The Brahmajala Sutta identifies eternalism and materialism as two of sixty-two wrong views, showing why both extremes fail to account for dependent origination.
The Brahmajala Sutta is the first discourse in the Pali Canon's Digha Nikaya (Long Discourses). The Buddha teaches it to his monks after overhearing wandering ascetics praise and criticize him. Rather than defend himself, he uses the occasion to map out the full landscape of wrong views that trap sentient beings in suffering. The sutta's name refers to Brahma's net, a metaphor suggesting how interconnected wrong views are—pull one thread and the entire net of delusion becomes visible.
The sutta catalogs sixty-two distinct wrong views, organized into several categories based on their logical structure and metaphysical assumptions. This systematic approach helps practitioners recognize subtle philosophical errors they might otherwise adopt unknowingly.
Eternalism, called sassata-ditthi in Pali, is the belief that some aspect of existence is permanent, unchanging, or eternal. The Brahmajala Sutta identifies multiple eternalist positions. Some teachers claim the soul and world are eternal. Others claim the soul is eternal but the world finite, or vice versa. Still others propose partial eternalism—that only certain aspects of reality persist forever while others are temporary.
The Buddha's critique of eternalism rests on the fundamental insight of impermanence (anicca). Everything conditioned by causes and conditions must change. A permanent, unchanging soul or essence cannot logically coexist with the observable fact that all aggregates of body, feeling, perception, mental formations, and consciousness are in constant flux. Eternalist views arise from clinging to the delusion of a fixed self, which is itself a misunderstanding of how dependent origination actually functions.
Materialism, or uccheda-ditthi (annihilationism), holds the opposite extreme: that everything ceases completely at death, that consciousness depends entirely on matter, and that there is no continuity beyond physical dissolution. Some materialist teachers in the Buddha's time taught that the four elements alone are real and that moral actions have no consequences. Others claimed a person is simply a combination of physical parts with no unified consciousness.
The Brahmajala Sutta addresses materialism as a failure to recognize how intention and karma operate across time. Even if one rejects a permanent soul, the Buddhist analysis shows that consciousness arises in dependence on conditions, and mental action (intention) produces results that manifest in future experience. Materialism's error is assuming that the absence of a permanent self means the absence of causal continuity altogether—a logical leap that ignores the actual mechanics of dependent origination.
The deeper teaching underlying the Brahmajala Sutta's rejection of both eternalism and materialism is dependent origination (paticca-samuppada). This principle states that phenomena arise in dependence on conditions and cease when conditions dissolve. It describes a middle way that avoids both extremes.
Eternalism assumes something must persist unchanged to explain continuity. Materialism assumes nothing persists, making continuity impossible to explain. But dependent origination shows how phenomena can be genuinely impermanent while still producing coherent causal sequences. Consciousness in one moment conditions consciousness in the next; actions leave traces that ripen as results. This is neither permanent essence nor absolute annihilation.
Understanding how the Brahmajala Sutta addresses these extremes matters not as mere philosophy but as a guide to liberation. Clinging to eternalism sustains the delusion of a permanent self that needs protecting and perpetuating. Clinging to materialism can undermine ethical practice by denying karmic consequences. The sutta implicitly teaches that genuine freedom comes through recognizing the middle path: phenomena are real and consequential but not fixed or self-subsisting.
Different Buddhist traditions emphasize this teaching in varying ways. Theravada commentaries tend to treat the sutta's analysis as foundational to right view. Mahayana traditions sometimes reframe eternalism and materialism as failures to understand emptiness (sunyata), which points beyond both permanence and annihilation. Yet all traditions recognize the Brahmajala Sutta as essential instruction for avoiding the philosophical traps that reinforce suffering.
