What is Consciousness?
Consciousness refers to the state of being aware—of one’s surroundings, internal sensations, thoughts, and the experience of being a subject to whom things appear. It encompasses both phenomenal consciousness (the qualitative, subjective “what it’s like” of experience, such as the redness of red or the pain of a headache) and access consciousness (information available for reasoning, report, and behavioral control). While neuroscience investigates consciousness through brain activity and neural correlates, philosophy grapples with the “hard problem”—why and how physical processes give rise to subjective experience—and contemplative traditions approach it as a field to be explored, refined, and potentially transcended through direct investigation.
The term carries different emphases across disciplines. In Western philosophy and cognitive science, consciousness often denotes waking awareness as distinct from unconscious processes or sleep. In Eastern contemplative systems—particularly Vedanta, Buddhism, and Kashmir Shaivism—consciousness (Sanskrit: cit, vijñāna, citta) is treated as fundamental, either as the ground of reality itself or as a process to be understood through meditation and inquiry.
Origins & Lineage
Philosophical inquiry into consciousness appears in ancient Greek thought, with Aristotle distinguishing perception from thought in De Anima (c. 350 BCE). However, systematic first-person investigation begins earlier in the Upaniṣads (c. 800–200 BCE), which describe consciousness (ātman) as identical with ultimate reality (brahman). The Buddhist Abhidhamma literature (c. 3rd century BCE onward) provides detailed phenomenological maps of mental states and moments of consciousness (citta).
The modern Western discourse emerges with René Descartes’ Meditations on First Philosophy (1641), which placed subjective experience (cogito ergo sum) at the foundation of knowledge. John Locke introduced the English term “consciousness” in An Essay Concerning Human Understanding (1689) to describe “the perception of what passes in a man’s own mind.” William James’ The Principles of Psychology (1890) offered the first comprehensive empirical treatment, coining “stream of consciousness” to capture its fluid, continuous character.
The 20th century saw divergent paths: behaviorism dismissed consciousness as scientifically inaccessible, while phenomenology (Edmund Husserl, Maurice Merleau-Ponty) developed rigorous methods for describing first-person experience. The field was revitalized in the 1990s—the “Decade of the Brain”—with Francis Crick and Christof Koch’s neural correlates research, David Chalmers’ articulation of the “hard problem” (1995), and increasing dialogue between contemplative practitioners and neuroscientists, notably through the Mind & Life Institute (founded 1987).
How It’s Practiced
Consciousness is not typically “practiced” but investigated through complementary methods. Contemplative traditions offer direct techniques: Vipassanā meditation trains attention on the arising and passing of sensory experience to observe consciousness in action. Zen kōan practice disrupts habitual thought to reveal awareness prior to conceptualization. Self-inquiry (ātma-vicāra), taught by Ramana Maharshi, asks “Who am I?” to locate the source of the “I”-sense.
Neuroscientific research uses fMRI and EEG to identify neural activity correlated with conscious states—tracking changes during meditation, sleep stages, or anesthesia. Neurophenomenology, pioneered by Francisco Varela, combines first-person meditative training with third-person measurement to triangulate findings.
Philosophically, consciousness is explored through thought experiments (Mary’s room, philosophical zombies, the Chinese room) that probe intuitions about qualia, intentionality, and the relationship between mind and matter.
Consciousness Today
Seekers encounter consciousness teachings through mindfulness-based stress reduction (MBSR) programs, which secularize Vipassanā techniques; Zen centers offering sesshin (intensive meditation retreats); and Advaita Vedanta satsangs emphasizing recognition of awareness as one’s true nature. The Insight Meditation Society (Barre, Massachusetts), Spirit Rock (Woodacre, California), and Plum Village (France) offer extended silent retreats focused on observing consciousness.
Conferences like the Science of Consciousness (annually since 1994, Tucson) and organizations such as the Association for the Scientific Study of Consciousness bring together researchers. Popular books—Sam Harris’ Waking Up (2014), Anil Seth’s Being You (2021), Michael Pollan’s How to Change Your Mind (2018)—introduce general audiences to altered states, predictive processing models, and psychedelic research.
Online platforms host talks by teachers like Rupert Spira (non-dual awareness), Shinzen Young (mathematical models of meditation), and neuroscientists such as Giulio Tononi (integrated information theory).
Common Misconceptions
Consciousness is not synonymous with thought. Contemplative traditions emphasize consciousness as the awareness of thoughts, distinct from mental content. It is not exclusively human—debate continues regarding animal consciousness, with the 2012 Cambridge Declaration on Consciousness affirming sentience in mammals and birds.
Consciousness does not require language or self-reflection; these are specific capacities that may arise within consciousness. It is not a singular, monolithic phenomenon—research distinguishes levels (minimal consciousness in vegetative states vs. full waking awareness), contents (what we’re conscious of), and states (waking, dreaming, deep sleep, meditative absorptions).
The field has no consensus. Theories range from materialism (consciousness emerges from brain complexity) to panpsychism (consciousness is a fundamental feature of matter) to idealism (consciousness is ontologically primary). Claims of “raising” or “expanding” consciousness often conflate phenomenal states with moral or spiritual development—distinct dimensions that may or may not correlate.
How to Begin
For direct investigation, begin with a 10-day Vipassanā retreat in the S.N. Goenka tradition (dhamma.org) or an Insight Meditation introductory course. For philosophical grounding, read Thomas Nagel’s “What Is It Like to Be a Bat?” (1974) and David Chalmers’ The Conscious Mind (1996). For neuroscience perspectives, consult Stanislas Dehaene’s Consciousness and the Brain (2014) or Anil Seth’s lectures on the predictive brain.
Practice “noting”—silently labeling sensations (“hearing,” “thinking,” “tension”) for 10 minutes daily—to distinguish consciousness from its contents. Explore the Waking Up app (Sam Harris) or attend a local Zen center’s introductory zazen instruction. Approach with curiosity rather than belief; consciousness yields most readily to those who investigate it as an open question.
