sciences. There is not yet a strong consensus about its nature. However, many (but not all) explanations that rely on representations can in turn be explained by a family of theories of representation that appeal to internal entities that: (i) stand in exploitable
relations to the world (e.g. correlation, correspondence), and (ii) interact in internal processes (algorithms); both (iii) in the service of performing some task or function.</span></div>
<div style="direction: ltr; margin: 0px;"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">We can also explain why things that afford this kind of explanation arise
systematically in nature. Very roughly, stabilising processes like natural selection and learning are a diachronic force for producing certain outcomes robustly, and one way to achieve that synchronically is to calculate over internal states bearing exploitable
relations to various features of the problem space. The most obvious cases are where representations are decoupled from immediate environmental input, but the same rationale, and the same explanatory scheme, is also present in simpler cases where no decoupling
is involved.</span></div>

makes sense of appeals to neural representation. There, the representational vehicles are patterns of activity in neural assemblies (or sometimes individual neurons); and computations take place between attractors or regions in neural activation spaces. Such
accounts are equally applicable to explaining the operation of deep neural networks.</span></div>

behavior. For the most part, representational behavior of the kind that we are all interested in (if we are honest) is what humans do – we can contemplate black holes, imagine non-existent architectures and worlds (think Narnia and Dune), and write abstracts
like this one. Representation is an explanandum – it is what must be present to do overt deliberative thought and understand things. Most intelligent behavior is non-representational, it does not need to be, survival can occur perfectly well without it: an
arctic fox does not worry about what ice is. It is easy to confuse these two kinds of behavior and the means to explain them. Naturalizing representation is for the most part the project to perpetuate this confusion. It is driven by the hope that some intelligent
animal behaviors are using representational capacities of the kind that humans undoubtedly have, and that these capacities can be dissected using the modern tools of neuroscience. Two of the terms used for these protorepresentations are cognitive maps and
internal models. The claim is that these are the foot in the door that will get us to the representations needed for full blown conceptual abstract thought. This stance is, in my view, misguided for several reasons that I will elucidate. Intelligence – competence
without comprehension – does not need representations. Overt representations are the substrate upon which comprehension operates but we do not have a theory for them yet.</span></div>
