Peter Ludlow (born January 16, 1957), who also writes under the pseudonym Urizenus Sklar, is currently[when?] a professor of philosophy at Northwestern University. Before moving to Northwestern, Ludlow taught at University of Toronto, the University of Michigan, and the State University of New York at Stony Brook. He has done much interdisciplinary work on the interface of linguistics and philosophy—in particular on the philosophical foundations of Noam Chomsky's theory of generative linguistics and on the foundations of the theory of meaning in linguistic semantics. He has worked on the application of analytic philosophy of language to topics in epistemology, metaphysics, and logic, among other areas.

Ludlow has also established a research program outside of philosophy and linguistics. Here, his research areas include conceptual issues in cyberspace, particularly questions about cyber-rights and the emergence of laws and governance structures in and for virtual communities, including online games. In recent years Ludlow has written nonacademic essays on hacktivist culture and related phenomena such as Wikileaks. He has just[when?] accepted a position at Rutgers University's Center for Cognitive Science (RUCCS).

Education

Ludlow received his PhD in philosophy from Columbia University in 1985 under the direction of Charles Parsons, but also studied with Noam Chomsky and James Higginbotham at MIT. He received his B.A. in 1979 from Bethel College.

Philosophy of generative linguistics

Ludlow's work in generative linguistics has revolved around three basic themes.The first theme is that generative linguistics at its best is concerned with understanding and explanation, and not just with observation and data gathering. To this end, generative linguistics is interested in underlying mechanisms that give rise to language related phenomena, and this interest will often trump the goal of accumulating more data.

The second theme is what he calls the "Ψ-language hypothesis". It is the hypothesis that the underlying mechanisms (the more basic elements) posited by generative linguists are fundamentally psychological mechanisms and that generative linguistics is a branch of cognitive psychology, but against Noam Chomsky's I-Language hypothesis Ludlow argues that it doesn’t follow that cognitive psychology must therefore be interested in mental states individuated solely by what happens inside the language user's head. It is consistent with the Ψ-language hypothesis that psychological states (and indeed syntactic states) are individuated in part by the embedding environment.

The third theme is what Ludlow calls the principle of "methodological minimalism". It is the thesis that best theory criteria like simplicity and formal rigor cannot be given theory neutral definitions, and thus must really come down to one thing: seek methods that help linguists to do their jobs with the minimum of cognitive labor.

Foundations of semantics

Ludlow's earliest work in semantics was an attempt to combine work in the theory of meaning with contemporary work in generative linguistics, but using resources that are more parsimonious than those typically used in semantic theory—for example without using the higher-order functions and intensional objects deployed in Montague grammar. The resources were largely limited to primitives like truth and reference to individuals.

His subsequent work has explored ways of formalizing alternative approaches to semantic theory—including the possibility of formalizing a Wittgensteinian use theory or expressivist semantics for natural language, which is to say a theory in which the building blocks of a semantic theory are expressions of attitudes rather than primitives like truth and reference.[1]

Philosophy of language

Intensional transitive verbs

Ludlow's PhD dissertation defended a proposal dating back to the medieval logician Jean Buridan, and revived by W.V.O. Quine in philosophy and James McCawley in linguistics, according to which so-called "intensional transitive verbs" like "seek" and "want" are really propositional attitudes in disguise. He has subsequently developed these ideas in collaboration with the linguists Richard Larson and Marcel den Dikken.

Interpreted logical forms

Ludlow's paper with the semanticist Richard Larson, "Interpreted Logical Forms", advocated a quasi-sententialist view of propositional attitude verbs (a view that has been criticized by Scott Soames in Chapter 7 of his book Beyond Rigidity). Ludlow's response to Soames involves the idea that propositional attitude reports are not supposed to correspond to some fact about what is going on inside the agent's head but rather are created by a speaker S, for the benefit of a hearer H, to help H form some theory about the agent being reported on. Crucial to this account is the idea that the lexicon is dynamic and that speakers engaged in conversation will negotiate the coinage of terms "on the fly" in constructing attitude reports.[2]

The dynamic lexicon

Ludlow's work on Interpreted Logical Forms has led to the development of a view of linguistic meaning according to which meaning shifts are much more common than intuition suggests. He rejects the "common coin" view of word meaning, and argues that word meanings are negotiated on the fly as conversational partners build little microlanguages together. These ideas have subsequently been applied to controversies in epistemology (see below).

Implicit comparison classes

In his article "Implicit Comparison Classes"[3] Ludlow argues for the syntactic reality of comparison class variables in adjectival constructions. That is, when one says "the elephant is small", there is an implicit variable for the comparison class (in this case elephants, as in "small for an elephant"), and that variable is represented by the language faculty. That work was influential in subsequent work on the context sensitivity of language by Jason Stanley and Zoltán Gendler Szabó, and has played a role in debates about contextualism in contemporary epistemology.

Contextualism in epistemology

Recent work in epistemology has pushed back against skepticism by arguing that knowledge attributions are context sensitive—our standards of knowledge vary from context to context. So, while in a philosophy class I may not know I have hands, in other contexts (for example, chatting in a bar) I do. Ludlow initially argued that there were implicit argument positions for standards of knowledge.[4] In response to criticism from Jason Stanley in his book "Knowledge and Practical Interests", Ludlow has advanced a doctrine that he calls "Cheap Contextualism".[5] The idea is that on the dynamic lexicon view, shifts in word meaning are ubiquitous, and the meaning of the term "know" is not an exception. Contextualism in epistemology is just a consequence of these garden variety shifts in meaning.

Natural logic

Ludlow has written a series of papers on the logical form of determiners (words like "all", "some", and "no") and has pursued the idea that their most interesting properties can be given purely formal or syntactic accounts. The work borrows from one of the central ideas of medieval logic—the hypothesis that all the key logical inferences can be reduced down to just two basic inferences that are sensitive to whether the syntactic environment was dictum de omni or dictum de nullo—classical notions that are basically equivalent to the contemporary notions of upward and downward entailing environments. To explain, in an upward entailing (de omni) environment a superset can be substituted for any set. In a downward entailing environment a subset may be substituted for a set. Ludlow revives the medieval project by combining it with the descriptive tools of contemporary Chomskyan linguistics and recent technical work in formal logic.

Presentism and tensism

Ludlow's first book, Semantics, Tense, and Time, was devoted to arguing that presentism, a metaphysical thesis that denies the reality of past and future events, is consistent with the intuitive truth of much of our tensed discourse. More recently, he has argued that while tense is an ineliminable feature of reality, the resulting position (called "tensism") does not force us to be presentists.

Conceptual issues in cyberculture

Criticizing the Greek god model of governance

Most of Ludlow's work on cyberculture has centered on the question of governance for virtual worlds and he has been critical of what he calls the "Greek god model" of virtual world governance. This is a model in which virtual world platform owners do not have coherent systematic policies to deal with in world disputes, but rather reach in and dabble as suits their dispositions at the moment. In an e-book entitled "Our Future in Virtual Worlds" Ludlow argues that as our lives continue to move online, the Greek god model becomes ever more dangerous. This critique has been extended to social networking platforms more generally.[6]

Online gaming chonicles

Ludlow founded The Alphaville Herald on October 23, 2003. It was the unofficial newspaper for the Alphaville server of The Sims Online, where Ludlow used the avatar Urizenus Sklar. Its stories uncovered in-game scams and cyber-prostitution, and highlighted Electronic Arts' indifference to the social problems in their game.

In a famous controversy, reported in the New York Times[7] and elsewhere (including law journals[8]), Ludlow was kicked out of The Sims Online after some blistering editorials against Electronic Arts Corporation for their failures at managing and policing the gamespace. The newspaper subsequently migrated to another virtual world, Second Life, in June 2004.

The Herald has been written about in Wired[9] and the Columbia Journalism Review.[10] Ludlow (in the voice of Urizenus Sklar) is currently a Contributing Editor, while the avatar Pixeleen Mistral, revealed by Ludlow in 2010 to be Internet pioneer Mark P. McCahill, is the newspaper's Managing Editor.

Ludlow and Mark Wallace wrote a book about The Herald and its exploits called "The Second Life Herald: the Virtual Tabloid that Witnessed the Dawn of the Metaverse" (MIT Press, 2007). The book received the American Association of Publishers, Professional/Scholarly Publishing award for “Best Book in Media and Cultural Studies, 2007”, was named a Choice “Outstanding Academic Title, 2008”, and Library Journal honored it as a “Top Sci-Tech Book, 2007,” (they ranked it one of top 39 science books of 2007 and top book in category of Computer Science).

MTV.com has described Ludlow as the "Unwelcome Guest" in the "10 most influential video game players of all time" because of his chronicles about online video games. In particular MTV wrote that EA revoked Ludlow's "online citizenship" in The Sims Online, allegedly because the “offense was Ludlow's publication of a "TSO"-centric newspaper that chronicled creative and sometimes troublesome behavior of other gamers in the world, including allegations that under-age players were involved in virtual-sex-related activities. EA claimed Ludlow's newspaper violated the terms of service for playing "TSO"” and that Ludlow later similarly chronicled the game Second Life with his "The Second Life Herald."[11]
