Yay for Philosophy, Psych and neuro-sci classes!!!!!!! (Western university) My apologies for improper sentence structure as I am (termed) dead tired. From wiki to save time: In a physicalist theory of mind, a concept is a mental representation, which the brain uses to denote a class of things in the world For conciousness: The primary focus is on understanding what it means biologically and psychologically for information to be present in consciousness—that is, on determining the neural and psychological correlates of consciousness. Philosophers since the time of Descartes and Locke have struggled to comprehend the nature of consciousness and pin down its essential properties. Issues of concern in the philosophy of consciousness include whether the concept is fundamentally valid; whether consciousness can ever be explained mechanistically; whether non-human consciousness exists and if so how it can be recognized; how consciousness relates to language; whether consciousness can be understood in a way that does not require a dualistic distinction between mental and physical states or properties; and whether it may ever be possible for computing machines like computers or robots to be conscious. This is the assumed definition on the wiki but you don't have to agree with parts or any of it. Consciousness is the quality or state of being aware of an external object or something within oneself. It is interesting that most definitions of conciousness are almost always based off the states of being awake or not-awake. Being awake is the opposite of the state of being asleep in which most external inputs to the brain are excluded from neural processing. It is just so mind blowing that only a low percentage (even then still assumed) of understating of the brain has been discovered so far. But I guess it makes sense as it is debatably the most complex structure in the universe so far. This makes me just want to sit by the fireplace and ponder over my thoughts (especially over the idea of non-human conciousness). Without straying too far from the concept of conciousness (ex. brain waves) what are your thoughts on this topic?
