 What is Knowledge? A Debate - Paul Rezedes and Mitch Hodge with Graham Dennis - The Examined Life On-Line Philosophy ...
Hodge has not adequately silenced the many objections to it (for instance, the Gettier cases), and thus, although the JTB model may have some validity as a rule of thumb, the model itself does not serve as the ultimate arbiter or standard for deciding what knowledge is.
Hodge’s notions is a commitment to the notion of direct cognitive presence.  This commitment appears in his offering at the Journal, for our consideration, the Butchvarov argument for primary epistemic judgments.  It also appears when he asserts the absurdity of the notion that one might not believe what one believes.  Mr.
Hodge notes in footnote 1 that the JTB model works with theories of truth other than correspondence theory.  To be sure, the Gettier cases can be treated as neutral with respect to the theory of truth at issue, and thus Mr.

 Reformation21 »
No doubt it is tautologically true that Hodge was a child of his time, and no doubt he could have benefited from the philosophy of science of children of later times, which claims that scientific theories are falsifiable hypotheses, not inductive generalizations from the data.
Hodge is concerned to distinguish what he believes to be the correct systematic theological method from two other methods which he calls, somewhat imprecisely as he acknowledges, the 'Speculative' and the 'Mystical'.
However, Hodge refers to 'the truths' of the Bible, and 'the facts of Scripture', and I suppose that he would not deny that these truths and facts are expressed, or are expressible, in propositions.

 Charles Hodge and His Objection to Darwinism: The Exclusion of Intelligent Design
Charles Hodge was born to Hugh and Mary Hodge in Philadelphia in December 1797.
Hodge defines design to be "the intelligent and voluntary selection of an end, and the intelligent and voluntary choice, application, and control of means appropriate to the accomplishment of that end." That design implies intelligence is part of its very nature.
He confirms both that Hodge was correct in his understanding of Darwinism (as defined by Darwin himself) and Christianity (as the mainstream theology throughout its history has understood it) as fundamentally incompatible and that Hodge did accurately represent Christian theological tradition as a whole (Wells 1988:215-223).

 introhodge
Since its introduction, Hodge theory and its variants (variations of Hodge structures, mixed Hodge structures, variations of mixed Hodge structures) have been a source of some of the deepest results in algebraic geoemetry.
More recently the theory of variations of Hodge structures has served as the basis of the theory of Shimura varieties, and, similarly, mixed Hodge structures form a basis for a theory of mixed Shimura varieties, important for the theory of compactifications.
The book under review is a collection of three articles about Hodge theory and related developments, which are all aimed at non-experts and fulfill, in an extremely satisfactory manner, two functions.

 Politically Dead Wrong. Origins & Design 17:2. Wells, Jonathan
But Hodge's opposition to Darwinism was actually based on a notion of design which is central to the Christian tradition, and pervades the writings of every major theologian, so it is a mistake to dismiss him as provincial and outmoded.
This is the essence of Hodge's critique of Darwinism.
Hodge wrote in the heat of intellectual battle, however, when the issues were at least as confusing as they are now.

 Graduate: Math Department, WCAS, Northwestern University
This course is an introduction to abstract ergodic theory, focusing on the asymptotic behavior of measure preserving transformations.
This course will be an introduction, through examples, to some of the ideas of the modern theory of stacks, and to some of the abstract ideas (simplicial sheaves, closed model categories, cosimplicial spaces, homotopy diagrams and their rectification) which are at the heart of a large part of contemporary research in geometry and topology.
In some sense this second phase was the golden era of Hodge theory and since the mid 1970's the subject has played a less central role in mathematics.

The International Centre for Mathematical Sciences, Edinburgh, held a conference from 20-26 July, to commemorate the centenary of Sir William Hodge, the originator of Hodge theory – ‘one of the landmarks in the history of mathematics in the 20th century’ according to Hermann Weyl.
There was a quite spectacular array of speakers, including four Fields Medallists, the world’s leading experts in Hodge theory, former colleagues and students of Hodge such as Fritz Hirzebruch and Sir Roger Penrose, and members of the Hodge family.
Hodge was born in Edinburgh and spent most of his academic career in Cambridge.

 Guitar Columns by David Hodge Lessons - Guitar Noise
David Hodge's core philosophy is that music is meant to be shared and his columns are in written in a wonderfully down-to-earth style that is fun to read and loaded with practical examples.
By David Hodge It is much more important to know how and why something works than it is to "just do it." But the sad fact is that most guitarists truly believe that the art of playing well is strictly a matter for the hands.
By David Hodge The trick to being a better guitarist is you have to be able to work both inside and outside of the box.

 Questions I'm thinking about
Rigid cohomology is a cohomology theory for algebraic varieties over fields of positive characteristic that plays a role similar to that of algebraic de Rham cohomology for varieties over fields of characteristic zero.
It was constructed by Berthelot based primarily on Dwork's proof of the rationality of the zeta function of an algebraic variety (though it also draws from the theory of crystalline cohomology, constructed largely by Berthelot at the behest of Grothendieck).
Hodge theory is the study of the special structure of those vector spaces, and families of vector spaces, which occur as the cohomology of algebraic varieties over the complex numbers.

 Mathematical Sciences Research Institute - Non-Abelian Hodge Theory   (Site not responding. Last check: 2007-10-30)
Together with his students and collaborators, Simpson developed the theory of geometric n-stacks in a form which is particularly well adapted to understanding non-abelian cohomology of complex algebraic varieties as well as their Hodge structures.
An indication of the power of the theory is that even though the notion of a geometric n-stack was invented for the task of understanding non-abelian Hodge structures it immediately acquired a life of its own and keeps popping up in different areas of modern mathematics.
All these indicate that until non-abelian Hodge theory has reached is full maturity it will provide us with new restrictions on the homotopy types and the monodromy of the projective varieties.

 THE HODGE THEORY OF PROJECTIVE MANIFOLDS
This book is a written-up and expanded version of eight lectures on the Hodge theory of projective manifolds.
Though the proof of the Hodge Theorem is omitted, its consequences — topological, geometrical and algebraic — are discussed at some length.
Despite starting with very few prerequisites, the concluding chapter works out, in the meaningful special case of surfaces, the proof of a special property of maps between complex projective manifolds, which was discovered only quite recently.

 Hodge theory and algebraic cycles   (Site not responding. Last check: 2007-10-30)
The Hodge structure of a complex manifold contains detailed information, and Griffiths' Torelli principle says that in many cases it should be enough to determine the manifold.
The primary motivation for the study of algebraic cycles is the famous unsolved Hodge conjecture; work on this has led to new subjects such as motives, relations to K theory and D-modules.
Progress is expected from the overlap between algebraic cycles and problem areas (e, g, h, j, m), for example, related to motivic integration, elliptic genus and Fourier-Mukai transforms.

 Research   (Site not responding. Last check: 2007-10-30)
In our non-compact hyperkähler case even an integration theory was missing; which has recently been adressed in a joint paper with Proudfoot.
Is there a Hodge theoretical L^2-index interpretation of a certain signature, which can be defined on circle compact manifolds using the integration technique in my recent paper with Proudfoot?
I conjecture that for a hyper-compact hyperkähler manifold this signature is always non-positive if the quaternionic dimension is odd and is non-negative if the quaternionic dimension is even; a result which is known for the L^2-signature by a result of Hitchin.
