Thanks to the work of a small group neuroscientists and theoretical physicists over the last few years, we may finally have found a way of analyzing the mysterious, metaphysical realm of consciousness in a scientific manner. The latest breakthrough in this new field, published by Max Tegmark of MIT, postulates that consciousness is actually a state of matter. “Just as there are many types of liquids, there are many types of consciousness,” he says. With this new model, Tegmark says that consciousness can be described in terms of quantum mechanics and information theory, allowing us to scientifically tackle murky topics such as self awareness, and why we perceive the world in classical three-dimensional terms, rather than the infinite number of objective realities offered up by the many-worlds interpretation of quantum mechanics.
Consciousness has always been a tricky topic to broach scientifically. After all, science deals specifically with effects that can be observed and described mathematically, and consciousness has heretofore successfully evaded all such efforts. In most serious scientific circles, merely mentioning consciousness might result in the rescinding of your credentials and immediate exile to the land of quacks and occultists.

Anything to avoid the prospect of having a soul, I guess.
