.
A series of studies by the neuroscientist Marcello Massimini at the University of Milan provides powerful evidence for this view. In dreamless sleep and general anaesthesia, these echoes are very simple, like the waves generated by throwing a stone into still water.
But during conscious states, a typical echo ranges widely over the cortical surface, disappearing and reappearing in complex patterns. Excitingly, we can now quantify the complexity of these echoes by working out how compressible they are, similar to how simple algorithms compress digital photos into JPEG files.
Complexity measures of consciousness have already been used to track changing levels of awareness across states of sleep and anaesthesia. The promise is that the ability to measure consciousness, to quantify its comings and goings, will transform our scientific understanding in the same way that our physical understanding of heat as average molecular kinetic energy depended on the development, in the 18th century, of the first reliable thermometers.
Lord Kelvin put it this way: This is where new theoretical ideas about consciousness come into play. Looking past the desk in front of me through the window beyond, I have never before experienced precisely this configuration of coffee cups, computers and clouds — an experience that is even more distinctive when combined with all the other perceptions, emotions and thoughts simultaneously present.
Consciousness is integrated in the sense that every conscious experience appears as a unified scene. We do not experience colours separately from their shapes, nor objects independently of their background. The many different elements of my conscious experience right now — computers and coffee cups, as well as the gentle sounds of Bach and my worries about what to write next — seem tied together in a deep way, as aspects of a single encompassing state of consciousness.Philosophy of Dreaming.
According to Owen Flanagan (), there are four major philosophical questions about dreaming: 1. How can I be sure I am not always dreaming?
Fideisms Judaism is the Semitic monotheistic fideist religion based on the Old Testament's ( BCE) rules for the worship of Yahweh by his chosen people, the children of Abraham's son Isaac (c BCE)..
Zoroastrianism is the Persian monotheistic fideist religion founded by Zarathustra (cc BCE) and which teaches that good must be chosen over evil in order to achieve salvation.
There are two challenges to this view.
First, there is the estimate that only about 10% of the minds work is made up of conscious thought and secondly, this view does not explain those random events created within the mind. The two functions that the capabilities of the conscious mind can address are: Its ability to direct your focus.
Issues of concern in the philosophy of consciousness include whether the concept is Locke defined consciousness as "the perception of what passes in a man's own mind". His essay influenced the 18th-century view of and limited conscious processes and fast, parallel and extensive unconscious ones.
