Topic: John Lucas (philosopher)


  
  John Lucas (philosopher) - Wikipedia, the free encyclopedia
John Randolph Lucas (born 18 June 1929) is a British philosopher.
Lucas is perhaps best known for his paper "Minds, Machines and Gödel," arguing that an automaton cannot represent a human mathematician.
A prolific author with unusually diverse teaching and research interests, Lucas has written on the philosophy of mathematics, especially the implications of Gödel's incompleteness theorem, the philosophy of mind, free will and determinism, the philosophy of science with special reference to special relativity, causality, political philosophy, ethics and business ethics, and the philosophy of religion.

 [No title]
Lucas himself seems to have seen his argument as showing that the nature of the human mind is mysterious and has little to do with the physics and chemistry of the brain, but Penrose wishes to draw a very different conclusion.
He mistakenly believes that he has a philosophical disagreement with the logical community, when in fact this is a straightforward case of a mathematical fallacy.
In particular, Lucas confused the ordinary language statement that the methods mathematicians use are consistent with the very complex mathematical\longpage{13pc}\pagebreak\ statement which would arise if we applied the G\"odel Theorem to a hypothetical formalization of those methods.

 Lucas' Theorem
Lucas' Theorem, due to the great Oxford Philosopher John Lucas FBA, explains why both these hypotheses are impossible.
Some of their philosophers went so far as to suggest that "everything is a number".
John Lucas FBA was an Oxford Philosopher until his retirement in the 1990s.

The Zombie philosophers, such as Daniel Dennett and the husband and wife team Pat and Paul Churchland, argue that this is a mistaken question.
John Lucas, the Oxford philosopher who first formulated the Goedelian arguments against artificial intelligence later developed by Roger Penrose, concluded his paper with the words: "Since the time of Newton, the bogey of mechanist determinism has obsessed philosophers.
No longer on this count will it be incumbent on the natural philosopher to deny freedom in the name of science: no longer will the moralist feel the urge to abolish knowledge to make room for faith.

 Le Mars Daily Sentinel: Story: Concluding The Probe Of Science Vs. Religion
Both Godel's Theorem and Lucas' argument are extremely subtle, but we can state the gist of them as follows.
Lucas observed that if a man were HIMSELF a computer program, then by knowing how his own program was put together he could outwit himself, which is a contradiction.
However, a human being, Lucas noted, CAN recognize his own consistency - at least at times - and so must be more than a mere computer.

 ZENIT Special Report: Star Wars
They had come to the weekly general audience of John Paul II to listen to the leader of over 1 billion Catholics exhort them to live their faith, mature in their beliefs and to deepen their prayer life in the tradition of centuries of mystics and saints.
Lucas' words have been selected from an interview with Bill Moyers published in the April 26 edition of Time Magazine on the "Theology of Star Wars" and the words of the Pope have been translated directly from the original text of the general audience on May 19 mentioned above.
JOHN PAUL II: Certain practices originating from the great oriental religions are especially attractive to contemporary man. To these, Christians should apply a spiritual discernment so as never to lose from sight the concept of prayer as it is illustrated in the Bible throughout the whole history of salvation.

He is also a recreational mathematician and controversial philosopher.
In this controversial book, he argues this based on claims that humans can do things outside the power of formal logic systems, such as knowing the truth of unprovable statements, or solving the halting problem.
These claims were originally made by the philosopher John Lucas of Merton College, Oxford.

 Philosophical Themes from CSL:
In this re-run, Anscombe defended her original position while philosopher John Lucas undertook to uphold Lewis’ side of the debate.
Today’s philosophers are no less puzzled by the phenomenon of intentionality than he was.
The philosophically sophisticated may be able to skip this section, in which naturalism is roughly defined as the doctrine according to which there exists nothing intentional or not belonging to space and time (other than perhaps space and time themselves) which is neither reducible to, nor supervenient upon, non-intentional, spatio-temporal realities.

As Daniel Dennett, the philosopher, puts it: 'Complex systems can in fact function in what seems to be a thoroughly ‘purposeful and integrated’ way simply by having lots of subsystems doing their own thing without any central supervision.' The self, then, is not what it seems to be.
There are philosophers of the future and experts on the subjects of robotics and artificial intelligence who are certain that on some far-off day the most pressing moral issue humans will face will be how to distinguish ourselves from lifelike machines.
Advocates of what the philosopher John Haugeland famously characterized as GOFAI (good old-fashioned artificial intelligence) create hand-crafted intricate models that are often powerful yet too brittle to be used in the real world.

 STS Diary -- May, 1996   (Site not responding. Last check: 2007-07-20)
John Harrison, the book's subject, was a reclusive rural clockmaker who invented the chronometer, solving a problem that had eluded scientists for two centuries: how to navigate accurately at sea.
John Harrison drew upon the discoveries of previous inventors, from Galileo, who invented a navigation helmet for observing the heavens, to Sir Isaac Newton and Edmond Halley; Einstein's theory of relativity had crucial antecedents in the electromagnetic theories of James Clerk Maxwell and Michael Faraday.
In 1961, John Lucas -- an Oxford philosopher known for espousing controversial views -- published a paper in which he purported to show that a famous theorem of mathematical logic called Godel's second incompleteness theorem implies that human intelligence cannot be simulated by a computer.

 The Ontological Argument
Like many other philosophical arguments it has suffered by being made out to be more rigorous than in the nature of the case it can be.
In some cases the doubts of the philosophers may have been silly, but it is difficult to dismiss them all without abandoning philosophy altogether.
If we adopt the maxim that in order to make out what a philosopher means, we should consider what his arguments for the thesis actually prove, and what, in his opinion, follows from it, then Descartes' `God' is to be construed as `Reality'.

Lucas stated that there is a need to maintain the ombudsperson at each Divisional meeting because there were problems at the most recent meetings.
Lucas replied that a good placement officer should broker for their students these very things and wondered if the APA could work out a suitable solution.

He was born around 484 B.C., and it is important to note that Euripides associated extensively with the philosophers of his time.
He was one of the last pre-socratic philosophers and shared many similar ideas to Socrates himself.
It is clear that these characters are created with the influence of Anaxagoras' "Nous" theory as an attempt to proove that the mind is always in control, yet does not always act ethically.

John Fonte did a great job yesterday in documenting the role of Republicans in passing the 1964 Civil Rights Act.
Taking a full two days to "respond" to my critique of their silly self-congratulatory discussion of the draft, the gang at Tapped ignores all of the substance of my remarks to accuse me -- and the Corner -- of being unserious, in a "I know you are but what am I?" tone.

Dennett the philosopher was born in 1942 in Beirut, where his father had gone to complete a Harvard PhD in Islamic history at the American University, and his mother (from Minnesota) was teaching English at the American Community School.
The Oxford philosopher John Lucas had published a paper - still famous - arguing that Gödel's theorem disproved any theory that humans must be machines, and that human thought could be completely simulated on a computer.
I'd think 'Descartes is wrong, Quine's wrong; Lucas is wrong!' But that's what philosophers do: they find an eminent target, and they think, let's see if I can figure out how to say what's wrong with this.

Not only Hume presented an original view of causality, but even to this day philosophers seem to ignore the fact that causality in science is not the same as in philosophy, and that Hume’s definitions are essential in the practice of modern science.
This is what philosophers call the ceteris paribus conditions (all else left unchanged), but for the scientist this is not an unfortunate constraint: it is the essence of their experimental skill.

In vain I expostulated, pointing out that he had been the most influential moral philosopher in the second half of the twentieth century, whose arguments had had to be considered by everyone else who thought about the subject.
For a tutor, even more so than for a philosopher generally, disagreement is as valuable as agreement.

In 1965 at Cambridge, Penrose and physicist Steven Hawking proved that singularities (such as fl holes) could be formed from the gravitational collapse of dying immense stars.
This is based on claims that human consciousness transcends formal logic systems because things such as the insolvability of the halting problem and Gödel's incompleteness theorem restrict an algorithmically based logic from traits such as mathematical insight.

 Review of GOD, TIME, AND KNOWLEDGE
Third, it correctly situates the philosophical dispute over foreknowledge and freedom within its proper theological context and in so doing highlights the intimate connection between the doctrines of divine omniscience and divine providence.
This is especially significant because much of the recent literature has been oblivious to the complications that arise once we take seriously the traditional theistic tenet that God, far from being a passive observer of the universe, is in fact its sovereign and provident governor.
True, he is not the only distinguished contemporary Christian philosopher to have travelled this road; Richard Swinburne, John Lucas, and Peter Geach have preceded him.
