Abraham Pais (Continued). Feeling excited this morning, I know not why. Began when I turned to edit scientific-theology.com chapter 3. Went to sleep last night reading Walter Farrell whose over the top rendition of Aquinas highlights the deficits in the ancient models of God and gives impetus to my need to remodel the theory of creation. Abraham Pais: Einstein and quantum theory
Pais page 873: 'Einstein's contributions to physics fall under three main heading: statistical physics, quantum theory and relativity theory. His researches in statistical physics and on quantum theory are strongly related.'
Statistics arise when probability theory is applicable, that is where the outcome of an event (like the toss of a coin) is not constrained by nature to uniqueness, that is specific resolution is lacking giving rise to uncertainty in reality or (from a classical deterministic point of view) in knowledge. Andrey Nikolaevich Kolmogorov: Foundations of the Theory of Probability
[page 263]
Pais page 874: '. . . when we come to Einstein's role as a transitional figure it will become evident that wave mechanics is an offspring of statistical physics in a sense to be described.'
A guess: Einstein's statistical approach to quantum mechanics explains von Neumann's discovery that quantum measurement causes an increase in entropy [through increased definition] and gives us grounds to apply the theory of evolution to the early ('pre-animate', pre-DNA/RNA) stages of the evolution of the universe. John von Neumann (2014): Mathematical Foundations of Quantum Mechanics (Chapter 5)
Einstein: ' "Planck's theory makes implicit use of the light quantum hypothesis" (1906b)
Einstein: ' "We must consider the following theorem to be the basis of Planck's radiation theory: the energy of a [Planck oscillator] can only take values that are integral multiples of hν ; in emission and absorption the energy of the [Planck oscillator] changes in jumps which are multiples of hν".
page 876: 'Five experimental observations have largely shaped the physics of the twentieth century . . . photoelectric effect, x-rays, radioactivity, the Zeeman effect and the electron.
Einstein: ' "simplest picture": a light quantum gives all its energy to a single electron . . . Emax = hν - P (work function).'
page 878: Einstein; ' "It is my opinion that the next phase in the development of theoretical physics will bring us a theory of light which can be interpreted as a kind of fusion of the wave and emission theory . . . the wave structure and the quantum
[page 264]
structure are not to be considered as mutually incompatible." (1909)
Pais page 880: ' In 1871 Boltzmann (showed that the average kinetic energy equals the average potential energy for a system of particles, each one of which oscillates under the influence of external harmonic forces.'
'Before Einsteins paper of 1906 it was not realize that the diamond [specific heat] anomaly was to be understood in terms of . . . the inapplicability . . . of the classical equipartition theorem.'
page 881: 'Sommerfeld (1968) "Degrees of freedom must be weighed, not counted".'
page 882: Third law of thermodynamics: ' "As the temperatures tends to absolute zero the entropy of a system tends to a universal constant which is independent of chemical or physical composition or any other parameters in which entropy may depend. This constant can be taken to be zero".'
We would expect the third law to apply to the initial singularity which has of itself no temperature and no energy if it is a pure quantum of action, although the big bang people would like it to have infinite T and E.
page 884: ' Throughout his scientific career quantum physics remained a crisis phenomenon for Einstein.'
' [The] main discoveries [of the old quantum theory] concerned quantum
[page 265]
rules for stationary states of matter and pure radiation.'
Pais page 884: ' . . . advances on [the interaction between matter and radiation] became possible only after the advent of quantum field theory when the concepts of particle creation and annihilation were formulated.'
These concepts nevertheless obeyed conservation of energy, momentum spin and other quantum numbers which play a role analogous to matter in hylomorphism [and suggest the existence of deeper strata of structure underneath the particle zoo].
A quantum of action is a potential which is released by action and the rate of action varies as the potential so conserving energy. So we might say the initial singularity has divine potential which is shared out among the little singularities (quanta of action) that proceed from it; something like this [which is related to the idea that the initial singularity is the fundamental hardware of the universe through which all information in the universe flows, rather like the origin of a Hilbert space]. This might immediately open the way to gravitational potential which is a function of mass / energy. The quantum is bursting to act, like a puppy let off its chain [and we are following the Christian paradigm for solving the problem of creation by attributing the initial singularity with the power [potential] to create a universe].
page 893: Boltzmann's axiom: ' identical particles that cannot come infinitely close to one another can be distinguished by their initial conditions and by the continuity of their motion.' Schroedinger (1955) 'Nobody before Boltzmann held it necessary to define what one means by the [the term] "same material point".'
page 895: Bose derivation of Planck's law introduced three new features: 1) Photon number nonconservation; 2) Boltzman's axiom is gone, just count, do not distinguish; 3) Statistical independence of particles is gone.
[page 266]
Pais page 895 (continued): 'The astounding fact is that Bose was correct on all three counts (In his paper he commented on none of them). I believe there has been no such successful shot in the dark since Planck's introduction of the quantum in 1900.'
Pais page 896: Bose-Einstein condensation Bose-Einstein condensate - Wikipedia
Bosons are correlated by totally symmetric wave functions. Boson - Wikipedia
Bose Einstein gas satisfies third law of thermodynamics (?). Levy, Kosloff & Alicki: Quantum refrigerators and the third law of thermodynamics
page 897: de Broglie Louis de Broglie - Wikipedia
page 900: Born: Absolute square of ψ is a probability density.
Einstein to Born: ' "Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot but it does not really being us closer to the secret of the 'old one' ".'
page 907: Einstein ' "I am not sure that differential geometry is the framework for further progress, but if it is then I think I am on the right track".'
Aquinas: his logic is good but his principles [hypotheses] can be doubted.
New particles: ' E felt that the time was not ripe to worry about such things and that these particles wild eventually appear as solutions of the equations of a unified theory.' Equations are [in effect] crossed lines defining a fixed point [their solution].
[page 267]
Pais page 907 (continued): E on Newton; ' " The enormous practical success of his theory may have prevented him and the physicists of the eighteenth century from recognizing the fictitious character of the principle of the system".' We can say this about the Roman Catholic Church.
E: " The fictitious character of the principles is made obvious by the fact that it is possible to exhibit two essentially different bases [Newtonian mechanics and relativistic mechanics] each of which in its consequences leads to a large measure of agreement with experience."
Pais 910: ' " In my opinion there is the correct path and . . . it is in our power to find it. Our experience up to date justified us in feeling sure that in Nature is actualized the ideal of mathematical simplicity".'
What we learn from entanglement and spooky action at a distance is there here there is action at a distance but no definite information is carried so we have randomness, a feature of Hilbert space. To make things definite and informative we have to introduce spacetime by interactions between Hilbert spaces to give Minkowski space.

So we put Hilbert space, angels, music and games of chance on the low resolution level of the universe which begins with sic et non and gradually builds up to transfinite strings of bits, since every decision along the way may be taken to be binary. Carlo Rovelli: Relational Quantum Mechanics
[page 268]
Might we think that photons do not move in spacetime (where we consider the velocity of light to be impossible) but rather in the underlying Hilbert-like space where logic and quantum mechanics rule and since time and distance do not exit independently so the velocity of light is in effect fixed [and remains fixed when time and space separate]. We are trying to save the angels by giving them a role such as this, messengers.
An orchestral sound is a superposition of superpositions: each instrument produces a superposition of all its normal modes and then thee are al siperposed to create the orchestral sound.

Biographical dreams, putting my life in focus as a coherent story, predicting a promising future, rather late in life. Maybe prompted by jump in web traffic. I do not promote sit and very few hits come from search engines so there must be a bit of interaction going on between readers but nobody send me emails from the sites so it is not easy to tell what is going on, but encouraging nevertheless and the world I am doing seems to be worthwhile. Pais's article on Einstein emphasizes his early success and then slowdown in later life. Maybe my lifetime of relative failure and anonymity will presage something better to come. Dreaming is a good way to motivate work.
Biological logic is largely [stereo] chemical logic with various shaped molecules binding to one another starting with simple structures like H2 and building up to very complex protein operated machinery like the Krebs cycle and ribosomes. The same general

Not much in this diary. All my energy is going into the revision of the scientific theology site, and I am coming to the heart of the book, trying to explain the creation of the divine world with just two principles: the unbounded activity of a divinity of pure action; and the sculpting force of consistency embodies in the principle that local contradictions cannot exist [ie attempts at existence lead to annihilation]. I am now at the interface between the classical and the quantum worlds, and will sped the weekend trying to work out the next steps forward. I am still in love with my network model [chapter 5 and Prolegomenon] and I want to mould it to fit the three methods of counting in statistical mechanics, classical, bose-einstein and fermi-dirac, coupling these to Noether, continuity and symmetry to get a broad picture. Schwinger's quantum action principle - Wikipedia, Bose-Einstein statistics - Wikipedia, Fermi-Dirac statistics - Wikipedia, Noether's theorem - Wikipedia, Jeffrey Nicholls: Prolegomenon to Scientific Theology
[page 269]
Want to go from counting to quantum mechanics via probability and statistics, where the bins are symmetries [and] complete systems of events, ie continuous in the Noether sense of nothing happens in a symmetry, that is in a bin. We have three basic bins, classical, bose and fermi.

Darwin, Charles, On the Origin of Species: A Facsimile of the First Edition, Harvard University Press 2001 Amazon review: 'It was a very happy idea to publish a facsimile of the first edition of On the Origin of Species; the price of copies of the original edition has reached the thousand dollar bracket, and in contemporary literature all page-references are to the original pagination, which was not followed in previous reprints of the first edition. Now, with this very reasonably priced and beautifully produced book, not only historians of science but also biologists will have the opportunity of following the fascinating thought-trails, still far from fully explored, of that remarkable man Darwin. Few if any persons are so well qualified as Harvard's Ernst Mayr to execute so helpfully and gracefully the delicate task of writing a worthy foreword to such a classic.'

Dawkins, Richard, The Selfish Gene , Oxford UP 1976 Amazon: Editorial review: 'Inheriting the mantle of revolutionary biologist from Darwin, Watson, and Crick, Richard Dawkins forced an enormous change in the way we see ourselves and the world with the publication of The Selfish Gene. Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since.' Rob Lightner

Farrell (1974), Walter, A Companion to the Summa: Volume 1 The Architect of the Universe, Christian Classics / Sheed & Ward 1941 - 1974 Preface: 'This volume attempts to put in popular form St. Thomas' masterly study of God, man and the world in the Prima Pars of his Summa Theologica. His study is of extreme pertinence to our times precisely because we are the victims of a constantly increasing intellectual confusion. We have become more and more timid about digging beneath the surface of life, more and more emphatic about the knowledge of facts and less and less concerned with the wisdom of beginnings and ends. . . . For the world is intelligible only in terms of man and God; man is intelligible only in terms of God: God is intelligible only in terms of Himself.'

Homer, and E V Rieu (translator), D C H Rieu (editor), Peter Jones (Introduction), The Odyssey, Penguin Classics 2010 Product Description
'The epic tale of Odysseus and his ten-year journey home after the Trojan War forms one of the earliest and greatest works of Western literature. Confronted by natural and supernatural threats - shipwrecks, battles, monsters and the implacable enmity of the sea-god Poseidon - Odysseus must use his wit and native cunning if he is to reach his homeland safely and overcome the obstacles that, even there, await him.
About the Author
HOMER is thought to have lived c.750-700 BC in Ionia and is believed to be the author of the earliest works of Western Literature: The Odyssey and The Iliad. E. V. RIEU was a celebrated translator from Latin and Greek, and editor of Penguin Classics from 1944-64. His son, D. C. H. RIEU, has revised his work. PETER JONES is former lecturer in Classics at Newcastle. He co-founded the 'Friends of Classics' society and is the editor of their journal and a columnist for The Spectator.'

Hume, David, and J C A Gaskin, Principal Writings on Religion Including Dialogues Concerning Natural Religion and the Natural History of Religion , Oxford University Press 2009 David Hume is one of the most provocative philosophers to have written in English. His Dialogues ask if a belief in God can be inferred from what is known of the universe, or whether such a belief is even consistent with such knowledge. The Natural History of Religion investigates the origins of belief, and follows its development from polytheism to dogmatic monotheism. Together, these works constitute the most formidable attack upon religious belief ever mounted by a philosopher. This new edition includes Section XI of The Enquiry Concerning Human Understanding and a letter by Hume in which he discusses Dialogues.

Kolmogorov, Andrey Nikolaevich, and Nathan Morrison (Translator) (With an added bibliography by A T Bharucha-Reid), Foundations of the Theory of Probability, Chelsea 1956 Preface: 'The purpose of this monograph is to give an axiomatic foundation for the theory of probability. . . . This task would have been a rather hopeless one before the introduction of Lebesgue's theories of measure and integration. However, after Lebesgue's publication of his investigations, the analogies between measure of a set and mathematical expectation of a random variable became apparent. These analogies allowed of further extensions; thus, for example, various properties of independent random variables were seen to be in complete analogy with the corresponding properties of orthogonal functions . . .'

Revised English Bible, Revised English Bible, Oxford University Press, USA 2003 From Library Journal
'From its inception the New English Bible was intended to be revised. This revision, which has taken into account praise and criticism of the New English Bible and advances in biblical scholarship, is the fruit of 15 years' labor. The style has remained dignified but not stuffy, vigorous but not coarse. Many Briticisms and awkward phrases have been reworked ("loose livers" in I Cor. 5:9 is now "those who are sexually immoral"), though some remain ("a rod in pickle" in Prov. 19:29). The removal of "thee" and "thou" from address to God and the cautious, discriminating use of inclusive language reflect current usage. Transposition of words, verses, and whole passages in the name of clarity--carried over from the New English Bible --will cause continued concern and will decrease somewhat this work's value as a study Bible. All things considered, however, this is an excellent translation that will easily find a place in public and private reading. Highly recommended.

Weinberg, Steven, The Quantum Theory of Fields Volume I: Foundations, Cambridge University Press 1995 Jacket: 'After a brief historical outline, the book begins anew with the principles about which we are most certain, relativity and quantum mechanics, and then the properties of particles that follow from these principles. Quantum field theory then emerges from this as a natural consequence. The classic calculations of quantum electrodynamics are presented in a thoroughly modern way, showing the use of path integrals and dimensional regularization. The account of renormalization theory reflects the changes in our view of quantum field theory since the advent of effective field theories. The book's scope extends beyond quantum elelctrodynamics to elementary partricle physics and nuclear physics. It contains much original material, and is peppered with examples and insights drawn from the author's experience as a leader of elementary particle research. Problems are included at the end of each chapter. '

'Humans regulate intergroup conflict through parochial altruism; they self-sacrifice to contribute to in-group welfare and to aggress against competing out-groups. Parochial altruism has distinct survival functions, and the brain may have evolved to sustain and promote in-group cohesion and effectiveness and to ward off threatening out-groups. Here, we have linked oxytocin, a neuropeptide produced in the hypothalamus, to the regulation of intergroup conflict. In three experiments using double-blind placebo-controlled designs, male participants self-administered oxytocin or placebo and made decisions with financial consequences to themselves, their in-group, and a competing out-group. Results showed that oxytocin drives a "tend and defend" response in that it promoted in-group trust and cooperation, and defensive, but not offensive, aggression toward competing out-groups.'. back |

And though all the winds of doctrine were let loose to play upon the earth, so Truth be in the field, we do injuriously, by licensing and prohibiting, to misdoubt her strength. Let her and Falsehood grapple; who ever knew Truth put to the worse, in a free and open encounter. (1)
Two centuries after Milton, in the same year in which Charles Darwin published the Origin, John Stuart Mill's essay On Liberty (2) added further arguments for the free exchange of ideas, suggesting that such exchange is vital for intellectual and social health. Although both Milton and Mill stand behind our current acquiescence in the value of extensive free discussion, both of them knew that they were opposing ancient suspicions about the viability of democracy. The political theorists and philosophers of the Greco-Roman world viewed ordinary folk as vulnerable to deception and exploitation. Allowed to determine the direction of the state, the folk would be easily seduced into believing falsehoods aligned with the interests of charismatic leaders, so that the popular voice would enthusiastically clamor for disastrous policies. Better, then, to entrust the ship of state to wise navigators, whose wisdom embraced both depth of understanding and moral integrity.'. back |

The following topics will be discussed : The light-quantum hypothesis and its gradual evolution into the photon concept. Early history of the photoelectric effect. The theoretical and experimental reasons why the resistance to the photon was stronger and more protracted than for any other particle proposed to date. Einstein's position regarding the Bohr—Kramers—Slater suggestion, the last bastion of resistance to the photon. Einstein's analysis of fluctuations around thermal equilibrium and his proposal of a duality between particles and waves, in 1909 for electromagnetic radiation (the first time this duality was ever stated) and in January 1925 for matter (prior to quantum mechanics and for reasons independent of those given earlier by de Broglie). His demonstration that long-known specific heat anomalies are quantum effects. His role in the evolution of the third law of thermodynamics. His new derivation of Planck's law in 1917 which also marks the beginning of his concern with the failure of classical causality. His role as one of the founders of quantum statistics and his discovery of the first example of a phase transition derived by using purely statistical methods. His position as a critic of quantum mechanics. Initial doubts on the consistency of quantum mechanics (1926—1930). His view maintained from1930 until the end of his life: quantum mechanics is logically consistent and quite successful but it is incomplete. His attitude toward success. His criterion of objective reality. Differences in the roles relativity and quantum theory played in Einstein's life. His vision regarding quantum theory in the context of a unified field theory. His last autobiographical sketch, written a few months before his death, concluding with a statement about the quantum theory, a subject to which (by his own account)he had given more thought than even to general relativity.' back |

Bose-Einstein condensate - Wikipedia, Bose-Einstein condensate - Wikipedia, the free encyclopedia, ' A Bose–Einstein condensate (BEC) is a state of matter (also called the fifth state of matter) which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (-273.15 °C). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum phenomena, particularly wavefunction interference, become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density, about one-hundred-thousandth (1/100,000) the density of normal air, to ultra-low temperatures.
This state was first predicted, generally, in 1924–1925 by Albert Einstein following and crediting a pioneering paper by Satyendra Nath Bose on the new field now known as quantum statistics.' back |

They may be either elementary, like the photon, or composite, as mesons. All force carrier particles are bosons. They are named after Satyendra Nath Bose. In contrast to fermions, several bosons can occupy the same quantum state. Thus, bosons with the same energy can occupy the same place in space.' back |

I suggest that this incorrect notion that generates the unease with quantum mechanics isthe notion of observer-independent state of a system, or observer-independent values of physicalquantities. I reformulate the problem of the interpretation of quantum mechanics as the problemof deriving the formalism from a set of simple physical postulates. I consider a reformulation ofquantum mechanics in terms of information theory. All systems are assumed to be equivalent, thereis no observer-observed distinction, and the theory describes only the information that systems haveabout each other; nevertheless, the theory is complete.' back |

In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest components of metabolism and may have originated abiogenically. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three segments of the citric acid cycle have been recognized.' back |

A statement can also just refer to known objects, and the proof assistant will answer whether the fact is ‘obviously’ true or false based on its current knowledge. If the answer is not obvious, the user has to enter more details. Proof assistants thus force the user to lay out the logic of their arguments in a rigorous way, and they fill in simpler steps that human mathematicians had consciously or unconsciously skipped.' back |

He outlined an explanation for the disparity between matter and antimatter in the universe. His idea of gravitation as the quantum elasticity of the spacetime continues to inspire the search for a unified theory. He was a pure theorist who invented the Soviet H-bomb and, 20 years later, transformed into the foremost human-rights advocate and opponent of the Soviet regime, for which he received a Nobel peace prize.

Over the course of several years, the two photographers wandered the country documenting sites that are contested both literally and symbolically – on the land and in the public consciousness: Palestinian towns that were destroyed in 1948, unrecognized Bedouin villages, and a string of locales abutting the route of Green Line. Using a variety of technologies, the duo created a detailed mapping of Israel – precisely in places the state sought to erase, obstruct and conceal.' back |
Gluon - Wikipedia, Gluon - Wikipedia, the free encyclopedia, ' A gluon (/ˈɡluːɒn/) is an elementary particle that acts as the exchange particle (or gauge boson) for the strong force between quarks. It is analogous to the exchange of photons in the electromagnetic force between two charged particles.[6] In layman's terms, they "glue" quarks together, forming hadrons such as protons and neutrons.
In technical terms, gluons are vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics (QCD). Gluons themselves carry the color charge of the strong interaction. This is unlike the photon, which mediates the electromagnetic interaction but lacks an electric charge. Gluons therefore participate in the strong interaction in addition to mediating it, making QCD significantly harder to analyze than quantum electrodynamics (QED). ' back |

Instruction in the basic principles of science, in particular, can not properly be called indoctrination, in the sense that the fundamental principles of science call for critical self-evaluation and skeptical scrutiny of one's own ideas, a stance outside any doctrine.[3] In practice, however, a certain level of non-rational indoctrination, usually seen as miseducative, is invariably present.[4] The term is closely linked to socialization; in common discourse, indoctrination is often associated with negative connotations, while socialization refers to cultural or educational learning' back |

James Fieser, Hume: Writings on Religion [The Internet Encyclopedia of Philosophy], 'David Hume ranks among the most influential philosophers in the field of the philosophy of religion. He criticized the standard proofs for God‘s existence, traditional notions of God’s nature and divine governance, the connection between morality and religion, and the rationality of belief in miracles. He also advanced theories on the origin of popular religious beliefs, grounding such notions in human psychology rather than in rational argument or divine revelation. The larger aim of his critique was to disentangle philosophy from religion and thus allow philosophy to pursue its ends without either rational over-extension or psychological corruption.' back |

God, but they also saw the world as a very imperfect place. Their reaction was to place God outside the world.

Levy, Kosloff & Alicki, Quantum refrigerators and the third law of thermodynamics, ' Abstract: The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to absolute zero. The third law of thermodynamics is then quantified dynamically by evaluating the characteristic exponent ζ of the cooling process dT(t)/dt∼−Tζ when approaching absolute zero, T→0. A continuous model of a quantum refrigerator is employed consisting of a working medium composed either by two coupled harmonic oscillators or two coupled two-level systems. The refrigerator is a nonlinear device merging three currents from three heat baths: a cold bath to be cooled, a hot bath as an entropy sink, and a driving bath which is the source of cooling power. A heat-driven refrigerator (absorption refrigerator) is compared to a power-driven refrigerator. When optimized, both cases lead to the same exponent ζ, showing a lack of dependence on the form of the working medium and the characteristics of the drivers. The characteristic exponent is therefore determined by the properties of the cold reservoir and its interaction with the system. Two generic heat bath models are considered: a bath composed of harmonic oscillators and a bath composed of ideal Bose/Fermi gas. The restrictions on the interaction Hamiltonian imposed by the third law are discussed. In the Appendices, the theory of periodically driven open systems and its implication for thermodynamics are outlined.' back |

William Edward Morris, David Hume (Standord Encyclopedia of Philosophy), 'First published Mon Feb 26, 2001; substantive revision Fri May 15, 2009
The most important philosopher ever to write in English, David Hume (1711-1776) — the last of the great triumvirate of “British empiricists” — was also well-known in his own time as an historian and essayist. A master stylist in any genre, Hume's major philosophical works — A Treatise of Human Nature (1739-1740), the Enquiries concerning Human Understanding (1748) and concerning the Principles of Morals (1751), as well as the posthumously published Dialogues concerning Natural Religion (1779) — remain widely and deeply influential. Although many of Hume's contemporaries denounced his writings as works of scepticism and atheism, his influence is evident in the moral philosophy and economic writings of his close friend Adam Smith. Hume also awakened Immanuel Kant from his “dogmatic slumbers” and “caused the scales to fall” from Jeremy Bentham's eyes. Charles Darwin counted Hume as a central influence, as did “Darwin's bulldog,” Thomas Henry Huxley. The diverse directions in which these writers took what they gleaned from reading Hume reflect not only the richness of their sources but also the wide range of his empiricism. Today, philosophers recognize Hume as a precursor of contemporary cognitive science, as well as one of the most thoroughgoing exponents of philosophical naturalism.' back |
