Quote by Richard Dawkins

“[O]ur percept is an elaborate computer model in the brain, constructed on the basis of information coming from [the environment], but transformed in the head into a form in which that information can be used. Wavelength differences in the light out there become coded as 'colour' differences in the computer model in the head. Shape and other attributes are encoded in the same kind of way, encoded into a form that is convenient to handle. The sensation of seeing is, for us, very different from the sensation of hearing, but this cannot be directly due to the physical differences between light and sound. Both light and sound are, after all, translated by the respective sense organs into the same kind of nerve impulses. It is impossible to tell, from the physical attributes of a nerve impulse, whether it is conveying information about light, about sound or about smell. The reason the sensation of seeing is so different from the sensation of hearing and the sensation of smelling is that the brain finds it convenient to use different kinds of internal model of the visual world, the world of sound and the world of smell. It is because we internally use our visual information and our sound information in different ways and for different purposes that the sensations of seeing and hearing are so different. It is not directly because of the physical differences between light and sound.”

The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe without Design

Presenting a detailed examination of the mechanisms of evolution, the book argues that natural selection is the primary driver of biological diversity and complexity, and challenges the notion of a divine creator in the process. more

Richard Dawkins is a British ethologist, writer, and thinker, known for his contributions to evolutionary theory, particularly in the field of modern synthesis. He is widely recognized for his best-selling book 'The Selfish Gene', which explains the central role of genes in biological evolution. Dawkins has made significant impacts in the field of science communication and has sparked widespread discussions about human behavior and morality. more

“Children discover and verify their theories in quite the same way that scientists do: through experimentation. They manipulate the world and discover regularities of causation from those manipulations. Why do they do it? The discovery of regularities comes with a pleasurable burst of insight, which all of us, but especially children and scientists, continuously long for like bonbons or opium.”

“[T]he form that an animal's subjective experience takes will be a property of the internal computer model. That model will be designed, in evolution, for its suitability for useful internal representation, irrespective of the physical stimuli that come to it from outside. Bats and we need the same kind of internal model for representing the position of objects in three-dimensional space. The fact that bats construct their internal model with the aid of echoes, while we construct ours with the aid of light, is irrelevant.”

“Truly to realize the ambitions of a science of mind does not solely involve learning about such issues as how we know, perceive and solve problems; it involves finding out tow hat extent the world outside us is knowable by us, and indeed prescribing the limits of inquiry for disciplines like Physics which claim to afford knowledge of the external physical world.”

“Once we have isolated the computational and neurological correlates of access-consciousness, there is nothing left to explain. It's just irrational to insist that sentience remains unexplained after all the manifestations of sentience have been accounted for, just because the computations don't have anything sentient in them. It's like insisting that wetness remains unexplained even after all the manifestations of wetness have been accounted for, because moving molecules aren't wet.”

“A synthesis—an abstraction, chunk, or gist idea—is a neural pattern. Good chunks form neural patterns that resonate, not only within the subject we’re working in, but with other subjects and areas of our lives. The abstraction helps you transfer ideas from one area to another. That’s why great art, poetry, music, and literature can be so compelling. When we grasp the chunk, it takes on a new life in our own minds—we form ideas that enhance and enlighten the neural patterns we already possess, allowing us to more readily see and develop other related patterns. Once we have created a chunk as a neural pattern, we can more easily pass that chunked pattern to others, as Cajal and other great artists, poets, scientists, and writers have done for millennia, Once other people grasp that chunk, not only can they use it, but also they can more easily create similar chunks that apply to other areas in their lives—an important part of the creative process.”

“To deny the truth of our own experience in the scientific study of ourselves is not only unsatisfactory; it is to render the scientific study of ourselves without a subject matter. But to suppose that science cannot contribute to an understanding of our experience may be to abandon, within the modern context, the task of self-understanding. Experience and scientific understanding are like two legs without which we cannot walk. We can phrase this very same idea in positive terms: it is only by having a sense of common ground between cognitive science and human experience that our understanding of cognition can be more complete and reach a satisfying level. We thus propose a constructive task: to enlarge the horizon of cognitive science to include the broader panorama of human, lived experience in a disciplined, transformative analysis.”

“Characteristics of System 1: • generates impressions, feelings, and inclinations; when endorsed by System 2 these become beliefs, attitudes, and intentions • operates automatically and quickly, with little or no effort, and no sense of voluntary control • can be programmed by System 2 to mobilize attention when a particular pattern is detected (search) • executes skilled responses and generates skilled intuitions, after adequate training • creates a coherent pattern of activated ideas in associative memory • links a sense of cognitive ease to illusions of truth, pleasant feelings, and reduced vigilance • distinguishes the surprising from the normal • infers and invents causes and intentions • neglects ambiguity and suppresses doubt • is biased to believe and confirm • exaggerates emotional consistency (halo effect) • focuses on existing evidence and ignores absent evidence (WYSIATI) • generates a limited set of basic assessments • represents sets by norms and prototypes, does not integrate • matches intensities across scales (e.g., size to loudness) • computes more than intended (mental shotgun) • sometimes substitutes an easier question for a difficult one (heuristics) • is more sensitive to changes than to states (prospect theory)* • overweights low probabilities* • shows diminishing sensitivity to quantity (psychophysics)* • responds more strongly to losses than to gains (loss aversion)* • frames decision problems narrowly, in isolation from one another*”
