"[...] according to the quantum theory, randomness is a basic trait of reality, whereas in classical physics it is a derivative property, though an equally objective one. Note, however, that this conclusion follows only under the realist interpretation of probability as the measure of possibility. If, by contrast, one adopts the subjectivist or Bayesian conception of probability as the measure of subjective uncertainty, then randomness is only in the eye of the beholder." (Mario Bunge, "Matter and Mind: A Philosophical Inquiry", 2010)
"Our mental model governs what we see, how we think about things and how we act, but is this just an individual phenomenon, or can whole communities and professions share a common mental model, a shared view of reality? […] What is beyond doubt is that all professions have their own vocabularies, lexicons, tools and techniques. These models, techniques and ways of analysing things are not value-free; they represent a way of seeing the world. When we select and use them we are subconsciously buying into that way of thinking and, inevitably, we are also reinforcing our own mental model of cause and effect. We tend to expend significant effort in understanding the inner workings of a new tool or practice, but we give scant attention to the thought paradigm that underpins it." (Robina Chatham & Brian Sutton, "Changing the IT Leader’s Mindset", 2010)
"What is the basis of this interest in beauty? Is it the same in both mathematics and science? Is it rational, in either case, to expect or demand that the products of the discipline satisfy such a criterion? Is there an underlying assumption that the proper business of mathematics and science is to discover what can be discovered about reality and that truth - mathematical and physical - when seen as clearly as possible, must be beautiful? If the demand for beauty stems from some such assumption, is the assumption itself an article of blind faith? If such an assumption is not its basis, what is?" (Raymond S Nickerson, "Mathematical Reasoning: Patterns, Problems, Conjectures, and Proofs", 2010)
"With each theory or model, our concepts of reality and of the fundamental constituents of the universe have changed." (Stephen Hawking & Leonard Mlodinow, "The Grand Design", 2010)
"It is ironic but true: the one reality science cannot reduce is the only reality we will ever know. This is why we need art. By expressing our actual experience, the artist reminds us that our science is incomplete, that no map of matter will ever explain the immateriality of our consciousness." (Jonah Lehrer, "Proust Was a Neuroscientist", 2011)
"Mental models and rules are intimately intertwined, since the models often suggest clear rules for societies to follow. Religions are more than theories; they are prescriptive moral codes that seek to enforce rules on their followers. They, like the rules they enjoin, are invested with considerable emotional meaning and therefore are believed for intrinsic reasons and not simply because they are accurate or useful. While religious beliefs cannot be verified, they are also difficult to falsify. All of this reinforces the fundamental conservatism of human societies, because mental models of reality once adopted are hard to change in the light of new evidence that they are not working." (Francis Fukuyama, "The Origins of Political Order", 2011)
"There are actually two sides to the success of mathematics in explaining the world around us (a success that Wigner dubbed ‘the unreasonable effectiveness of mathematics’), one more astonishing than the other. First, there is an aspect one might call ‘active’. When physicists wander through nature’s labyrinth, they light their way by mathematics - the tools they use and develop, the models they construct, and the explanations they conjure are all mathematical in nature. This, on the face of it, is a miracle in itself. […] But there is also a ‘passive’ side to the mysterious effectiveness of mathematics, and it is so surprising that the 'active' aspect pales by comparison. Concepts and relations explored by mathematicians only for pure reasons - with absolutely no application in mind - turn out decades (or sometimes centuries) later to be the unexpected solutions to problems grounded in physical reality!" (Mario Livio, "Is God a Mathematician?", 2011)
"To think one needs to use a mental model, but mental models are only an abstraction of reality and at best an oversimplification. Making them explicit is the only chance one has to learn and improve them." (Jamshid Gharajedaghi, "Systems Thinking: Managing Chaos and Complexity", 2011)
"Equations have hidden powers. They reveal the innermost secrets of nature. […] The power of equations lies in the philosophically difficult correspondence between mathematics, a collective creation of human minds, and an external physical reality. Equations model deep patterns in the outside world. By learning to value equations, and to read the stories they tell, we can uncover vital features of the world around us." (Ian Stewart, "In Pursuit of the Unknown", 2012)
"Simply put, a conceptual model is a simplified representation of reality, devised for a certain purpose and seen from a certain point of view." (David W Emble & Bernhard Thalheim, "Handbook of Conceptual Modeling", 2012)
"Complex systems defy intuitive solutions. Even a third-order, linear differential equation is unsolvable by inspection. Yet, important situations in management, economics, medicine, and social behavior usually lose reality if simplified to less than fifth-order nonlinear dynamic systems. Attempts to deal with nonlinear dynamic systems using ordinary processes of description and debate lead to internal inconsistencies. Underlying assumptions may have been left unclear and contradictory, and mental models are often logically incomplete. Resulting behavior is likely to be contrary to that implied by the assumptions being made about' underlying system structure and governing policies." (Jay W Forrester, "Modeling for What Purpose?", The Systems Thinker Vol. 24 (2), 2013)
"Complexity has the propensity to overload systems, making the relevance of a particular piece of information not statistically significant. And when an array of mind-numbing factors is added into the equation, theory and models rarely conform to reality." (Lawrence K Samuels, "Defense of Chaos: The Chaology of Politics, Economics and Human Action", 2013)
"It's pretty much a fact that our entire universe is a mental construct. We don't actually deal with reality directly. We simply compose a picture of reality from what's going on in our retinas, in the timpani of our ears, and in our nerve endings." (Alan Moore, The Believer No. 99, [interview] 2013)
"Models do not only describe reality, they are also instruments for exploring reality. They are not only involved in the integration of known data, but also in the discovery of new data." (Andreas Bartels, "The Standard Model of Cosmology as a Tool for Interpretation and Discovery", 2013)
"Paradoxes often arise because theory routinely refuses to be subordinate to reality." (Lawrence K Samuels, "Defense of Chaos: The Chaology of Politics, Economics and Human Action", 2013)
"In general, when building statistical models, we must not forget that the aim is to understand something about the real world. Or predict, choose an action, make a decision, summarize evidence, and so on, but always about the real world, not an abstract mathematical world: our models are not the reality - a point well made by George Box in his oft-cited remark that "all models are wrong, but some are useful". (David Hand, "Wonderful examples, but let's not close our eyes", Statistical Science 29, 2014)
"It is always easier to deny reality than to allow our worldview to be shattered […]" (Naomi Klein, "This Changes Everything", 2014)
"Math is a way to describe reality and figure out how the world works, a universal language that has become the gold standard of truth. In our world, increasingly driven by science and technology, mathematics is becoming, ever more, the source of power, wealth, and progress. Hence those who are fluent in this new language will be on the cutting edge of progress." (Edward Frenkel, "Love and Math", 2014)
"One of the remarkable features of these complex systems created by replicator dynamics is that infinitesimal differences in starting positions create vastly different patterns. This sensitive dependence on initial conditions is often called the butterfly-effect aspect of complex systems - small changes in the replicator dynamics or in the starting point can lead to enormous differences in outcome, and they change one’s view of how robust the current reality is. If it is complex, one small change could have led to a reality that is quite different." (David Colander & Roland Kupers, "Complexity and the art of public policy : solving society’s problems from the bottom up", 2014)
"The lesson for a world of Big Data is that in an environment with excessive information, people may gravitate toward answers that simplify reality rather than embrace the sheer complexity of it." (Zachary Karabell, "The Leading Indicators: A short history of the numbers that rule our world", 2014)
"What is consciousness? Our brain simulates reality. So, our everyday experiences are a form of dreaming, which is to say, they are mental models, simulations, not the things they appear to be." (Stephen LaBerge, "Losi in Lucidity", 2014)
"A worldview is a commitment, a fundamental orientation of the heart, that can be expressed as a story or in a set of presuppositions (assumptions which may be true, partially true or entirely false) which we hold (consciously or subconsciously, consistently or inconsistently) about the basic constitution of reality, and that provides the foundations on which we live and more and have our being." (James W Sire, "Naming the Elephant: Worldview as a Concept", 2015)
"Fuzzy thinking can never be proven wrong. And only when we are proven wrong so clearly that we can no longer deny it to ourselves will we adjust our mental models of the world - producing a clearer picture of reality. Forecast, measure, revise: it is the surest path to seeing better." (Philip E Tetlock, "Superforecasting: The Art and Science of Prediction", 2015)
"Religion claims to help us understand things about the universe, but, unlike science has no way to test or verify its claims. Both science and religion compete to understand reality, but only science has the method to verify its findings, while religion merely buttresses emotional and epistemic commitments made in advance, commitments impervious to evidence." (Jerry Coyne, 2015)
"Science, at its core, is simply a method of practical logic that tests hypotheses against experience. Scientism, by contrast, is the worldview and value system that insists that the questions the scientific method can answer are the most important questions human beings can ask, and that the picture of the world yielded by science is a better approximation to reality than any other." (John M Greer, "After Progress: Reason and Religion at the End of the Industrial Age", 2015)
"The intent of these representations is to capture the relevant characteristics of reality, which may overlap but are not identical in each case. The engineer has to ascertain what those are, and then incorporate appropriate assumptions and simplifications accordingly. Two common strategies are abstraction, which involves neglecting certain aspects of reality in order to gain a better understanding of the remaining aspects; and idealization, which involves replacing a complicated and/or complex aspect of reality with a simplified version." (Jon A Schmidt, "Representation and Reality", Structure [magazine], 2015)
"A mathematical model is never a completely accurate representation of a physical situation - it is an idealization. A good model simplifies reality enough to permit mathematical calculations but is accurate enough to provide valuable conclusions. It is important to realize the limitations of the model. In the end, Mother Nature has the final say." (James Stewart, "Calculus: Early Transcedentals" 8th Ed., 2016)
"A mental model is not necessarily founded on facts or complete understanding of reality. Let's be honest, most of our mental models are flawed in many ways, and that's perfectly normal. They work because they are fast and simple and not because they are a complete representation of the reality. […] The most important thing about a person's mental model is that it's simplified and very limited compared to what it models." (Peter W Szabo, "User Experience Mapping", 2017)
"A worldview is simply someone's relatively organized understanding of what the world is actually like. [...] Worldviews have four elements that help us understand how a person's story fits together: creation, fall, redemption, and restoration. ‘Creation’ tells us how things began, where everything came from (including us), the reason for our origins, and what ultimate reality is like. ‘Fall’ describes the problem (since we all know something has gone wrong with the world). ‘Redemption’ gives us the solution, the way to fix what went wrong. ‘Restoration’ describes what the world would look like once the repair begins to take place." (Greg Koukl, [interview with Jonathan Petersen], 2017)
"A theory is nothing but a tool to know the reality. If a theory contradicts reality, it must be discarded at the earliest." (Awdhesh Singh, "Myths are Real, Reality is a Myth", 2018)
