# The Conscious Field > A field guide to consciousness ## Pages - [Home](https://quantum-mind.org/): The Conscious Field explains the leading theories of consciousness, the research on altered states, meditation and near-death experiences, with every claim graded by its level of evidence. - [Editorial Policy](https://quantum-mind.org/about/editorial-policy/): How we choose topics, use sources, grade evidence and correct mistakes. - [Affiliate Disclosure](https://quantum-mind.org/affiliate-disclosure/): The Conscious Field is reader-supported. - [Privacy Policy](https://quantum-mind.org/privacy/): KEVALEX SAS, 4 Route du Sept-Un, 16100 Boutiers-Saint-Trojan, France. Contact: via our contact page. - [Legal Notice](https://quantum-mind.org/legal-notice/): quantum-mind.org (The Conscious Field) is published by KEVALEX, a French simplified joint-stock company (SAS) with share capital of €4,000, registered with the Angoulême Trade and Companies Register under number 812 834 612 (SIRET 812 834 612 00028). - [Contact](https://quantum-mind.org/contact/): Spotted an error, have a question or want to suggest a topic? We read every message. - [About The Conscious Field](https://quantum-mind.org/about/): A field guide to consciousness: curious, rigorous and open. - [The Library](https://quantum-mind.org/library/): A short, opinionated reading list. For each book: what it argues and who it is for. We include books we disagree with when they matter. - [Start Here](https://quantum-mind.org/start-here/): Six steps, roughly an hour of reading, from the basic question to the frontiers of research. - [The Evidence Meter](https://quantum-mind.org/evidence-meter/): Consciousness research mixes solid findings, live controversies and bold speculation. We label every major claim so you always know which is which. - [Psychedelics and Consciousness: The Research](https://quantum-mind.org/psychedelics-and-consciousness/): Why some substances change perception and the sense of self so profoundly, and what that teaches about how the brain builds experience. - [The Science of Lucid Dreaming](https://quantum-mind.org/lucid-dreaming-science/): Knowing you are dreaming while you dream was once dismissed as anecdote. A simple experimental trick turned it into a research field. - [The Golden Ratio: Fact, Myth and Mathematics](https://quantum-mind.org/golden-ratio-myths/): φ is a genuinely remarkable number. It is also the subject of more confident nonsense than almost any other piece of mathematics. - [IIT vs Global Workspace: What the Adversarial Test Found](https://quantum-mind.org/iit-vs-global-workspace/): For the first time, rival theories of consciousness agreed in advance on experiments that could count against them. Neither came out unscathed. - [Integrated Information Theory (IIT) in Plain English](https://quantum-mind.org/integrated-information-theory/): IIT starts not from the brain but from experience itself, and arrives at some of the boldest predictions in consciousness science. - [Global Workspace Theory: How the Brain Broadcasts](https://quantum-mind.org/global-workspace-theory/): One of the most influential scientific theories of consciousness treats awareness as information that wins a competition and is broadcast across the brain. - [The Hard Problem of Consciousness, Explained](https://quantum-mind.org/hard-problem-of-consciousness/): Why does it feel like anything to be you? The question David Chalmers named in 1995 still divides philosophers and scientists. - [Sacred Geometry: Mathematics, History and Myth](https://quantum-mind.org/sacred-geometry/): Circles, ratios and solids that have fascinated builders and philosophers for millennia. - [Near-Death Experiences: What Science Knows](https://quantum-mind.org/near-death-experiences/): Tunnels, light, a sense of peace, seeing one’s own body from above: near-death experiences are reported across cultures. - [Meditation and the Brain: What Research Shows](https://quantum-mind.org/meditation-neuroscience/): Meditation is one of the most studied contemplative practices in neuroscience. - [Altered States of Consciousness: What They Reveal](https://quantum-mind.org/altered-states/): Every night the brain switches consciousness off and on, and changes its character in dreams. Anaesthesia and psychedelics change it in other ways. - [Panpsychism: Is Consciousness Everywhere?](https://quantum-mind.org/panpsychism/): Once dismissed as mysticism, panpsychism is now defended by serious philosophers. What it claims, why it appeals, and the problem it has never solved. - [Is Consciousness Quantum? The Main Theories Compared](https://quantum-mind.org/quantum-consciousness/): Quantum physics and consciousness are both mysterious, which makes it tempting to link them. Some serious scientists have. - [The “Quantum Soul” Hypothesis, Examined](https://quantum-mind.org/quantum-soul-hypothesis/): The suggestion that consciousness might be stored as quantum information that outlasts the body is popular online. - [Microtubules and Consciousness: What the Evidence Says](https://quantum-mind.org/microtubules-and-consciousness/): Microtubules are among the most studied structures in cell biology. The idea that they play a special role in consciousness is far newer and much less certain. - [Orch OR Explained: The Quantum Theory of Consciousness](https://quantum-mind.org/orch-or-theory/): What the Penrose–Hameroff proposal actually claims, why so many physicists and neuroscientists doubt it, and which experiments could settle the question. - [The Mathematics of Sacred Geometry, Explained](https://quantum-mind.org/2012/03/07/the-mathematics-of-sacred-geometry/): Strip away the mysticism and “sacred geometry” rests on a handful of genuinely beautiful constructions. - [Theories of Consciousness: A Field Guide](https://quantum-mind.org/overview.html): What scientists and philosophers actually mean by “consciousness”, the main theories on the table today, how they are being tested, and how much evidence stands behind each one.
