The Logical Necessity of a Substrateless World

Conclusion: The Freedom of a Substrateless World

The journey from Part I through Part V establishes a single, unified vision of reality:

  • Part I: Intrinsic nature cannot be coherently posited; phenomena are designated in dependence on conditions, free from the eight metaphysical extremes.

  • Part II: Entities and relations are designated together without hierarchy, collapsing two-tiered ontologies without installing a single level in their place; the two truths are two aspects of one appearance, and absolute nothingness, like substance, cannot be coherently posited.

  • Part III: Subject and object co-arise non-dually, reframing consciousness, states of awareness, and temporal continuity as conventional designations, with no invariant bearer and no ultimately real arising or ceasing.

  • Part IV: Mind, perception, and world co-arise enactively, dissolving the Cartesian split between internal containers and external realities.

  • Part V: Boundaries, functions and scientific laws are designated within frameworks and prove reliable in use, without requiring ontological solidity; science, down to the quantum level, can be read as refining designations rather than uncovering a substrate—a reading compatible with physics, not one physics compels.

By relinquishing the substantialist search for fixed foundations, we discover that vivid appearance does not imply ontological solidity. The eight metaphysical extremes (arising and ceasing, permanence and annihilation, coming and going, identity and difference) fall together because their common substantialist premise was never established to begin with.

Reality is neither a collection of isolated, rigid objects nor an empty illusion. Nor is it a field of interdependence standing in their place: dependence, too, is empty, designated only in dependence. What remains is not a final picture of reality but freedom from needing one—appearances vivid and functional, and nothing found beneath them, not even emptiness.

What Has Not Been Claimed

It may help, at the end, to say plainly what this book has not argued. It has not argued that nothing exists, or that the world is unreal. The ice is cold and the chariot carries passengers. It has not argued that relation, process, structure, experience or awareness is what reality is really made of; each of these candidates was examined and found to be designated, like everything else. It has not argued that emptiness is a hidden nature behind things, a void beneath them or a fullness within them. And it has not argued for a view to be held in place of other views. The negation has been non-implicative throughout: it removes inherent existence and puts nothing in its place.

This is why the argument can be a logical necessity without becoming a dogma. It does not say what the world is. It shows that every proposal of something standing on its own undermines itself, because the proposal already picks that something out by contrast and designation. Dependent arising has been used only to demonstrate emptiness, never as a new ground; and emptiness has been offered only as the absence of what was never there, not as something to believe in. Those who make emptiness into a view, Nāgārjuna warned, are incurable (MMK 13.8). The book has tried to leave its reader with no view in need of a cure.

Freedom, Concretely

The title of this conclusion speaks of freedom, and it is worth asking what that freedom is, since the analysis takes nothing out of the world. It is freedom from a particular weight: the felt solidity that makes each appearance seem final. An insult seems to sit in the words themselves, so it lodges and repeats. A reputation seems simply to be mine, so it must be defended. A loss seems to be the annihilation of something that was really there, so it seems to leave a hole in the world. In each case the suffering lies not in the appearance but in the reading of it as standing on its own.

Seen as designated, these appearances do not become trivial. The insult still hurts, the reputation still matters, the loss is still a loss, and the empty chair is still at the table. What changes is their grip. An appearance known to depend on conditions can be met, worked with and changed, because nothing in it is fixed. For whom emptiness is possible, Nāgārjuna says, everything is possible (MMK 24.14). Part V made this claim about function; here it is a claim about living. A chariot is repaired and a science revised; in the same way, with nothing fixed to obstruct it, a habit loosens, a grievance ends, a person changes.

There is freedom, too, for inquiry. Questions that seemed to demand a ground—why there is something rather than nothing, how matter gives rise to mind, what the world is ultimately made of—need not be abandoned, but they can be asked differently. They become questions about frameworks and their uses, about what holds up under further experience, rather than searches for a bottom that is not there.

A Way to Test It

This book has asked to be tested in experience as well as followed in argument, and it can end with a way to do so. Take any ordinary thing within reach—a cup, a pen, the phone. First, notice how it appears: its colour and weight, its temperature, the way it offers itself to the hand. Nothing in what follows asks you to see less of this.

Then look for it. Is the cup its colour, its handle, its clay, its shape? Is it in your seeing, or in the word 'cup', or apart from both? Go slowly, and notice that each place you look yields more appearance and no cup standing behind it. Then notice the seeing-as: that the cup was never seen first as neutral shapes and then named, but met as a cup from the start, the designation already in the vividness. Longer versions of this exercise, worked through a mountain, a flower and space, are given in The Transition from Anatta to Emptiness.

Finally, put the analysis down and simply use the cup. Drink from it. The point of the exercise is not to arrive at a feeling of emptiness, which would be one more thing to hold, but to notice that nothing was lost in the looking. The cup works exactly as before. What may have changed, a little, is the weight with which it was held—and that, multiplied across a life, is what this book has meant by freedom.

The Taste

And yet a view that has refused every ground does not end in loss. Its taste, in real time, is surprisingly positive. Pick up the ice again, or the phone: nothing has been taken away but the sense of a thing standing behind the appearance and of someone standing apart from it. What remains is appearance, vivid and unowned, exactly where it is—not a final picture of reality, and not a hidden fullness beneath it, but the ordinary world met without reification.

Return, finally, to the whirlpool with which the book began. It still turns in the river. The leaves still spin in it, and a child can still point to it and time it with a watch. Not one drop of the water stays, and nothing is found when the whirlpool is sought apart from the water, the bank and the one who watches. Nothing has been taken from it by the analysis, and nothing has been added. It is what everything has been all along: vivid, functional and designated. Seeing that is the freedom.
