“As the renovator of scientific inquiry, Francis Bacon was only marginally interested in perfect languages. Yet, marginal though they may have been, his remarks on the subject have a notable philosophic interest.
A central theme in Bacon’s works was the destruction of idola, that is, false ideas arising either from human nature, collective or individual, or from philosophical dogmas handed down by tradition, or else–and this is what interests us the most–from the way we use language itself (idola fori).
Such linguistic usages have been determined by the needs of common people, so disturbing our way of reasoning (Novum organum, I, 43), and the idola that common speech imposes are either names for non-existent things, or confused, ill-defined and partial names for existing things (Novum organum, I, 60).
An example of a confused notion is that of the moist: this may signify a great variety of things; it can mean that which spreads rapidly around another body, that which is devoid of cohesion and consistence, that which is easily moved in whatever direction, that which can be divided and dispersed, that which can easily be reunited and gathered up, that which attaches itself easily to another body and moistens it, that which easily passes into a liquid state and dissolves.
To speak scientifically means thus to implement a speech therapy.
The idea of a linguistic therapy was a recurrent theme in Anglo-Saxon philosophy. In the Leviathan (1651: IV), Hobbes noted that there are four main uses of speech,
“…First, to register, what by cogitation, wee find to be the cause of any thing [ . . . ] Secondly, to shew to others that knowledge which we have attained [ . . . ] Thirdly, to make known to others our wills, and purposes [ . . . ] Fourthly, to please and delight our selves, or others, by playing with our words, for pleasure and ornament, innocently.
To these uses, there are also foure correspondent Abuses. First, when men register their thoughts wrong, by the inconstancy of the signification of their words [ . . . ] Secondly, when they use words metaphorically [ . . . ] Thirdly, when by words they declare that to be their will, which is not. Fourthly, when they use them to grieve one another.”
In the third book of the Essay concerning Human Understanding, Locke observed that:
“For since Sounds are voluntary and indifferent signs of any Ideas, a Man may use what Words he pleases, to signify his own Ideas to himself: and there will be no imperfection in them, if he constantly uses the same Word for the same Idea [ . . . ] The chief End of Language in Communication being to be understood, words serve not well for that end [ . . . ] when any Word does not excite in the Hearer, the same Idea which it stands for in the Mind of the Speaker.” (III, IX, 2, 4).
For Bacon, signs might be of two types. Signs ex congruo (we would say iconic, motivated)–like hieroglyphs, gestures or emblems–reproduce in some way the properties of the things they signify; signs ad placitum are arbitrary and conventional.
Yet even a conventional sign can be defined as a “real character” when it refers not to a sound, but directly a corresponding thing or concept.
Bacon thus speaks of “Characteres quidam Reales, non Nominales; qui scilicet nec literas, nec verba, sed res et notiones exprimunt” (De Augmentis Scientiarum, VI, 1). In this sense, the signs used by the Chinese are real characters; they represent concepts without, however, bearing any similarity to the signified objects.
We see here that, unlike Kircher, Bacon was unaware of the vague iconism of Chinese ideograms; this, however, was a misapprehension that Bacon shared with a number of other contemporary authors.
Even Wilkins commented that, beyond the difficulties and perplexities that these characters generated, there seemed to be no analogies between their forms and the forms of the things that they represented (Essay, 451).
Probably Kircher had the advantage of knowing the direct reports on Chinese culture of his fellow Jesuits, and was thus able to form a clearer picture of Chinese ideograms than English scholars forced to rely on indirect accounts.
For Bacon, then, Chinese ideograms were examples of signs which, though arbitrary and conventional, stand directly for a signified notion without the mediation of a verbal language. He remarked that, even though the Chinese and the Japanese spoke different languages and thus called things by different names, both recognized them by the same ideograms, and, therefore, could understand each other by writing.
According to an example by Lodwick, if we propose to denote the sky with a 0, such a real character would be distinct from a vocal character…
“…in that it signifieth not the sound or word “heaven” but what we call heaven, the Latin coelum etc., so that the carracter being accepted will by the English be read heaven without respect to what the Latin would name the same thing [ . . . ] A frequent instance hereof we have in the numerical carracters (sic) 1.2.3., which signify not the severall sounds by which the severall (sic) nations in their severall languages expresse (sic) them but that common notion wherein those severall nations agree as to them (MS Sloane 897 f32r; in Salmon 1972: 223).”
Bacon did not think that a character supplied the image of the thing or revealed its intrinsic nature; his characters were nothing other than a conventional sign which, however, referred to a clear and precise notion.
His problem, then, became that of formulating an alphabet of fundamental notions; his Abecedarium novum naturae, composed in 1622, which was to appear as the appendix of the Historia naturalis et experimentalis, represented an attempt to make an index of knowledge, and was not connected to any project for a perfect language (see Blasi 1992: Pellerey 1992a).
Later attempts were none the less inspired by the fact that Bacon decided to associate Greek letters with every item of his index, so that, for example, α meant “dense and rare,” ε “volatile and fixed,” εεεε “natural and monstruous (sic),” οοοοο “hearing and sound.”
