We live in an age saturated with information.
Genes are said to contain it. Brains are said to process it. Communication systems are said to transmit it. Physics, biology, linguistics, computer science, and cognitive science all speak fluently in its vocabulary.
It has become one of the most universal explanatory terms in contemporary science.
And yet it is rarely asked what kind of thing information actually is.
At first glance, the answer seems obvious.
Information is what is carried in signals, encoded in DNA, stored in memory, transmitted across networks, and extracted from data.
But each of these descriptions already assumes something that deserves closer attention.
To say that information is carried is to invoke a physical metaphor.
To say that it is encoded is to assume a code that precedes interpretation.
To say that it is stored is to imagine a substance persisting in a container.
In each case, information is treated as though it were a kind of invisible stuff distributed across different substrates.
This is where the difficulty begins.
Consider a simple example.
A string of marks on a page:
1011001
Does it contain information?
The answer seems to be yes.
But now ask: information about what?
About binary arithmetic? A genetic sequence? A computer instruction? A symbolic encoding system? Without a system of interpretation, the marks remain simply marks.
Nothing intrinsic to them determines what they mean.
The same pattern can function as different information within different relational contexts.
What changes is not the pattern itself.
What changes is the construal.
This suggests something important.
Information is not a property of a physical configuration considered in isolation.
It is a relational effect that emerges when a configuration is taken up within a system of interpretation, distinction, and use.
A genome does not contain information in the way a bottle contains liquid.
A DNA sequence participates in a complex developmental system that has been shaped through evolutionary history. Within that system, certain variations reliably correlate with certain developmental outcomes. We describe this stability using informational language.
But the language describes a relation.
It does not name a substance.
The same is true in neuroscience.
Neural signals are said to encode sensory information, motor commands, or cognitive content. Yet these signals acquire their informational character only within the interpretive framework that relates neural activity to behavioural, environmental, and experimental conditions.
Outside that framework, they are simply electrochemical events.
Not messages.
Not representations.
Not packets of meaning.
Likewise in physics, where entropy and information are often treated as interchangeable quantities. Yet even here, information depends upon a partitioning of the world into states, distinctions, and coarse-grained descriptions. Change the partition, and the “amount of information” changes with it.
Across all these domains, a consistent pattern emerges.
Information appears whenever a system of distinctions is imposed upon a domain of variation.
It is not a thing in the world.
It is a way of organising the world.
This does not make information illusory.
But it does make it dependent.
Dependent on systems that distinguish, interpret, and act.
Dependent on the relational structures within which patterns become meaningful.
From this perspective, information is not fundamental.
It is derivative.
It arises when a difference is taken up within a system capable of responding to that difference.
A signal is not information in itself.
It becomes information when it is actualised as such within a relational field of interpretation and use.
This is why the idea that genes “contain information” or brains “process information” is so powerful—and so misleading.
It encourages us to imagine that information is already fully formed inside a physical substrate, waiting to be decoded.
But nothing in the substrate guarantees this.
DNA does not interpret itself.
Neurons do not read themselves.
Paper does not understand writing.
Information appears only when construal occurs.
This is the crucial shift.
Not from physical to mental.
But from substance to relation.
From contained meaning to actualised distinction.
From thing-like information to event-like information.
Seen this way, information does not exist as a fundamental ingredient of reality.
What exists are structured differences within physical systems, and the relational practices through which those differences are taken up as meaningful, functional, or significant.
Information is the name we give to that uptake.
It is not what the world is made of.
It is how certain differences become available within it.
And once this is recognised, the familiar picture reverses.
We do not live in a world made of information.
We live in a world in which information occasionally happens.
