What is Consciousness: Definition and 232 Discussions

Consciousness, at its simplest, is sentience or awareness of internal and external existence. Despite millennia of analyses, definitions, explanations and debates by philosophers and scientists, consciousness remains puzzling and controversial, being "at once the most familiar and most mysterious aspect of our lives". Perhaps the only widely agreed notion about the topic is the intuition that it exists. Opinions differ about what exactly needs to be studied and explained as consciousness. Sometimes, it is synonymous with the mind, and at other times, an aspect of it. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes some kind of experience, cognition, feeling or perception. It may be awareness, awareness of awareness, or self-awareness. There might be different levels or orders of consciousness, or different kinds of consciousness, or just one kind with different features. Other questions include whether only humans are conscious, all animals, or even the whole universe. The disparate range of research, notions and speculations raises doubts about whether the right questions are being asked.Examples of the range of descriptions, definitions or explanations are: simple wakefulness, one's sense of selfhood or soul explored by "looking within"; being a metaphorical "stream" of contents, or being a mental state, mental event or mental process of the brain; having phanera or qualia and subjectivity; being the 'something that it is like' to 'have' or 'be' it; being the "inner theatre" or the executive control system of the mind.

    Does consciousness cause Wave-Function collapse?

    I was wondering if consciousness really causes the wave-function to collapse, and if this is the reason why our behavior is not erratic. Thanks!

    Does Quantum Mechanics Necessitate Consciousness?

    There is soooo much misinformation out there that for the non-physicist, it is difficult to know whether to trust one source or not. So, one thing I do not understand is, based on what I've read, how QM does or does not require consciousness. It seems a debate that has been going on almost...

    The Physics of Consciousness by Dr. Evan Harris Walker

Why didn't they default to Bohr's interpretation, that an interaction with a geiger-counter, or any classically...
