19Ibid., p. 164.

20John Wilkins had written an Art of Stenography (London 1628), a system of ‘simple analogous symbols’ in which ‘new Illiterall Characters be inuvented and vsed for certained words: betweene which words and their Characters, appeareth some Analogie and proportion of reason’. See Salmon, The Study of Language, p. 160.

31There is an extensive literature on universal languages, universal grammars, universal characters and philosophical languages. See, in S. Auroux (ed.), Histoire des idées linguistiques, vol. II: Le développement de la grammaire occidentale (Liège 1994): ‘Les questions de l'âge de la science’, esp. Vivian Salmon's account of the tradition, ‘Caractéristiques et langues universelles’, pp. 407–23, and Marc Dominicy's bibliographical essay on the history of grammar, ‘Le programme scientifique de la grammaire générale’, pp. 424–41. See also James Knowlson, Universal Language Schemes in England and France, 1600–1800 (Toronto 1975); Mary M. Slaughter, Universal Languages and Scientific Taxonomy in the Seventeenth Century (Cambridge and New York 1982); Umberto Eco, La Ricerca della lingua perfetta nella cultura europea (Rome and Bari 1993).

32On the very first page of his introduction to the Didascalocophus, Dalgarno referred to his goal when publishing the Ars signorum some twenty years earlier, of ‘shewing a way to remedy the difficulties and absurdities which all languages are clogg'd with ever since the confusion, or rather since the fall; […] to cure even Philosophy it self of the disease of Sophisms, and Logomachies’.

33The literature on Wilkins's Essay is extensive. See, for example, Sidonie Clauss, ‘John Wilkins’ Essay Toward a Real Character: Its Place in the Seventeenth Century Episteme’, in Nancy Struever (ed.), Language and the History of Thought (Rochester 1995), pp. 27–49; Vivian Salmon, ‘”Philosophical” Grammar in John Wilkins's Essay’, in her The Study of Language in 17th-Century England, pp. 96–125; Van Leeuwen, The Problem of Certainty, esp. pp. 49–71.

40John Bulwer, Chirologia, or, the Naturall Language of the Hand: Composed of the speaking motions, and discoursing gestures thereof. Whereunto is added, Chironomia; or, The art of manual rhetoricke (London 1644). Bulwer also wrote a Philocopus, or the Deaf and Dumbe Mans Friend (London 1648) and a Pathomyotamia, or, A dissection of the significative muscles of the affections of the minde (London 1649).

41On Bulwer, see Rée, I See a Voice, pp.123–31.

42See Debus, Science and Education, pp. 33–64.

43Rée, in I See a Voice, gives a history of such attempts; see especially chs. 9–13 and references.

44Oliver Sacks, in Seeing Voices (London 1991), pp. 14–15, refers to a passage from the Cratylus (422d–423b) quoted by the Abbé de l'Epée, the official founder of sign-language in eighteenth-century France:

If we had neither voice nor tongue, and yet wished to manifest things to one another, should we not, like those which are at present mute, endeavour to signify our meaning by the hands, head, and other parts of the body?

45Dalgarno was the first to create a manual alphabet – dactylology – for the deaf, though John Bulwer preceded him in devising a complete sign language, or arthrologie, in his Chirologia and Philocophus (1648). For a brief account of the significance of Dalgarno, Bulwer, Holder and Wallis in the development of BSL (British Sign Language) see J. G. Kyle and B. Woll, Sign Language: The Study of Deaf People and their Language (Cambridge 1988), pp. 37–57.

48In this he followed Aristotle, De interpretatione, 16a3, citing his notion that ‘Words are the images of cogitations, and letters are the images of words’. See Bacon, Of the Proficience and Advancement of Learning, Divine and Humane (first published London, 1605), G. W. Kitchin (ed.) (London 1861; reprinted 1973), XVI, 1, p. 36.

A Name is a word taken at pleasure to serve for a mark, which may raise in our mind a thought like to some thought we had before, and which being pronounced to others, may be to them a sign of what thought the speaker had, or had not before in his mind. And it is for brevity's sake that I suppose the original of names to be arbitrary.

60See Shapin and Schaffer, Leviathan and the Air Pump, p. 92.

61For a discussion of Hobbes's views on the relationship between language and scientific knowledge, and on the ways in which they bear upon his understanding of scientific inquiry, see Douglas Jesseph, ‘Hobbes and the method of natural science’, in Tom Sorell (ed.), The Cambridge Companion to Hobbes (Cambridge 1996), pp. 86–107, especially pp. 96–102.

62Dalgarno, Didascalocophus, p. 18.

63Wallis, along with Seth Ward, was deeply hostile to Hobbes, and both Royal Society Fellows engaged in a heated debate with him that began after the publication of Hobbes's De corpore in 1650. For an analysis of the nature and significance of the conflict, and an account of the available sources, see Shapin and Schaffer, Leviathan and the Air Pump, esp. pp. 106, 126, 131–54, 311–12, 323–31.

On the definition and function of thought-experiments, see Shapin and Schaffer, Leviathan and the Air Pump, p. 55, n. 62, and Thomas Kuhn's ‘A Function for Thought Experiments’, reprinted in his The Essential Tension: Selected Studies in Scientific Tradition and Change (Chicago 1977), pp. 240–65, to which Shapin and Schaffer also refer and in which Kuhn analyses what kind of knowledge can be gained from thought-experiments.

67The theory needed to underpin such a notion was hardly available until the nineteenth century, but Hobbes, in Leviathan, pp. 103–4 (I.4), invoked the case of

a man that hath no use of Speech at all (such, as is born and remains perfectly deafe and dumb)’ to explicate the way in which, by imposing names, ‘we turn the reckoning of the consequences of things imagined in the mind, into a reckoning of the consequences of Appellations.

75Locke, Essay, II.xix.1.

76Locke was the first to try to recognise consciousness as a phenomenon that could be discussed and described, primarily in terms of personal identity. See Essay, II.xxvii.17.

77See Peter Dear, Discipline and Experience: The Mathematical Way in the Scientific Revolution (Chicago 1995), pp. 153–6, for an exposition of the same point.

78The notion of an evolved tendency was described, for example, by Kenelm Digby, who, in his popular pamphlet on the powder of sympathy, referred to a question he attributed to Plutarch, of whether horses run fast because the fastest horse escapes from the wolf at his heels. See A Discourse made in a Solemne Assembly of Noble and Learned Men at Montpellier in France, by Sir Kenelme Digby, Knight &c., Touching the cure of wounds by the powder of sympathy, 2nd edn (London 1658), pp. 2–3.

84Ibid., p. 2. In his Panégyriqe de Sainte Catherine (Paris 1660), Bossuet (1627–1704) wrote that women should avoid acquiring solid scientific knowledge not because it was beyond their means, but because doing so would be ‘une épreuve trop dangereuse pour leur humilité’. See L'éducation des filles in Fénelon, Œuvres, ed. by Jacques Le Brun (Paris 1983), I, p. 1271, n. 5.

87On the history of reactions to Cartesianism see, for example, Albert G. A. Balz, Cartesian Studies (New York 1951) and the useful collection by Vere Chappell (ed.), Essays on Early Modern Philosophers: Cartesian Philosophers (New York 1992). See also John Sutton, Philosophy and Memory Traces: Descartes to Connectionism (Cambridge 1998), esp. chs. 5–9.

93The distinction between a ‘language of thought’, in the sense coined by Jerry Fodor in Language of Thought (Cambridge, Mass. 1975), and grammatical language is of course not new and goes back to Plato. In Leviathan, towards the beginning of I.3, Hobbes explicitly differentiated a ‘mental discourse’, which he assumed animals possessed as well as humans, from the ‘discourse in words’ established by humans themselves. He made a congruent point in De homine (1658), X.2: Traité de l'homme, ed. by Paul-Marie Maurin. (Paris 1974), p. 144: Adam chose to taste the tree of knowledge before there was any language in which God's entreaty could be expressed.

94Cordemoy was another friend of Bossuet and from 1673 a ‘lecteur ordinaire’ to the Dauphin; he was elected to the Académie française in 1675. He was an esteemed member of the Cartesian circles fashionable in Paris in the 1660s, around Mme de Bonnevaux, Henry Louis Habert de Montmort, Jacques Rohault, Guillaume de Lamoignon, the abbé Bourdelot, and Lefèvre d'Ormesson. For a full account of Cordemoy's life, see the ‘Introduction’ to Gérauld de Cordemoy, Oeuvres philosophiques, avec une étude bio-bibliographique (Paris 1968), Pierre Clair and François Girbal (eds).

98Cordemoy, Discours physique de la parole, in Oeuvres, p. 206 (‘Preface’).

99Aristotle, De interpretatione, 16a3. Cited in K. O. Apel, ‘The Transcendental Conception of Language: Communication and the Idea of a First Philosophy’, in H. Parret (ed.), History of Linguistic Thought and Contemporary Linguistics (Berlin and New York 1976), p. 36. Bacon cited the same Aristotelian passage for this fairly straightforward notion. Cordemoy does not seem to have been referring explicitly to Aristotle but the analogy is evident enough.

101Ibid., p. 196.

Everson (ed.), Companions to Ancient Thought, 3: Language (Cambridge 1994), pp. 129–48. See also Elisabeth de Fontenay, Le silence des bêtes. La philosophie à l'épreuve de l'animalité (Paris 1998).

106See Descartes, letter ‘Au Marquis de Newcastle’, 23 November 1646 in Descartes, Œuvres, Alquié (ed.), p. 694.

107 Discours, in Œuvres, p.196 (‘Preface’).

108Ibid., p. 206.

109Ibid., pp. 223–33. According to Cordemoy, the acoustic processes which allowed animals to hear each other were identical to those in humans insofar as speech was also a purely physical activity which did not on its own, or a priori, entail a soul.

110Ibid., p. 209. Cordemoy posits an equivalence between the relation of word to thought and that of animal, machine or rock to man: see Philippe-Joseph Salazar, Le culte de la voix au XVIIème siècle: Formes esthétiques de la parole à l'âge de l'imprimé (Paris 1995), p. 73; on Cordemoy, pp. 71–7.

111Ibid., p. 210.

112Ibid., p. 208.

113Ibid., p. 233.

114See Noam Chomsky's suggestive talk, published, along with the ensuing discussion, as Language and Thought (Wakefield and London 1993), p. 37, in which he briefly refers to this test, devised by Cordemoy (and other Cartesians, as well as Descartes himself) for ‘determining whether another object has a mind like ours’, as ‘normal, garden variety science, like developing a litmus test for acidity: the task is to determine whether one of the real components of the world is present in a certain case – acidity, or a mind’.

115Cordemoy, Discours, in Œuvres, pp. 233–4.

116Chomsky, Language and Thought, pp. 37–40, also points to the possibility of comparing the ‘Cartesian tests for the existence of other minds with the current reliance on the 1950 “Turing test” to determine “empirically” whether a machine can carry out some intelligent act (say, play chess)’. But he then speaks of a ‘conceptual regression since the cognitive revolution of the 17th century’ and argues that one should not submit the study of the mind to a rigidly defined field and set of methods.

119Ibid., pp. 250–3. See also the ‘Preface’, p. 199.

121For an insightful analysis of the place of Cordemoy's thought on language in his metaphysics, see the essay by Balz, Cartesian Studies, pp. 3–27: ‘Geraud de Cordemoy 1600–1684’.

122Cordemoy developed the notion that we might be mistaking occasion for cause in his Six Discours sur La distinction & l'union du corps & de l'ame, first published in 1666.

123Cordemoy, Discours, in Œuvres, p. 29. See also Hans Aarsleff, ‘Descartes and Augustine on Genesis, language, and the angels’, in Marcelo Dascal and Elhanan Yakira, (eds), Leibniz and Adam (Tel Aviv 1993), pp. 169–95, at p. 175.

124Aristotle, in De anima, II, 8, 420b, describes the human voice as an animal sound produced by the impact of air on the trachea along with an image. See Salazar, Culte de la voix, p. 31.

128First published posthumously in Paris in 1664, but written as a companion treatise to L'Homme, which itself was first published at Leiden in 1662, in a Latin translation, and, again by Clerselier, in Paris, in the original French in 1664.

130Ibid., p. 315.

131Hacking, in Why does Language, p. 23, shows how Hobbes, despite having a definite notion of language, ‘did not have a theory of meaning’ (Hacking's italics). Precisely because thought and language were not construed as interdependent, the concept of meaning was not supervenient on the analysis of the linguistic function. See also Chomsky, Language, pp. 22 and 59 (the observation by Eric Wanner).
