Thomas Metzinger has empirically collected 1,500 accounts of people experiencing consciousness without self, mostly through meditation and sometimes through psychedelics, showing that pure awareness—consciousness stripped of self—is a real and accessible phenomenon.

Materialism cannot adequately explain consciousness because emergence—the claim that consciousness emerges from matter—lacks explanatory power when pressed; it sounds like 'abracadabra' (magical thinking).

The Secret Life of Plants (1970s) made outrageous claims (plants like Mozart, can identify murderers in lineups) that were completely discredited, set back real plant research, and warned about the danger of pseudoscience in consciousness studies.

Sentience is basic awareness of environment and the ability to find valence (positive or negative) in environmental changes and to move toward or away from those changes; this may be a property of life itself, including unicellular organisms and possibly plants.

Michael Levin argues that neurons and DNA are overrated as shapers of life because nature is too unpredictable for evolution to hardwire all responses; instead, evolution creates cognitive beings that respond intelligently to novel situations they cannot make decisions within their lifetime.

Michael Levin proposes that a third force shapes organisms: platonic patterns (goal-driven experience, sense of purpose, intention) that exist independently—similar to how mathematical patterns preexist mathematics—and that organisms 'ingressively' participate in or embody these patterns.

Everyone experiences pure awareness—consciousness without self—for 500 milliseconds (or 750 milliseconds to a full second in unfamiliar settings) upon waking, during which there is a lag before the self reconstitutes and 'the story starts.'

Russell Hurlburt has spent 50 years developing a portable beeper device to sample people's inner experience at arbitrary moments; his research reveals that most people do not think in words (contrary to common assumption), and that there are four basic types of inner experience: verbal, imagistic, unsymbolized thought, and very little inner life.

Consciousness is an extraordinary gift—a private space where we have complete privacy and can think whatever we want. Yet we squander this gift, taking it for granted and not appreciating the mystery and wonder of having subjective experience.

Novelists and poets know more about consciousness than neuroscientists because they study the contents and felt quality of consciousness, while neuroscientists study only neural mechanisms.

Feelings are fundamental to consciousness and distinct from thoughts; it is unclear whether machines can have genuine feelings, and claiming machines have feelings (without embodied vulnerability and mortality) is unfounded.

Kingsan Man, a consciousness researcher protege of Antonio Damasio, initially believed robots could have genuine feelings through sensory feedback, but after a 5-MeO-DMT experience, concluded there is a 'spark of divinity' in humans that robots will never possess.

David Hume discovered in the 1740s that introspection reveals only thoughts, perceptions, and feelings—never a thinker, perceiver, or feeler; consciousness without an underlying subject is accessible through direct introspection.

Meditation for hours without distraction can produce a state of consciousness different from ordinary consciousness—characterized by spontaneous thought, freedom from planning, and a kind of presence that contrasts with goal-oriented thinking.

The self is a social construct, maintained through friction and interaction with others; when social interaction is removed (silence, no eye contact), the self melts and becomes permeable.

The hard problem of consciousness is often framed as an issue of subjectivity—the subjective first-person nature of experience—which third-person objective science cannot access; but if consciousness can exist without a self, then subjectivity is not essential to consciousness, making the problem potentially more tractable by removing the 'subject' requirement.

There is a thread of personal continuity connecting one to one's childhood self, but this thread is constructed through memory and narrative; it is unclear whether it represents a real metaphysical continuity or is a functional illusion created to organize experience.

Plants can learn and remember, and some plants have longer memory spans than fruit flies—experiments show plants can see and respond to environmental stimuli.

Levin's work is largely ignored in biology but has found significant interest among researchers in computation and philosophy who appreciate its challenge to the neurocentric paradigm.

Pollan is agnostic about transmission theories of consciousness because he doesn't know how to prove them or whether they could be proved to anyone's satisfaction—the fundamental problem with metaphysical ideas.
