The Full Spectrum of Awareness — Perception, Emotion, and Altered States Explained | Chapter 2 of Then I Am Myself the World

Chapter 2 of Then I Am Myself the World: What Consciousness Is and How to Expand It by Christof Koch examines the incredible diversity of human subjective experience. This chapter moves beyond the origins of consciousness and into the lived reality of awareness itself—how we perceive, feel, reflect, dream, and shift through varying states of mind. The video summary embedded below expands on these ideas for learners who want a guided exploration of the chapter’s core themes.

Here is the book cover associated with this chapter:

Book cover

Mapping the Varieties of Conscious Experience

Koch structures this chapter around phenomenology—the study of experience as it is lived from the first-person perspective. He draws on William James’s famous metaphor of the “stream of consciousness” to illustrate how awareness is not static but constantly evolving. In this stream, perceptions, thoughts, emotions, and bodily sensations flow, merge, and transform in a continuous process of becoming.

Conscious life is never singular. It is composed of countless micro-experiences that together form the rich texture of what it feels like to be human. This chapter offers a framework for understanding those layers, beginning with the senses and extending into complex emotions and altered states.

The Sensory Foundations of Awareness

Koch emphasizes that perceptual experience extends far beyond the five traditional senses. Human beings inhabit a multisensory world shaped by:

  • Exteroception: Vision, hearing, touch, smell, and taste
  • Interoception: Awareness of internal bodily states like hunger, heart rate, and breath
  • Proprioception: The sense of where the body is positioned in space

Together, these systems generate a continuous flow of perceptual input. Consciousness stitches these sensations into a coherent whole, enabling us to navigate the world and maintain a stable sense of presence.

The Emotional Landscape of Consciousness

Beyond sensory input, emotional experience forms the second major facet of conscious life. Koch explores a spectrum ranging from basic emotional states to culturally specific, deeply textured emotions. These include:

  • Basic emotions: joy, fear, anger, sadness, disgust
  • Complex emotions: guilt, hope, longing, gratitude
  • Cultural emotions: such as saudade, capturing a blend of nostalgia, loss, and longing

Emotions influence perception, shape decision-making, and color the overall tone of subjective experience. They also interact with cognition, creating a dynamic interplay between feeling, memory, and interpretation.

Inner Life: Thought, Reflection, and Meta-Consciousness

This chapter also examines inner speech, narrative thinking, and the ability to reflect on one’s own mind. Koch distinguishes between:

  • Self-awareness: recognizing oneself as the subject of experience
  • Meta-consciousness: becoming aware of one’s own awareness

These higher-layer processes allow us to evaluate thoughts, question emotions, and imagine possibilities. They form the basis of introspection, creativity, and moral reasoning. When engaged, the mind becomes both the experiencer and the observer—an internal dialogue that shapes identity.

Altered States and the Expansion of Conscious Experience

One of the most compelling sections of the chapter explores altered states of consciousness—conditions in which the usual boundaries of the self loosen or dissolve. Koch discusses:

  • Flow states: deeply immersive experiences where action and awareness merge
  • Dreaming and lucid dreaming: alternative worlds generated by the sleeping brain
  • Psychedelic experiences: temporary expansions or distortions of perception and selfhood
  • Meditative or mystical states: moments of profound stillness, unity, or transcendence

These states reveal the flexibility of consciousness. They show that our sense of self is not fixed but can stretch, dissolve, or reorganize depending on brain activity, cultural practices, and personal intention.

What This Chapter Reveals About Being Human

Koch’s central insight is that consciousness is not a single phenomenon—it is a vast mosaic composed of sensations, memories, emotions, reflections, and transcendent experiences. To be conscious is to experience this ongoing interplay of inner and outer worlds. Chapter 2 encourages readers to appreciate the profound diversity of their own subjective life and sets the groundwork for understanding how consciousness can deepen or expand.

Violence, Mourning, and the Ethics of Vulnerability — Rethinking Grievability and State Power | Chapter 2 of Precarious Life by Judith Butler How do we decide whose lives matter? In Chapter 2 of Precarious Life: The Powers of Mourning and Violence , Judith Butler addresses this urgent question by exploring how violence, mourning, and political vulnerability shape the very notion of humanity. In this chapter, titled "Violence, Mourning, Politics," Butler continues her critique of post-9/11 state narratives by focusing on the politics of grief—who is allowed to grieve, whose loss is acknowledged, and how public mourning is suppressed or manipulated to serve nationalistic ends. Watch the full chapter summary below from Last Minute Lecture to better understand how mourning can become an act of political resistance: Who Counts as Human? At the core of Butler’s argument lies the question: who is considered human, and who is denied that status? She asserts that politica...
