“too many people, so many mass executions of the elderly and infirm make sense… if the brain discards unused neurons, why shold socieity [sic] keep their equivalent”

“I looked up the statistics, black kids in the US have slower cognitive development”
Joscha Bach (born 1973) wikiquote, CC BY-SA 4.0 source
“Attempts in psychology at overarching theories of the mind have been all but shattered by the influence of behaviorism, and where cognitive psychology has sprung up in its tracks, it rarely acknowledges that there is something as "intelligence per se", as opposed to the individual performance of a group of subjects in an isolated set of experiments.”

“AI’s gradual demotion from a science of the mind to the nerdy playpen of engineering was accompanied not by utterances of disappointment, but by a chorus of glee, uniting those wary of human technological hubris with the same factions of society that used to oppose evolutionary theory or materialistic monism...”

“[W]e are in need of functionalist architectures. That is, we need to make explicit what entities we are going to research, what constitutes these entities conceptually, and how we may capture these concepts.”

“Early AI systems tended to constrain themselves to micro-domains that could be sufficiently described using simple ontologies and binary predicate logics, or restricted themselves to hand-coded ontologies altogether. ...AI systems will probably have to be perceptual symbol systems, as opposed to amodal symbol systems...”

“For all practical purposes, the universe is a pattern generator, and the mind "makes sense" of these patterns by encoding them according to the regularities it can find. Thus, the representation of a concept in an intelligent system is not a pointer to a "thing in reality", but a set of hierarchical constraints over (for instance perceptual) data.”

“[T]he quality of a world model eventually does not amount to how "truly" it depicts "reality", but how adequately it encodes the (sensory) patterns.”

“Robots are... not going to be the singular route to achieving AGI, and successfully building robots that are performing well in a physical environment does not necessarily engender the solution of the problems of AGI. Whether robotics or virtual agents will be first to succeed in the quest of achieving AGI remains an open question.”

“General intelligence is not only the ability to reach a given goal (and usually, there is some very specialized, but non-intelligent way to reach a singular fixed goal, such as winning a game of chess), but includes the setting of novel goals, and most important of all, about exploration. ...[A]n environment with fixed tasks, scaled by an agent with pre-defined goals is not going to make a good benchmark problem for AGI.”

“[M]otivation... does not arise from intelligence itself, but from a motivational system underlying all directed behavior. ...[T]here is no reason that could let us take behavioral tendencies such as self-preservation, energy conservation, altruistic behavior for granted—they... have... to be designed [including by evolutionary methods] into the system...”

“Because a naked ontological dualism between mind and body/world is notoriously hard to defend, it is sometimes covered up by wedging the popular notion of emergence into the "explanatory gap"... "strong emergence" is basically an anti-AI proposal.”

“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.”

“[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.”

“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.”

“[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 ...”

“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 .”

“Behaviorism... in the form of ... not only neglected the nature of mental entities as an object of inquiry, but denied their existence...”
Joscha Bach (born 1973) wikiquote, CC BY-SA 4.0 source
“[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...”

“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 ...”

“What's the best algorithm that you should be using to fix your world model? ...This question ...has been answered for the first time by in the 1960s. He discovered an algorithm that you can apply when you've discovered that you're a robot and all you've got is data. What is the world like? ...[H]is algorithm is... a combination of Bayesian Reasoning, Induction and Occam's Razor. ...[W]e can mathematically prove that we cannot do better than Solomonoff Induction. Unfortunately, Solomonoff Induction is not quite computable.”
Joscha Bach (born 1973) wikiquote, CC BY-SA 4.0 source
“[E]verything that we're going to do is some approximation of Solomonoff Induction. ...[O]ur concepts cannot really refer to facts in the world out there. We do not get the truth by referring to stuff out there in the world. We get meaning by suitably encoding the patterns in our systemic interface.”

“If you take the activation at different levels of these networks and you... enhance this activation a little... you get stuff that looks very psychadelic, which might be similar to what happens if you put certain illegal substances into people and enhance the activity on certain layers of their visual processing.”

“[O]ur best bet is not just to have a single classification with filtering. ...[I]nstead... take the low level of input and get a whole universe of features that is interrelated. ...[W]e have different levels of determinations. At the lowest level we have percepts. At a slightly higher level we have simulations, and on an even higher level we have a concept landscape.”

“[C]ausal models can be weakly deterministic, basically associative models, which tell you if this state [S1] happens, it is quite probable that this one [S2] comes afterwards. Or you can get to a strongly determined model... one which tells you, if you are in this state [S1], and this condition [c1] is met, you're going to go exactly in this state [S2]. If this state is not met, or a different condition [c2] is met, you go into this state [S3]. And this is what we call an algorithm. Now you're in the domain of computation.”

“Computation is different. Computation can exist. It starts with an initial state, and then you have a transition function. You do the work. You apply the transition function [and] you get into the next state. Computation is always finite.”

“Mathematics is the kingdom of specification and computation is the kingdom of implementation. It's very important to understand this difference.”
Joscha Bach (born 1973) wikiquote, CC BY-SA 4.0 source
“All our access to mathematics... is because we do computation. We can understand mathematics because our brain can compute some part of mathematics, very very little of it and to a very constrained complexity, but enough so we can map some of the infinite complexity and noncomputability of mathematics into computational patterns which we can explore.”

“[W]e saw that mental representation is about percepts, mental simulations, conceptual representations... [C]onceptual representations give us concept spaces, and... these concept spaces... give us an interface for our mental representations we can use to address and manipulate them, and we can share them in cultures. [T]hese concepts are compositional. We can put them together to create new concepts. ...[T]hey can be described using higher dimensional vector spaces. They [vectors] don't do mental simulation and prediction, and so on, but we can capture regularity in our concepts with them.”
