1. The Cartesian Mind: Reflections on Language and Music. Indian Institute of Advanced Study, Simla, 2000


The work examines some of the fundamental discoveries of contemporary linguistic theory, also known as generative grammar, to conclude that the basic computational architecture of human language is not linguistically specific; in that sense the architecture is likely to cover other cognitive domains unique to humans. One such domain is music; there must be many others such as arithmetic, kinship relations, map-making, and the like. Keeping to music in this work, it is claimed that, at a certain level of theoretical description, the mental systems that enter into the creation of linguistic and musical expressions are one and the same. The system so uncovered matches the Cartesian conception of mind in the right joints.

2. The Architecture of Language by Noam Chomsky. Edited by N. Mukherji, B.N. Patnaik and R.K. Agnihotri. Oxford University Press, New Delhi, 2000


This book consists of an edited transcript of a lecture, delivered at the University of Delhi in January 1996, where Chomsky reflects on the overall history of the generative enterprise to relate it to some strikingly novel advances in grammatical theory, called the ‘Minimalist Program’. Integrating philosophical and conceptual issues with empirical research, he sketches some of the key issues that have characterised generative grammar in recent years to chart out the agenda for future research in language theory. The transcript tries to retain the lively, engaging style for which Chomsky is renowned as a public speaker. The discussion that followed the lecture was a lively event on the scope of linguistics, language acquisition, and the theory of the language and mind. In his extensive responses to a set of wide-ranging questions, Chomsky goes much beyond the issues raised in the lecture itself. The volume includes extensive clarificatory notes and references. While linguists interested in the internal history of generative linguistics will find this an immensely insightful work, it will be useful also for students and general readers who wish to gain an introductory knowledge of the discipline and its overall significance.

3. The Primacy of Grammar  The MIT Press, Cambridge, 2010; Prentice-Hall EEE, 2011; MIT Paperback 2012.


Biolinguistics has been able to maintain some distance from topics that are traditionally thought to be central to the study of language: meaning, concepts, truth-conditions, and communication. This is not to suggest that what currently falls under the non-grammatical aspects of language will never be a part of grammatical theory. But, as with matured sciences, the chances are that each such incorporation will be hard-fought, since it will have to be formulated, not due to pressures from ‘outside,’ but from within the evolving framework of biolinguistics. This restriction to grammar, so delinked from ‘language,’ opens the possibility that the computational system of human language may be involved in each cognitive system that requires similar computational resources. A mixture of analytical argumentation, varieties of empirical (including introspective) evidence, and some speculation suggests a picture in which a computational system consisting of very specific principles and operations is likely to be centrally involved in each articulatory symbol system that manifests unboundedness. In this restricted sense, the object of biolinguistics exemplifies the Cartesian picture of a united mind. In other words, the suggestion is that the following things converge: (a) the scientific character of biolinguistics, (b) its isolation from the rest of science and, thus, from the rest of human inquiry, (c) its basic explanatory form, namely, the computational-representational framework, and (d) the domains of its application.




It is a sign of maturity for any given field that a philosopher should reflect on its foundations. When the philosopher understands the field in its technical minutiae, it is a privilege, even a contribution. Moreover, given its approach and scope, a work like Mukherji's should reach a wide audience beyond linguistics, which is vital for the dissemination of the biolinguistics project that he elegantly introduces.

This wide-ranging monograph provides a masterly and lucid overview of Chomsky's 'biolinguistics' enterprise and builds on it to offer a novel account of the nature of the human faculty of language. The core of that faculty is our tacit knowledge of grammar, the unique domain where the methodology of the hard sciences has been fruitfully applied to human cognition. In a tightly argued and challenging discussion, Mukherji goes on to suggest that there is a single computational system (essentially Chomsky's CHLthe computational system of human language) underlying all of language, music, mathematics and logic (the 'hominid set'). He defends this speculative thesis with insightful discussion of music, both Indian and Western, and ends with the striking suggestion that CHL is the unique computational system in nature. Mukherji's work is likely to trigger admiration and outrage in equal measure. It is an elegant achievement.

- Neil Smith, Department of Linguistics, University College London



Mukherji's stance is that of a philosopher wanting to tease out what makes grammar special in the landscape of the human sciences and science as such....Overall, Mukherji urges that the computational system of human language is not language specific but restricted to a small number of human domains and thus defines the 'hominid set'. If this thesis turns out to be correct, the part of reality which the study of CHL reveals comes close to what one might expect from an empirical investigation of the mind.... However austere and bleak Mukherji's picture may seem at times, it is a bold and impressive attempt to reorganize the landscape of the philosophy of mind and language.

4. Mind in the Mirror of Language: Humans, Mentality and Merge, Bloomsbury London, Forthcoming


Most living forms in nature display various cognitive abilities in their sensory reactions, locomotion, search for food and mate, etc. No doubt humans share many aspects of cognition with other animals. However, except for humans, no other animal builds fires and wheels, navigates with maps, and tells stories to other conspecifics. The classical philosophers, such as Rene Descartes postulated the mind precisely to mark the distinction between humans and ‘beasts’.



In this light, this study introduces, defends, and begins to develop a novel philosophical approach to the study of mind. I argue for a simple, narrow and species-specific conception of the human mind extracted from the grammatical properties of language. It is shown that the grammatical operation Merge is not domain-specific and is implicated in domains other than language, but it is not implicated in nonhuman domains. Merge may be identified as the mind. The primary aim is to launch a conceptual inquiry into what the human mind ought to look like, which conception is most compelling on grounds of virtual conceptual necessity.



5. Sounds of Thought. In prep.


Following Aristotle, the classical view of language is that language is a system of sound-meaning correlation. A recent proposal, due to Noam Chomsky and others, is that language is basically a vehicle of thought, sound is ancillary, perhaps sound is an evolutionary afterthought designed for articulation of thought. In the book under preparation, this recent view is totally rejected.


It is argued that the view fails to distinguish between articulation and symbolisation. Even if articulation of thought could be viewed  as secondary, the origin of symbols must be primary for the grammatical operation Merge to become operative in the human mind. The sound system provides for the symbolisation of experiential content which are then put together by Merge.


Once we adopt this alternative Aristotelian perspective, we may explain (a) the origin of concepts in humans, (b) absence of them in nonhumans, (c) astonishing variety of sound systems, (d) absence of speech in animals, and a variety of other unresolved issues in inquiries on the human mind.
