Concept of Self

What is the self? Are you the same now as you were 20 years ago? Are you made of one thing or contain multiplicities? Are you your thoughts or have thoughts? There's more to Us than meets the eye.

For this episode, I sat down with researcher, coach, and lifelong explorer Heather Frost to dive into her fascinating work on the concept of self. From global travel to coaching, psychology and philosophy, Heather shares how her journey led her to ask one of life’s most fundamental questions: What is the Self? Together, we unpack the difference between self-concept and the Concept of Self, explore how different understandings of self shape behaviour and identity, and consider what this all means for coaching, adult development, and how we relate to each other. I hope you leave this conversation with a new perspective on yourself and with renewed curiosity about the complexity and beauty of our minds.

Episode Summary

00:00 – 05:30 | Origins of the Inquiry into Self
Heather’s lifelong curiosity about how people make sense of themselves, shaped by travel, philosophy, coaching, and neuroscience.

05:30 – 10:30 | Embracing Uncertainty
Immersive travel as a practice of “not knowing” — cultivating openness, resilience, and a fluid sense of self.

10:30 – 15:30 | How Not-Knowing Changes Us
Alis and Heather explore how dislocation and risk can deepen self-awareness and transform identity.

15:30 – 23:00 | Kindness, Openness, and Humility
Exposure to difference builds compassion and dissolves rigid identity boundaries.

23:00 – 31:00 | Defining Terms: Self-Concept vs. Concept of Self
Clear distinction:

  • Self-concept = beliefs about who I am

  • Concept of self = what I think the “self” is

31:00 – 39:00 | The 3 Spectrums of Self
Heather’s research reveals three key dimensions:

  1. Stability – Is self constant or evolving?

  2. Unity vs. Multiplicity – One self or many?

  3. Thoughts-as-Self vs. Thoughts-as-Patterns

39:00 – 44:30 | Why This Matters in Coaching
The Concept of Self influences agency, decision-making, and behaviour change. Coaches must listen for clues in the client's language.

44:30 – 54:00 | Adapting Coaching Approaches
Tailor your methods: future visualisation works for stable self-views; emergent experiments work better for fluid self-views.

54:00 – 1:01:00 | Reframing Limiting Beliefs
No “right” way to view the self — ask: Does this belief serve the client in their context?

1:01:00 – 1:08:00 | Links to Adult Development
Later developmental stages often correlate with fluid, multi-part understandings of self — but nuance and fit matter more than hierarchy.

1:08:00 – 1:13:00 | Practice for Coaches
Reflect on your own concept of self. Tune into how your clients relate to Self — and coach accordingly.

1:13:00 – End | Final Reflections
Heather’s hope: deeper awareness of how we understand “self” can foster more compassionate, skillful coaching — and a more tolerant world.
