Joscha Bach Quotes

To perceive means... to find order over patterns; these orderings are what we call objects. ...[I]t amounts to ...identification of these objects by their related patterns ...intuitively ...its features ...

Functional constructivism is based on... philosophical constructivism... that all knowledge about the world is based on... our systematic interface. ...We do not ...recognize ...objects of our environment; we construct them over the regularities ...at the system interface of our cognitive system.

[I]nfluences that lead to the study of... mental entities and structures... came from... s and cybernetics, and from formal linguistics. They fostered an understanding that mental activity amounts to ... that can be modeled as... an algorithm—working over states that encode representations.

Unlike physics, where previously unknown entities and mechanisms... are routinely postulated... and... evidence is sought in favor or against these... psychology shuns [this methodology]... Thus... cognitive psychology shows reluctance... to building unified theories of mental processes. ...Piaget's work ...might be one of the notable exceptions ...

[N]egligence of internal states of the mind makes it difficult to form conclusive theories of cognition, especially with regard to language... and consciousness, so radical behaviorism... lost its foothold. Yet, methodological behaviorism is still prevalent...

Behaviorism... in the form of ... not only neglected the nature of mental entities as an object of inquiry, but denied their existence...

Because there is no narrow, concise understanding of what constitutes mental activity and what is part of mental processes... cognition, the cognitive sciences and the related notions span a wide and convoluted terrain... most of [which] lies outside psychology... This methodological discrepancy can only be understood in the context of the recent .

[T]he relationship between cognition and neurobiological processes might be similar to the one between a car engine and locomotion. ...[A] car's locomotion is facilitated mainly by its engine, but the understanding of the engine does not aid much in finding out where the car goes. ...[T]he integration of... parts, the intentions of the driver and even the terrain might be more crucial ...

Our... cognitive architecture is based on a formal [psychological] theory... the PSI theory... [which] has been turned into a computational model... MicroPSI... partially implemented as a computer program.

Cognitive architectures are... Leibnizian machines... designed to bring forth the feats of cognition, and built to allow us to enter... examine them, and to watch their individual parts... pushing and pulling... thereby explaining how a mind works.

This book is an attempt to explain cognition—thought, perception, emotion, experience—in terms of a machine, that is, using a cognitive architecture.

[T]aking [the design of a cognitive architecture] to the AI laboratory... requires the theory not merely to be plausible, but... requires it to be fit for implementation, and delivers it to the... merciless battle of testing.

[T]he designer of a unified architecture is in a similar situation as the cartographers that set out to draw the first maps of the world, based on the reports of traders and explorers returning from expeditions into uncharted waters and journeys to unknown coasts.

[D]espite inevitable difficulties and methodological problems, the design of unified architectures modeling the breadth of mental capabilities in a single system is a crucial stage in understanding the human mind...

Symbolic reasoning falls short not only in modeling low level behaviors but is also difficult to ground into real world interactions and to scale upon dynamic environments... This has lead many... to abandon symbolic systems... and... focus on parallel distributed, entirely sub-symbolic approaches... well suited for many learning and control tasks, but difficult to apply [in] areas such as reasoning and language.
