The philosophical argument for “no-self” (Buddhism’s Anātman/Anattā) posits that there is no permanent, unchanging, or independent self, soul, or ego. Instead, what we call the “self” is a fleeting collection of constantly shifting physical and mental processes—form, sensation, perception, volition, and consciousness—that are dependent upon causes and conditions.
Key Arguments for No-Self
The Argument from Impermanence: Everything that constitutes a person (the “five skandhas” or aggregates) is impermanent and constantly changing. A permanent self cannot be composed of, or found within, these fleeting elements.
The Chariot Metaphor (Dependent Designation): From The Questions of King Milinda, this argument highlights that a “chariot” is just a label for a collection of parts (wheels, axle, axle-tree). There is no chariot independent of its parts. Similarly, “I” or “Nagasena” is a conventional designation for the mental and physical parts, but no permanent entity exists behind them.
Lack of Control/Ownership: If a self existed, one should be able to command it (e.g., “let my body not be old” or “let my mind be calm”). Because we cannot fully control our feelings, thoughts, or physical aging, these components cannot be a self that we own.
The Bundle Theory (Humean View): David Hume, a Western philosopher, similarly observed that when he looked inside himself, he only found specific perceptions (heat, light, love, hatred, pain) but never a unified “self” to which they belonged. He described the self as a “bundle of perceptions”. Philosophy Now +4
The Illusion and Function of Self
The “self” is not considered non-existent, but rather empty of inherent existence. It exists conventionally—as a convenient designation for managing daily life—but not ultimately. Believing in a solid self causes attachment and suffering (suffering arises from trying to protect a permanent ego that doesn’t exist). Understanding no-self is intended to reduce this craving and suffering.
I’m just wondering how people who don’t believe in the existence of the self life and operate in the world, because much of our daily life is structured around there being a self or other, especially a lot of our media.
