I rambled on first principles and the buddhist idea of no self, handed if off to my voice note agent and voila a long form piece helping me make sense of it.

First Principles 'I' vs. The Reality of Emptiness

Western first principles and Buddhist reductionism

Introduction

People in many cultures share an urge to strip away inherited assumptions and secondary models until they reach something they can't doubt. When a system gets cluttered with dogma or tradition, the thinkers who change it tend to take it apart down to its elements rather than patch the surface.

Western rationalism and Eastern phenomenology both did this, and they came back with very different answers about identity and reality. Descartes used systematic doubt to isolate an undeniable "I" (Cogito, ergo sum) and treated it as the first principle on which a reliable world of science, logic, and innovation could be built. The Buddha, and later Nāgārjuna, turned systematic analysis on that same "I," broke experience into five impermanent aggregates (skandhas), and found no permanent, independent self (Anattā).

That leaves the paradox this post explores. First principles thinking is the most effective framework we have for building and operating in the conditional world of the self, yet Buddhist philosophy holds that there is no permanent "I" at the core of reality.

Building the conditional world with Cartesian logic

In Western philosophy and modern engineering, first principles thinking means breaking a problem down to its most basic truths, the axioms that can't be deduced from anything else, and reasoning upward from there. The idea goes back to Aristotle, who looked for the archē (beginning or source) and the four fundamental causes of physical reality. It reached its philosophical peak during the European Enlightenment with René Descartes.

Descartes, heavily influenced by Euclidean geometry, developed what's now called Cartesian doubt: doubt every sensory impression, opinion, and unexamined belief until only what can't be doubted is left. Once he had set aside all fallible sensory data, one principle remained:

"Je pense, donc je suis" ("I think, therefore I am")

For Descartes, the thinking subject, the "I," was the foundational substance. It couldn't be reduced any further.

[Systematic Doubt] ──> [Indubitable Axiom: "Cogito / I Am"] ──> [Constructing World / Science]

This foundationalist framework made the "I" an agent that could build reliable knowledge, establish causal order, and solve hard problems from scratch. Daily life still runs on that conditional world of the self. We set goals, take responsibility, build technology, and move through social structures, and all of it depends on a working "I." Inside that world, first principles thinking is the best tool we have.

The five aggregates: taking the "I" apart

More than two thousand years before Descartes named the "I" as an indivisible baseline, Gautama Buddha ran a similar reduction on human consciousness and reached the opposite conclusion.

Where Descartes found a solid "I," the Buddha found a label. What we call a person or a self is a convenient name for a constantly shifting collection of five physical and mental heaps, the Five Aggregates (Skandhas/Khandhas):

1. Form (Rūpa): the body, the sense organs, and physical matter made of basic elements.
2. Feeling (Vedanā): the immediate tone of experience, whether pleasant, unpleasant, or neutral.
3. Perception (Saṃjñā): recognizing, labeling, and categorizing what the senses pick up.
4. Mental formations (Saṃskāra): volitional impulses, habits, intentional actions, and karmic conditioning.
5. Consciousness (Vijñāna): the awareness that cognizes objects across the sense spheres.

[ Form ] [ Feeling ] [ Perception ] [ Formations ] [ Consciousness ]

In the Maha-punnama Sutta, the Buddha examines each aggregate in turn: Is form constant or inconstant? Inconstant. Is what is inconstant easeful or stressful? Stressful. Is it fitting to regard what is inconstant and subject to change as 'This is mine, this is my self, this is what I am'?

Go through every layer of body and mind this way and none of the aggregates turns out to be permanent, independent, or self-contained. Even consciousness arises in dependence on sense organs and their objects; it isn't an enduring subject sitting underneath everything. The self is emergent, the way "chariot" is a conventional name for an assembly of wheels, axles, and frame.

Nāgārjuna and emptiness: why ultimate reality has no first principle

Western reductionism looks for an indivisible building block to stand on: atoms, logical axioms, fundamental substances. Nāgārjuna, founder of the Madhyamaka school, went after foundationalism itself.

His target was svabhāva, the idea that phenomena have an intrinsic, independent essence. In his major work, the Mūlamadhyamakakārikā, he argued that nothing exists independently, and he equated emptiness (Śūnyatā) with dependent origination (Pratītyasamutpāda):

$\text{Emptiness }(\text{Śūnyatā})\equiv \text{Dependent Origination }(\text{Pratītyasamutpāda})$

Reduce any object, cause, or concept to its constituents and you never reach a solid first principle or static building block. What you find is a web of relationships, each depending on the others.

Buddhist philosophy reconciles the two views with the Two Truths doctrine (Satyadvaya):

Living with both

We don't have to choose between Cartesian first principles and Buddhist emptiness. The skill is knowing which one applies to which part of life.

When you're designing rockets, crafting public policy, working through a hard strategic problem, or navigating social systems, use first principles. Strip away false analogies, build upward from verified facts, and act as an intentional, responsible subject.

When you're caught in anxiety, defensiveness, fear of failure, or grief over impermanence, use the aggregates and emptiness. Take the "I" apart. The ego that feels attacked or stressed is a temporary cluster of changing sensations, perceptions, and mental formations, with no enduring core.

The aim is to build a functional, even brilliant, world with first principles while staying grounded in the calm awareness that the builder is, pleasantly, empty.
