Most leadership development focuses on changing behavior — but behavior is driven by something deeper: the beliefs, values, and assumptions that shape how we see ourselves, our work, and the people around us. When those foundations go unexamined, even well-intentioned behavior change tends not to hold.
The SANE model brings philosophy into the coaching conversation. Grounded in my training as both a Harvard-trained psychiatrist and a philosopher, it uses four foundational thinkers — Socrates, Aristotle, Nietzsche, and the Existentialists — to structure the kind of deep self-inquiry that supports lasting leadership growth.
The SANE Framework
SANE is a mnemonic I developed for bringing philosophical inquiry into executive coaching sessions. Each letter represents a major tradition of Western philosophy — Socrates, Aristotle, Nietzsche, and the Existentialists — and a corresponding guiding question. The questions have no right or wrong answers. Their purpose is to surface hidden assumptions, clarify values, and illuminate the relationship between how a client thinks and how they lead.
My approach draws on philosophical traditions beyond the Western canon as well. I have written about the relevance of Taoist concepts — particularly wu-wei, the practice of effortless natural action — for executives navigating transitions into senior strategic roles. The SANE framework provides the core structure; the depth and direction of inquiry is customized for each client.
S — Socrates: The Examined Life
Guiding question: What is the most challenging question someone could ask me about my current approach?
Socrates believed that the unexamined life is not worth living — and that genuine self-knowledge requires the willingness to be uncomfortable. The Socratic method proceeds through questioning: surfacing hidden assumptions, exposing contradictions, and pressing past easy answers to find something truer and more defensible.
In coaching, this takes the form of probing questions that a client might prefer not to be asked. What am I assuming that might not be true? Where am I avoiding a difficult conversation? What would I most not want a trusted colleague to notice about my leadership? Clients who engage seriously with Socratic inquiry often describe it as both unsettling and clarifying — the discomfort of seeing what has been obscured, followed by the relief of having something real to work with.
A — Aristotle: Character and Flourishing
Guiding question: What character virtues are most important to me and how will I express them?
Aristotle argued that a good human life is one of eudaimonia — often translated as flourishing or well-being — and that this requires the development and expression of character virtues: courage, honesty, practical wisdom, fairness, and others. Virtues, for Aristotle, are not innate; they are habits developed through repeated practice. We become honest by acting honestly, courageous by acting courageous.
For leaders, the Aristotelian question is fundamentally about identity: what kind of person do I want to be, and is the way I am leading consistent with that? Articulating core values is also, as I have written in the Harvard Business Review, one of the most effective and underutilized strategies for managing stress. Leaders who know what they stand for are far less destabilized by uncertainty, criticism, and adversity than those who have not done this work.
N — Nietzsche: Authenticity and Self-Mastery
Guiding question: How will I manage my self-interest and act in accordance with my chosen values and highest good?
Nietzsche is often misread as a champion of raw self-interest, but his actual concern was self-mastery and authenticity. His concept of the will to power is not about dominating others — it is about the disciplined effort to become fully oneself, to create a life guided by values one has genuinely chosen rather than simply inherited from family, culture, or convention.
In coaching, this translates into a rigorous examination of what drives a client’s ambition and decision-making. Whose expectations am I living up to, and are they my own? What would I do differently if I were free of the need for external validation? How do I navigate the tension between my own advancement and the wellbeing of my team and organization? These are not comfortable questions, but they are essential for any leader who wants to lead authentically rather than reactively.
E — Existentialists: Radical Responsibility
Guiding question: How will I take full responsibility for my choices and the outcomes to which they lead?
Jean-Paul Sartre and the Existentialists argued that human beings are radically free — and that this freedom carries an inescapable responsibility for our choices. Sartre described what he called bad faith: the tendency to deny freedom by blaming circumstances, other people, or forces beyond our control for outcomes we could have shaped differently. Authentic existence, by contrast, means owning the choices one has made and accepting their consequences.
In a leadership context, existentialist inquiry is about accountability without excuse. It asks clients to look honestly at where they have abdicated responsibility, rationalized failure, or allowed themselves to be shaped by circumstances rather than the other way around. This is demanding work — but clients consistently report that it is among the most freeing insights they gain in coaching: recognizing that they have more agency than they had believed.

Frequently Asked Questions
SANE is a mnemonic framework developed by Dr. David Brendel that brings four major Western philosophical traditions into the coaching process. Each letter stands for a philosopher or school of thought — Socrates, Aristotle, Nietzsche, and the Existentialists — along with a corresponding guiding question. Together, the four questions promote self-examination, values clarification, authentic self-expression, and personal accountability.
Most leadership development focuses on behavior change — but behavior is driven by deeper factors: beliefs, values, and assumptions that rarely get examined. Philosophy provides structured tools for examining these foundations. As Dr. Brendel has written in the Harvard Business Review, when leaders clarify what they stand for, they make better strategic decisions, manage stress more effectively, and lead with greater consistency and authenticity.
The PITTA model provides a structured process for working through any leadership or career challenge — from initial pause and inquiry through action and assessment. The SANE model operates at a deeper philosophical level, examining the beliefs and values that drive behavior in the first place. In practice, the two frameworks complement each other: PITTA guides the overall coaching arc while SANE deepens the reflective inquiry within it.
No. While the SANE mnemonic focuses on four major Western thinkers, the coaching approach draws on diverse philosophical traditions, including Eastern and non-Western thought. Dr. Brendel has written about the relevance of Taoist concepts — particularly wu-wei, the practice of effortless natural action — for executives navigating transitions into senior strategic leadership roles.
Philosophical counseling places primary emphasis on self-understanding and philosophical inquiry as valuable in their own right, independent of any specific career goal. Most Leading Minds coaching engagements integrate philosophical inquiry as one element within a broader process that also includes action planning and behavior change. Some clients specifically elect to pursue philosophical counseling as a dedicated practice. Dr. Brendel works with each client to determine the balance that fits their goals.
