This study explores the historical concept of ether within the framework of modern theoretical physics by deriving Maxwell’s equations that incorporate magnetic monopoles from the Navier-Cauchy equation with stress couples. We demonstrate that the elastomechanical interpretation of electromagnetism not only revitalizes the ether concept but also provides a coherent theoretical foundation for understanding electromagnetic phenomena. This interpretation reveals a significant link between mechanical properties and electromagnetic behaviors, for example, the charge of fundamental particles, such as electrons, is inherently connected to (...) rotational dynamics within the elastomechanical medium. Additionally, we introduce the magnetic monopole as a critical component of our framework, showing how it is associated with mass flux and volume changes in the medium, thus contributing to the dynamics of particle generation. Our findings highlight the profound interplay between elastodynamics, classical electromagnetism, and contemporary concepts in physics, paving the way for new epistemological perspectives. This research underscores the potential for integrating diverse physical theories to foster innovative developments in theoretical physics, challenging traditional views and inviting further exploration of the fundamental forces that govern the universe.

The model of quantised space is not popular because experimental physics is phenomenological based. So if we stop to focus on local phenomena we are forced to change the way we think about reality. Because in quantised space everything influences everything at exactly the same moment. Fortunately the electromagnetic dipole of a rest mass carrying particle shows the reliability of quantised space as an explanatory model.

In this short paper, we propose a special class of quantum systems with implicit quantum uncertainties without any probability structure followed by the dynamical behavior of the systems. When a system is deterministic or random, it does not capture the essence of freedom of choice (FOC), which is the ability to make decisions followed by one’s preferences, free from both deterministic and random outcomes. The proposed special class of quantum systems contains non-deterministic yet non-random outcomes, and so they open the (...) possibility of having FOC within the systems. We also examine examples of such a special class of quantum systems that do not violate the postulates of quantum mechanics. (shrink)

We revisit the concept of de Sitter (dS) ‘tachyonic’ scalar fields, characterized by discrete negative squared mass values, and assess their physical significance through a rigorous Wigner-inspired group-theoretical analysis. This perspective demonstrates that such fields, often misinterpreted as inherently unstable due to their mass parameter, are best understood within the framework of unitary irreducible representations (UIRs) of the dS group. The discrete mass spectrum arises naturally in this representation framework, offering profound insights into the interplay between dS relativity and quantum (...) field theory. Contrary to their misleading nomenclature, we argue that the ‘mass’ parameter associated with these fields lacks intrinsic physical relevance, challenging traditional assumptions that link it to physical instability. Instead, any perceived instability originates from mismanagement of the system’s inherent gauge invariance rather than the fields themselves. A proper treatment of this gauge symmetry, particularly through the Gupta–Bleuler formalism, restores the expected characteristics of these fields as free quantum entities in a highly symmetric spacetime. This study seeks to dispel misconceptions surrounding dS ‘tachyonic’ fields, underscoring the importance of precise terminology and robust theoretical tools in addressing their unique properties.

The fact that the “probability density” expression provided by the Klein–Gordon equation can take on negative values is usually seen as an obstacle to formulating a particle interpretation of quantum mechanics. Nevertheless, reconciling this expression with a particle ontology is quite possible once a careful distinction is drawn between the outcomes of measurements and the positions of particles between measurements. Following this path, however, points to the involvement of retrocausality, as proposed by various authors in other contexts.

Some experimental theories of quantum gravity, such as loop quantum gravity, propose a discrete or ``quantized'' structure for space-time at very small scales. These theories hypothesize that space-time is fundamentally made up of discrete units or ``atoms'' of space, in a similar way to how matter is fundamentally made up of discrete particles. In the context of space-time, the term ``atomic structure'' is used metaphorically to suggest a discrete or granular nature at extremely small scales. In Einstein's special theory of (...) relativity, there is a maximum limit of speed, beyond which no point of mass in an inertial reference frame can travel. In the following, I will demonstrate that in a given inertial reference frame, in addition to the existence of an upper limit velocity of the motion of a point of mass, there are also logical reasons to think that space and time have an atomic structure. The basic idea of this argument was suggested by Zeno's well-known aporias. (shrink)

Today, perovskite solar cells are introduced and used as a suitable alternative with high efficiency for silicon solar cells. The main problem of this type of cells until now has been mostly about their instability, because these materials that are used in perovskite solar cells are rapidly destroyed in reaction with air or their efficiency is greatly reduced. In this article, we increase the productivity to an acceptable amount and also increase its stability by using new high-quality synthesized materials and (...) also by changing the manufacturing method of perovskite solar cells. Using the hole transport layers (HTLs), in the inverse planar perovskite solar cell structure, the effect of two layers of poly (triarylamine)(PTAA) and poly (3, 4-ethylenedioxythiophene)(PEDOT): PSS as the bottom layer of the perovskite film on the morphology of the nanoparticles, the crystallinity of the perovskite layer and the photovoltaic parameters affecting the efficiency of the solar cell made in a single-step method were investigated. The result shows the PTAA layer has been very effective in controlling the morphology of the perovskite layer, so the efficiency reached to 23.9% while the maximum efficiency per solar cell based on PEDOT: PSS is 11.37%.

We introduce a new structure, the critical multi-cubic lattice. Notably the critical multi-cubic lattice is the first true generalization of the cubic lattice to higher dimensional spaces. We then introduce the notion of a homomorphism in the category of critical multi-cubic lattices, compute its automorphism group, and construct a Hilbert space over which we represent the group. With this unitary representation, we re-derive the generalized Pauli matrices common in quantum computation while also defining an algebraic framework for an infinite system (...) of qudits. We also briefly explore the critical multi-cubic lattice as a novel implication algebra serving as a logical framework for qudit gates. (shrink)

This short note addresses the criticisms recently proposed by Shan Gao against our article “On the Reality of the Quantum State Once Again: A No-Go Theorem for $$\psi$$ -Ontic Models” (Found. Phys. 54:14). The essay aims to respond to such objections and to show once again that the theorem proved in our paper is correct, and therefore true—contrary to Gao’s claims. Philosophical consequences of this fact are briefly discussed.

Instances of the law of large numbers are used to model many different physical systems. In this paper, I argue for a particular interpretation, of those instances of that law, which appeals to typicality. As I argue, the content of that law, when used to model physical systems, is that the probability of an event typically—rather than probably—approximates the frequency with which that event occurs.

In conceptual debates involving the quantum gravity community, the literature discusses the so-called “emergence of space–time”. However, which interpretation of quantum mechanics (QM) could be coherent with such claim? We show that a modification of the Copenhagen Interpretation of QM is compatible with the claim that space–time is emergent for the macroscopic world of measurements. In other words, pure quantum states do not admit space–time properties until we measure them. We call this approach “Achronotopic” (ACT) Interpretation of QM, which yields (...) a simple and natural interpretation of the most puzzling aspects of QM, such as particle-wave duality, wave function collapse, entanglement, and quantum superposition. Our interpretation yields the same results in all measurements as the Copenhagen Interpretation, but provides clues toward the sub-Planckian physics. In particular, it suggests the non-existence of quantum gravity in the conventional sense understood as the quantization of a classical theory. (shrink)

The minimal ingredients to describe a quantum system are a Hamiltonian, an initial state, and a preferred tensor product structure that encodes a decomposition into subsystems. We explore a top-down approach in which the subsystems emerge from the spectrum of the whole system. This approach has been referred to as quantum mereology. First we show that decomposing a system into subsystems is equivalent to decomposing a spectrum into other spectra. Then we argue that the number of subsystems (the volume of (...) the system) can be inferred from the spectrum itself. In local models, this information is encoded in finite size corrections to the Gaussian density of states. (shrink)

We consider the question of whether thermodynamic macrostates are objective consequences of dynamics, or subjective reflections of our ignorance of a physical system. We argue that they are both; more specifically, that the set of macrostates forms the unique maximal partition of phase space which (1) is consistent with our observations (a subjective fact about our ability to observe the system) and (2) obeys a Markov process (an objective fact about the system’s dynamics). We review the ideas of computational mechanics, (...) an information-theoretic method for finding optimal causal models of stochastic processes, and argue that macrostates coincide with the “causal states” of computational mechanics. Defining a set of macrostates thus consists of an inductive process where we start with a given set of observables, and then refine our partition of phase space until we reach a set of states which predict their own future, i.e. which are Markovian. Macrostates arrived at in this way are provably optimal statistical predictors of the future values of our observables. (shrink)

The scientific literature on Wigner’s Friend extended paradox rapidly grew in the last years. A sign that Frauchiger and Renner (2018)’s argument caught an important point. Indeed, they conclude that either we must abandon the universal validity of quantum mechanics, or a certain kind of traditional objective knowledge is impossible. We investigate this contradiction through a logico-epistemic toolbox. We show that abandoning the transmissibility of knowledge, as proposed by many kinds of relational approaches to quantum mechanics, is a heavy epistemological (...) renouncement. Perhaps, it is better to bite the bullet and accept Frauchiger and Renner’s contradiction, until a new revolutionary solution will appear. (shrink)

In a recent paper as an alternative to models based on the notion of ideal mathematical point, characterized by a property of separatedness, we considered a viewpoint based on the notion of continuous change, making use of elements of a non-classical logic, in particular the fuzzy sets theory, with events represented as spatiotemporally blurred blobs. Here we point out and discuss a number of aspects of this imperfect symbolic description that might potentially be misleading. Besides that, we analyze its relation (...) to various concepts used commonly to model physical systems, denoted by terms like: point, set, continuous, discrete, infinite, or local, clarifying further how our viewpoint is different and asking whether, in light of our main postulate, any of these notions, or their opposites, if exist, are in their usual meanings suitable to accurately describe the natural phenomena.

Big History expands the scope of historiography to study all the past, from the Big Bang to the present. Big History is decidedly non-anthropocentric, recognising that humans appeared only very recently from a much deeper past. The Bloomsbury Handbook of Big History brings together an international cast of leading and emerging scholars from a range of disciplines to provide the first comprehensive and balanced exploration of this new and increasingly significant field. -/- The handbook considers the ways in which Big (...) History broadens the scope of evidence historians use. It reveals how Big History allows for the use of information signals from the past, such as material remains, languages, ancient DNA, and fossils, using recently discovered techniques such as carbon-dating, the extraction of ancient DNA, and the analysis of background radiation from the origin of the universe. -/- Understanding Big History requires an examination of the ontology and epistemology of the past and its scientific inference and representation; chapters on the ontology of the past, historical information, historiographic experiments and predictions, the origin and the end of history, historical counterfactuals, contingency, necessity, and determination and under-determination of the past are included to facilitate this understanding. The handbook also provides a sustained analysis of the theoretical assumptions associated with synthetic historical science: the syntheses of genetics, linguistics, and archaeology to infer human prehistory, quantum physics and cosmology to infer the origin of the universe, and environmental science and biology to infer the history of life; as well as the distinct historical sciences and their methods: cosmology, evolutionary biology, geology, archaeology, historical linguistics, and human historiography. -/- This ground-breaking volume is vital reading for all historians, philosophers and historical scientists interested in becoming more scientifically self-conscious when adopting philosophical, theoretical, and methodological approaches to the past.

Renormalization group (RG) theory, while proposed to study particle physics, has found its usage in a large variety of topics over the years, including other physics branches like solid state physics, fluid mechanics, cosmology, machine learning and even non-physics fields like biology, epidemiology, economics, psychology, sociology and so on. The omnipresence of renormalization group theory thus raises the philosophical question of what are the common features of the systems that enable the employment of RG theory and what can be revealed (...) by using the RG method, why renormalization group theory is the naturally approach to deal with these problems and what is the essential point that leads to organizing the system according to renormalization group flow, i.e., order and disorder. These question are addressed in this paper. (shrink)

Over the past decade, the physics literature on torsionful non-relativistic gravity has burgeoned; more recently, philosophers have also begun to explore this topic. As of yet, however, the connections between the writings of physicists and philosophers on torsionful non-relativistic gravity remain unclear. In this article, we seek to bridge the gap, in particular by situating within the context of the existing physics literature a recent theory of non-relativistic torsionful gravity developed by philosophers Meskhidze and Weatherall (Philos Sci, https://doi.org/10.1017/psa.2023.136, 2023) we (...) also discuss the philosophical significance of that theory.

The research challenges the conventional view of unified space and time, arguing that significant contradictions arise when applying this framework to phenomena at extremely small scales.

This perspective integrates ‘subjective’ and ‘objective’ time into (...) a unified framework through a derived equation. (shrink)

Of the many ways of getting at the core of the weirdnesses in quantum mechanics, there’s one which traces back to Schrödinger’s seminal 1935 paper, and has to do with the apparent fuzzy nature of the reality described by the formalism through the wavefunction $$\psi$$ ψ. This issue, which I will be calling the Determinacy Problem, is distinct from the standard measurement problem of quantum mechanics, despite Schrödinger himself ends up conflating the two. I will argue that the Determinacy Problem (...) is an exquisitely philosophical problem, for as it is standard when facing any phenomenon which appears to have indeterminate or fuzzy characteristics, the solutions available are to either blame the deficiencies of our language, or our lack of knowledge, or to blame the world itself. These three attitudes can already be found in the literature on quantum mechanics, either explicitly or implicitly, and they appear to motivate three very distinct research programs: high-dimensional realism, primitive ontology, and quantum indeterminacy.

There is solid consensus among physicists and philosophers that, in gauge field theory, for a quantity to be physically meaningful or real, it must be gauge-invariant. Yet, every “elementary” field in the Standard Model of particle physics is actually gauge-variant. This has led a number of researchers to insist that new manifestly gauge-invariant approaches must be established. Indeed, in the foundational literature, dissatisfaction with standard methods for reducing gauge symmetries has been expressed: Spontaneous symmetry breaking is deemed conceptually dubious, while (...) gauge fixing suffers the same limitations and is subject to the same criticisms as coordinate choices in General Relativity. An alternative gauge-invariant proposal was recently introduced in the literature, the so-called “dressing field method” (DFM). It is a mathematically subtle tool, and unfortunately prone to be confused with simple gauge transformations, hence with standard gauge fixings. As a matter of fact, in the physics literature the two are often conflated, and in the philosophy community some doubts have been raised about whether there is any substantial difference between them. Clarifying this issue is of special significance for anyone interested in both the foundational issues of gauge theories and their invariant formulation. It is thus our objective to establish as precisely as possible the technical and conceptual distinctions between the DFM and gauge fixing. (shrink)

The spin-j Einstein–Podolsky–Rosen–Bohm experiment is examined in the context of how the quantum theoretic probability distributions for the spin measurement outcomes are to be coarse-grained in order to yield classical behavior in the $$j \rightarrow \infty $$ limit. A coarse-graining protocol is found that can be viewed as imperfection either in the detection process or in state preparation process, and is in both viewpoints minimal in the sense that it is no more than what is needed to wash out the (...) execess quantum correlations. In the first point of view the coarse-grained distribution can be written in terms of a Bell-type factorizable hidden variable model wherein the conditional distributions for the spin measurement outcome of each particle is not just nonnegative but actually attains the value zero for some choice of measurement axis. In the second point of view the coarse-grained distribution arises from a spin state whose Wigner function is not just nonnegative but actually attains the value zero for some spin orientations. That such a remarkable dual interpretation should be possible suggests that this type of complementary coarse graining is an intrinsic aspect of how classicality is obtained in the large j limit, but this conclusion remains speculative.

The following article is a portrait of the French sociologist, philosopher, Systems thinker and public intellectual Edgar Morin. It aims to present the life and works of Edgar Morin to a German speaking audience. Introductory in nature, it does not claim to offer more than a concise, contemporary, and, where needed, critical summary of Edgar Morin’s main theoretical tenets. It proceeds by offering, first,abrief overview of Morin’sbiography and a loose sketch of his position in the landscape of French 20th century (...) philosophy. Based on a close reading of Edgar Morin’s chief theoretical oeuvre, La Méthode, it subsequently reconstructshis thought in four steps, payingattention toa) to the context of Morin’s specific intellectual concerns and his new cosmological »method«, b) to his theory of nature, c) to his theory of society, and d) finally to his ethics. The profile which should emerge from this procedure is one of an intellectual who is grapplingwithawide-spanning, holistic thinking; whose working style is transdisciplinary and directed against academic specialisation; and whose philosophical concerns centre around the normativeexpectations of classical humanism. EdgarMorin is a thinker who invites us to think with him through matters of the contemporary world, and his viewpoints are herediscussed and critically evaluated with particular reference to the relevance of his thought for the ecological discourse, and for the current challenges of ›knowledge societies.‹.

Being aware of the scarcity of research in the fields of History and Philosophy of Science and the Philosophy of Chemistry for Chemistry Education, this endeavor aimed to discuss conceptions about the relevance of the dialectical unity between theoryand practicefor the development of Chemistry in the fields of Philosophy of Science and Philosophy of Chemistry, from a Marxist perspective. To support this work, we focused on the understanding of practice in Vázquez's Philosophy and in the Philosophy of Chemistry, in summary: (...) the understanding of this category as the concretization of human teleological activity in the material world, while in science it manifests in an interdependent way with theory, in a dialectical movement. In this way, a discussion was held based on the literature in Philosophy of Science that relates to this dialectical unity, criticizing discourses that prioritize theory in order to rethink the Philosophy of Science Curriculum for Chemistry Teaching Degrees and include the philosophical specificities of Chemistry in these courses. Finally, it is noted that the characteristics of Chemistry as a utilitarian science, its pragmatism, and its relational epistemology place it in a position as an ideal technoscientific knowledge to embody this dialectical unity between theory and practice in scientific practice.

The concept of a “chemical speciation”, as defined by in the year 2000, is grounded in an empiricist semantics. It is a static concept, as it is associated with the ontological category of the chemical state of the distribution of chemical species in a system and is further restricted to chemical species of a single element as it excludes chemical species with more complex chemical systemic subunits, such as molecular species, crystals, or nanoparticles. In this work, we propose a new (...) definition of “chemical speciation” based on a semantics of meaning, applying Mario Bunge’s philosophical system. Chemical speciation is the distribution of chemical systemic subunits amongst defined chemical species in a system. Additionally, we propose two dynamic concepts associated with chemical speciation: chemical species transformation and chemical species evolution. These concepts aim to account for the chemical changes that explain both the diversity of chemical species sharing common systemic subunits and the historical emergence of new modes of chemical speciation. These modes, in turn, explain the appearance of new systemic chemical subunits and novel substantial properties. Our definitions have the advantage of being consistent with general theories of the evolution of matter, such Assembly Theory. Additionally, at the chemical level, this approach encompasses broader systemic chemical subunits beyond elemental particles, allowing for the chemical speciation of families of molecules, crystals, nanoparticles, etc. Finally, our proposal offers the advantage of overcoming the issue of arbitrariness in choosing the reference systemic chemical subunit by linking this choice to the concepts of substantial property, and function.

Molecular structure is one of the dispositional attributes of the molecule and counted as an example of affordances. This attribute has been systematically exploited through the development of theories and practice of organic chemistry. (Ochiai 2023, pp. 141–149) The question to be addressed in this study is whether we can legitimately claim that this type of attribute is real. To answer the question, we first clarify what is worthy of the word ‘reality’ in scientific arguments. Whitehead claims that a physical (...) substance like electron is a bundle of spatial-temporal experience. (Mesle 2008, p. 36) The contention is that we cognize the causal relationships of the physical world through the experience of events. What we cognize as real is not unchanging matter but various kinds of events we experience. Based on this recognition we examine the nature of affordances. Affordances are the context-relative dispositional attributes of {agent-world} complexes. (Harré 2014, pp. 77–91; Harré and Llored 2018, pp. 167–186) The affordance of a knife becomes actualized through our experience of cutting. In this way affordances are concerned with work or the function of something useful. They are materialized as tools. This suggests that affordances are real, and so is molecular structure. Molecular structure is characterized by a certain function which molecules show in organic synthesis. Other dispositional attributes of molecules that become actualized in the context of organic chemistry are also examined. We refer to the physical significance of wavefunctions as well, which we discussed in the previous study. (Ochiai 2023, pp. 359–367) Creating function, we expand a world we cognize as real. This view of the world we name ‘functional realism.’ Our conceptual scheme is supported by Quine’s holism. (shrink)

Prelog’s model was one of the first empirical models to explain the stereoselectivity of the Grignard reactions of 2-oxocarboxylic acid esters bearing a chiral alcohol. Prelog constructed his model based on some assumptions regarding the conformation of chiral 2-oxocarboxylic acid esters to explain the relationship in configuration between the chiral alcohol starting materials and the 2-hydroxycarboxylic acid products. Construction of the model involves four steps: (1) mentally analyzing the reactants to identify the basic stereochemical structures, (2) assuming the conformations of (...) the chiral alcohol moiety as the main reasons for stereoselectivity, (3) modeling the transition states to explain the relationship in configuration between the chiral alcohols and 2-hydroxycarboxylic acids, and (4) validating the evidence to revise the model. The process of constructing this historically pivotal model may have implications for science education, especially for developing theories from extensive data. The four steps from the Prelog’s model were compared with the models for boiling points of hydrocarbons and solubility of amino acids. (shrink)

At the commencement of the universe and in the deep past of the observable realm, the first three minutes is a topic both scientifically challenging and philosophically intriguing. While the universe is believed to have undergone drastic changes over this short period, scientists seem to have essential difficulties with gaining observational evidence and conceiving physics in high-energy conditions. This essay delves into philosophical issues concerning evidence, inference, methodology, and the standard for legitimate scientific knowledge about the early universe. Focusing on (...) three central scientific topics, the Big Bang nucleosynthesis, cosmic inflation, and multiverse, I analyze how scientists employ various forms of evidence, methods, and inferences to achieve remarkable success in obtaining detailed knowledge. It also turns out that those topics face different epistemic challenges and deserve different degrees of credibility. A feature of the early universe is the philosophical root of debates in science. I exemplify this by showing that debates about inflation and the multiverse stem from philosophical disagreements about standards for scientific explanation and the significance of hypothesis testing. I conclude by situating the philosophy of the early universe in the context of big history and pinpointing how it shapes our picture of “the beginning of everything”. (shrink)

The causal principle of the Kalām cosmological argument—Everything that begins to exist has a cause—remains controversial. One common objection is that while the principle may apply to things within the universe, it does not apply to the universe itself. Here, I argue that if the universe began uncaused, then there is an extremely high probability that the universe began just moments ago with the appearance of age. However, I further argue that the general agreement of independent estimates for the universe’s (...) age provides powerful empirical evidence that if the universe began to exist, then the universe has a cause.

"الرؤية الكونية" هو مصطلح يجب أن يعني مجموعة من الأسس التي تنبثق منها فهم منهجي للكون، ومكوناته كالحياة، والعالم الذي نعيش فيه، والطبيعة، والظواهر البشرية، وعلاقاتها. إنه، بالتالي، مجال من الفلسفة التحليلية يغذيه العلوم، وهدفه هو هذا المعرفة المجمعة والمستدامة معرفيًا عن كل ما نحن عليه ونحتويه، وما يحيط بنا، وما يرتبط بنا بأي شكل من الأشكال. إنه شيء قديم قدم الفكر البشري، وبالإضافة إلى استخدام عناصر من علم الكونيات العلمي، فإنه (...) يشمل كل شيء في الفلسفة والعلوم الذي يشير إلى الكون والحياة. الرؤية الكونية ليست مجموعة من الأفكار والفرضيات والافتراضات بل هي نظام قائم على الملاحظة والتحليل والدليل والتوضيح. لا تهدف أي رؤية كونية إلى التعريف أو التأسيس أو الاقتراح بل فقط إلى الفهم والتحليل والتفسير. كل منا يبني وينقل رؤيته الكونية طوال حياته، دون إنشاء أشكال، كخلفية لتفكيرنا وسلوكنا. لغويًا، قد يشتق مصطلح "الرؤية الكونية" من الألمانية، ويعادل مفهوم "Weltanschauung"، كما استخدمه عدة فلاسفة. ومع ذلك، فإن هذه العلاقة اللغوية غير قابلة للتطبيق لأنها تتعارض مع ما نقترحه كرؤية كونية. تشير هذه الكلمة الألمانية إلى رؤية واقعية قبل منطقية أو أولية، ذات سياق حدسي وبعيدة عن المعرفة النقدية التي لم تكن موجودة بعد في وقت صياغتها. بلا شك، تحتوي الرؤى الكونية، بالمعنى الذي نفهمها، وتستخدم هذه العناصر الأولية أو قبل المنطقية التي تشمل التاريخ واللاوعي الجماعي وكل النماذج التي نحملها. ومع ذلك، في المفهوم الذي نطبقه هنا، تتجاوز الرؤية الكونية هذا المحتوى بكثير، أولاً من خلال إخضاعه باستمرار للتفكير النقدي الحالي، وأخيرًا من خلال جعل التجربة التحليلية (وليس التفكير نفسه أو الحدس) كونها الفعلي. يعرض أنطونيو لوبيس اتساع هذا المحتوى: "الرؤى الكونية ليست نتاج الفكر. لا تنبع من الرغبة البسيطة في المعرفة. إن استيعاب الواقع هو لحظة مهمة في تكوينها، ولكن، مع ذلك، هي واحدة فقط. إنها تأتي من السلوك الحيوي، ومن تجربة تقييم الحياة، ومن هيكل كليتنا النفسية. إن رفع الحياة إلى الوعي في معرفة الواقع، وفي التقييم، وفي الواقع الإرادي هو العمل البطيء والشاق الذي قامت به الإنسانية في تطوير مفاهيم الحياة. (ديلتاي، 1992 [1911]: 120)"(1) في هذا العمل، نسعى إلى تحديد رؤية كونية تستند إلى الحقائق التي تقدمها العلوم اليوم. لا نقترح، في أي وقت، أن نقوم بالعلم؛ أو نظري الفلسفة، لكننا سنسعى دائمًا لأن ندعم بها أو، على الأقل، نحتمي بها من التشوهات المعرفية التي نحملها عادة.

हम सोच कर दुनिया नहीं बनाते। दुनिया को समझ कर हम सोचना सीखते हैं। कॉस्मोविज़न एक ऐसा शब्द है जिसका मतलब नींव का एक समूह होना चाहिए जिससे ब्रह्मांड, जीवन के रूप में इसके घटकों, जिस दुनिया में हम रहते हैं, प्रकृति, मानवीय घटनाओं और उनके संबंधों की एक व्यवस्थित समझ उभरती है। इसलिए, यह विज्ञान द्वारा पोषित विश्लेषणात्मक दर्शन का एक क्षेत्र है, जिसका उद्देश्य हम जो हैं और जो हमारे चारों ओर है, और जो किसी भी तरह से (...) हमसे संबंधित है, उसके बारे में यह एकत्रित और ज्ञानमीमांसीय रूप से स्थायी ज्ञान है। यह मानव विचार जितना ही पुराना है, और वैज्ञानिक ब्रह्मांड विज्ञान के तत्वों का उपयोग करने के अलावा, यह दर्शन और विज्ञान में ब्रह्मांड और जीवन को संदर्भित करने वाली हर चीज को शामिल करता है। एक कॉस्मोविज़न विचारों, परिकल्पनाओं और मान्यताओं का एक समूह नहीं है, बल्कि अवलोकन, विश्लेषण, साक्ष्य और प्रदर्शन पर आधारित एक प्रणाली है। कोई भी कॉस्मोविज़न परिभाषित करने, स्थापित करने या प्रस्तावित करने का इरादा नहीं रखता है, बल्कि केवल समझने, विश्लेषण करने और व्याख्या करने का इरादा रखता है। हममें से प्रत्येक व्यक्ति अपने सोच और व्यवहार के लिए पृष्ठभूमि के रूप में, रूपों को स्थापित किए बिना, जीवन भर अपने कॉस्मोविज़न का निर्माण और परिवहन करता है। भाषाई रूप से, "कॉस्मोविज़न" शब्द जर्मन से लिया गया है, जो कई दार्शनिकों द्वारा इस्तेमाल किए गए "वेल्टनशाउंग" की अवधारणा के बराबर है। हालाँकि, यह भाषाई संबंध लागू नहीं होता है क्योंकि यह हमारे द्वारा प्रस्तावित ब्रह्मांड-दृष्टि के विपरीत है। यह जर्मन शब्द वास्तविकता के एक पूर्व-तार्किक या प्रोटो-प्रयोगात्मक दृष्टिकोण को संदर्भित करता है, जिसमें एक सहज संदर्भ होता है और आलोचनात्मक ज्ञान से बहुत दूर होता है जो इसके निर्माण के समय भी अस्तित्व में नहीं था। निस्संदेह, ब्रह्मांड-दृष्टि, जिस अर्थ में हम उन्हें समझते हैं, इन प्रोटो-प्रयोगात्मक या पूर्व-तार्किक तत्वों को समाहित करता है और उनका उपयोग करता है जिसमें इतिहास, सामूहिक अचेतन और हमारे द्वारा धारण किए जाने वाले सभी मूलरूप शामिल हैं। हालाँकि, जिस अवधारणा को हम यहाँ लागू करते हैं, उसमें ब्रह्मांड-दृष्टि इस सामग्री से बहुत आगे निकल जाती है, सबसे पहले इसे लगातार वर्तमान आलोचनात्मक सोच के अधीन करके, और अंत में विश्लेषणात्मक अनुभव (और न कि विचार या अंतर्ज्ञान) को अपना वास्तविक ब्रह्मांड बनाकर। एंटोनियो लोपेस इस विषय-वस्तु की व्यापकता को उजागर करते हैं: "ब्रह्मांडीय दर्शन विचार की उपज नहीं हैं। वे जानने की सरल इच्छा से उत्पन्न नहीं होते हैं। वास्तविकता की समझ इसकी संरचना में एक महत्वपूर्ण क्षण है, लेकिन फिर भी, यह केवल एक है। यह जीवन के मूल्यांकन के अनुभव से, और हमारी मानसिक समग्रता की संरचना से, जीवन को वास्तविकता के ज्ञान में, मूल्यांकन में, और इच्छाधारी वास्तविकता में चेतना तक ऊपर उठाना वह धीमा और कठिन कार्य है जो मानवता ने जीवन की अवधारणाओं के विकास में किया है।" -/- .
