  Strange loop - Wikipedia, the free encyclopedia
A strange loop is a case of self-reference which affects (or even damages) the original item, possibly causing a paradox.
This, by itself, is not enough to be a strange loop (it is merely self reference, and is common practice for a compiler).

Strange loop phenomena emerge "whenever, by moving upwards (or downwards) through the levels of some hierarchical system, we unexpectedly find ourselves right back where we started" (10).
The resolution, curiously enough, is a loop at the core of Greenblatt's cultural poetics: the structure of the archive determines for us the units of perception within which we view traces of culture, to determine the structure of the archive.
As we observed at the outset here, the infinity of the loop is not inherent in the structure of the output but in the way we choose to make sense of the patterns, what we imagined to have preceded the present text and to be likely to come after.

Escher realized Strange Loops in several different ways, and they can be arranged according to the tightness of the loop.
In the examples we have seen of Strange Loops by Bach and Escher, there is a conflict between the finite and the infinte, and hence a strong sense of paradox.
That is because the Strange Loop is buried in the oyster--the proof.

In evolution and learning, one such strange loop, the Baldwin effect, was proposed over a century ago, and has been studied computationally for the past 15 years.
Similarly, the redistribution effect occurs in simulation under specific initial conditions: too little vitamin C in the environment, and its synthesis it is never fully masked; too much vitamin C, and the abilities required to acquire it are not tightly integrated.
Both the Baldwin and the redistribution effects can be considered strange loops in the interactions between genotype and phenotype in evolution.

is a loop that allows such a system to "perceive itself", to talk about itself, to become "self-aware", and in a sense it would not be going too far to say that by virtue of having such a loop, a formal system acquires a self.
In general self-replication of a system can be characterised by tangled hierarchies or Strange Loops and emergent/complex behaviour when a network is created between the individual components of the system within the confines of a selective environment.
Strange loopiness arises because of context-sensitivity in proteins (as illustrated by the IFU and beta-strand pairing example).

As I have suggested, some strange loops between performance and technology were installed very early on in the formation of the field, loops which can be traced to the first theorist Schechner lists in his outline of performance studiesÕ intellectual history: Gregory Bateson.
In fact, restored behavior can be thought of as the ÒmicroÓ loop within an immense feedback system whose ÒmacroÓ loops Schechner began inventing earlier in his career: the relations of entertainment and efficacy, of aesthetic and social drama, and of theatre and ritual were all theorized using feedback concepts.
These loops, formative to the performance studies paradigm, situate the embodied, transformational practices of performance somewhere between those of ritual and theatre, in a liminal space of historic proportions.

 RE: strange loops
While I haven't looped specifically in the terms you mentioned yet, there are a couple of things I like to do which evolve loops musically in addition to evolving using sonic textures.
One is to begin a loop in a certain key, or with the illusion of a certain key, and then gradually introduce certain specific notes which give the loop a dissonant quality, and then bring out the tone of a new key, resolving the perceived dissonance.
Another idea I like is to bring out different modal ideas from a loop either by evolving the loop, soloing different ways along with it, or by adding to it, and then subtracting again, and then going somewhere else...

Loosely defined, Strange Loops are observed in hierarchical systems wherein by moving upwards (or to a higher plane) or downwards (to a lower plane), we end up at where we have started.
The loop essentially represents a never-ending process in a finite number of steps; the concept of infinity is inherently ingrained in Strange Loops.
There is Strange Loop inherent in Gödel's work, to prove the "Incompleteness Theorem", one has to embark upon writing a self-referential Mathematical statement.

It is strange for at least two reasons: 1) The more you try and figure it out, the more you get stuck inside and 2) If you stop trying to figure it out and start "living it out," the more, uh, strange things get.

Strange Loops are a kind of iteration, and there is also a correspondence to be found in fractal geometry.
The iterations of Strange Loops could also be compared with those present in the feedback cycle of chaos and order.
Strange Loops, feedback cycles, and iterations are mechanisms of the creative complexity of intelligence; they are, for Hofstadter, the retrieval mechanisms of inner meaning.

 Philosophy of science - Wikipedia, the free encyclopedia
Arguments made against greedy reductionism through reference to emergent phenomena rely upon the fact that self-referential systems can be said to contain more information than can be described through individual analysis of their component parts.
Examples include systems that contain strange loops, fractal organisation and strange attractors in phase space.
Analysis of such systems is necessarily information-destructive because the observer must select a sample of the system that can be at best partially representative.

 Identity and Cultural Exchange 600-1600: Philippa Semper, 'The stranger within: Ohthere at the Court of King Alfred'
He is also a stranger to the language in which his account is described, and to the concerns of local, national and international identity that are addressed through the insertion of his account into the Orosius and the interaction of that account with the geo-political description of Northern Europe.
His 'strangeness' on all these fronts forms the underside to the superficially smooth appropriation of the Orosius by the OE translator, resulting in an uneasy acculturation that is unpicked even as it is woven in.
In its fragmentary representation of identity, the text can only gesture towards a cultural experience that cannot be recovered; in its operation through structures of simple and complex difference and likeness, it traces the outline of a strange loop that threatens to turn back on itself and dissolve the very identity it delineates.

I think that Girard is entitled to ridicule a whole book that fantasizes about these "strange loops" to "explain" in an awkward and almost mystical language what can be done in one page, like Girard just does in the article.
Excursion into scientific things that have nothing to do with his philosophical musings (no, there's no connection between Goedel and whatever "strange loops" Hofstadter thinks are in his brain), are designed to fool the gullible and impressionable reader into thinking that his thesis has some kind of scientific legitimacy.
Strange loop just means recursive representation, and is neither undefined nor intended to be mystical.

Escape from strange loops requires the establishment of a hierarchy that enables clear judgments and suggests directions or guidelines for action.
We need new development strategies that (1) increase our understanding of the educational process and its reform, (2) recognize the complexities of the domain, and (3) are based on better analyses and utilization of systemic and programmatic information.

 Eric's Recommended Books
Hofstadter demonstrates strange loops in logic, brain and mind, mathematics, philosophy, computers, and DNA.
Strange loops allow a system to say things about itself, and hence a mind can think about itself and a mathematical system can prove itself to be incomplete.
More than that, a strange loop has a power on the system; it affects and constrains the system.

 Geoff Arnold: Douglas Hofstadter in town [UPDATED]
He gave a lecture to our Phil.of Mind class at Tufts entitled "What is it like to be a strange loop?", and he's talking at the Media Lab in MIT tomorrow.
In GEB, you may remember, the strange - and unexpectedly stable - patterns generated by pointing a video camera at the screen displaying its output were a powerful example (and metaphor) for the way these ideas come together.
(2) My interpretation of "strange loops" is that Doug is talking about feedback loops that cross various kinds of boundaries: between the physical and the cognitive, between the outside world and the I-in-the-world (in terms of action and perception), and across minds (from one person to another).

He talks about how hand washes other hand and two people converse, and though a loop is present in such an action, it does not feel strange.
But it would not feel strange because there was no hierarchy present to begin with.
On the other hand, where language does create strange loops is when it talks about itself, whether directly or indirectly.

 Flatline_Constructs 4.7 Capitalism as Toy Story: Hyperfiction, Strange Loops and Rhizomes
Increasingly, children are presented with toys and fictional systems which emerge together, in a loop.
At one level, the strange loop is a way of describing chicken-and-egg processes in which the product of any process is also one of its founding presuppositions.
Which is to say: what might ultimately separate the strange loop from the rhizome is that, in the former, hierarchy is simply tangled, whereas in the latter it is radically abolished.
