Antoine Destutt de Tracy: Elements of ideology, Third part, Logic (1805)

The main feeling after reading the third part of Destutt de Tracy’s magnum opus is one of futility - why did he have to write the book or at least why did he have to use so many pages for it? The main point of the work is so simple and could have been said in far fewer words.

Destutt de Tracy’s first point is that traditional logic has followed a completely misleading route. The aim of logic should have been to find the ultimate reasons why we sometimes stumble into error and methods for avoiding such errors. After Aristotle had put so much effort in classifying the various species of valid syllogisms, every logician was under the impression that these rather quaint formulas were the essence of logic, although they were sterile and quite useless in producing new truths.

Destutt de Tracy’s second point is that the true source of certainty can actually be found in the two previous parts of his ideology. All human thinking is just sensation, and in a sense, all sensations are as such reliable. Although this might appear rather far-fetched, Destutt de Tracy’s point appears to be simply that when we sense or experience something, we are certainly having that experience and something either outside or inside us is making us experience things in that manner. This means especially that simple sensations of things present are a completely reliable source of knowledge - if we sense red, then we are sensing red and something is making us sense red.

An error comes into the picture only with judgement. There’s no question about it that we sense red and that something makes us see red, but the question is can we say what this red-sensation-making thing is and whether it is even an object outside us or just some hallucination inducing state within us - or, to take another object, if we see a crooked stick, whether this sensation of crookedness is caused by a truly crooked stick or by a straight stick together with the refraction of water.

Now, judgements are also, Destutt de Tracy said, sensations - they are experiences of one idea being connected to another idea. Thus, there is no particular reason why judgements as such couldn’t be as reliable as ordinary sensations. For instance, if we note that a certain sensation must be produced by an external object, because it resists our efforts to change it, we can be fairly certain that this judgement is reliable.

The reason making certain judgements unreliable, Destutt de Tracy suggests, is essentially our bad memory. We have a sensation and are convinced that this sensation resembles sensations we used to have. If our memory of these earlier sensations were faulty, we would then be in error. Since all our general concepts are just abstractions from earlier sensations, according to Destutt de Tracy, this source of error can easily cause much damage in our cognitive state.

“Base your knowledge on present sensations and try to avoid faulty memories” is then the simple answer to most questions of logic - Baconian empiricism is the solution to everything. The only other thing we need to take into account is the role of language, since most of our cognitive processes happen through words. Indeed, when we learn things just through reading - a favourite point of ridicule, of which scholastics used to be accused - we are just having sensations of certain signs, which have the ability to induce in us some ideas, although these ideas might have no resemblance with our direct sensations. Language is thus another possible source of misinformation, but it is also a possible source of correct information, as long as we just know the semantics of the language used.

And this was it! No further methodology is required, Destutt de Tracy appears to say, and a more cynical reader might ask if experience and semantics is truly enough for finding new truths, although they are undoubtedly good tools for avoiding errors.

Apparently just to add some more pages to his book, Destutt de Tracy chose to give a general outline of what his ideology should contain. Despite its supplementary nature, this is by far the most interesting piece of the work. The three books Destutt de Tracy had published thus far formed only the first third of the whole ideology, or in more detail, the part dealing with human cognitive capacities. Even in this part Destutt de Tracy had noticed that human beings had something beyond mere cognition or sensations, namely, active drives, which we sense as volitions. The second part of ideology should then be formed by the study of our volitional side. Since this part of ideology Destutt de Tracy managed to at least partially publish, I shall not handle it now.

The third planned, but never published part should have then dealt with things external to humans. As we saw already with the first part of Ideology, Destutt de Tracy thought our belief in things external to us was based on our volition and especially on the feeling of resistance we have, when we are prevented from getting what we want. This resistance and its various kinds form then in Destutt de Tracy’s view the basis on which physical sciences would have to be founded.

In addition to physical sciences and concrete bodies, this third part of ideology would deal with the abstraction of distance, which we measure with our movement. Thus, we get the ideas of spatial dimensions and shapes, which form the topic of geometry.

Finally, the third part would have to deal with the imaginary world of numbers, which we create from the abstraction of units and an imagined collections of such units. On basis of this simple beginning can be built more and more complex ways to manipulate numbers, which retain their certainty because of their connection with these original notions of unit and addition and because of precision involved in mathematical language. Despite this world of numbers being completely imagined, Destutt de Tracy said, it could be used in real world, just because and when we could find suitable items to take as units.

Next time, we shall see the conclusion to the story of ideology.

Antoine Destutt de Tracy: Elements of ideology, Second part, Grammar (1803)

Although second part of Destutt de Tracy’s grand work is supposedly about grammar, it is more a book about language in general. Thus, it contains, among other things, an account of the genesis of language. Destutt de Tracy thinks that human beings come with a natural language, consisting of cries, signs and tactile impulses. One might find here a delightful admission that a language need not be aural, but could be something like a sign language or Braille writing. Yet, Destutt de Tracy does not really develop the implications of this idea and considers only speech as a fixed and conventionalised modification of the original language of action

In a quite believable manner Destutt de Tracy considers the original speech to consist of individual expressions indicating whole sentences, somewhat like a child could cry “Milk”, when she wanted to drink milk. The development of language means then a sort of analysis of parts implicit in these original interjections. First, Destutt de Tracy says, language users differentiated a subject from verb, making subject-verb the general form of all language. Here, subject indicates an existing thing and verb signifies its mode of existence (e.g. “Bob runs” says that a thing indicated by the name Bob exists runningly). With the invention of the general and neutral verb “being”, it is possible to abstract attributes or adjectives, which are otherwise like verbs, but lack the idea of existence. Further developments include the introduction of more complex noun and verb forms through the use of prepositions and the capacity to subjunct sentence to other sentences with the general conjunction “que” (that) and later with other, derivative conjunctions.

One can see from this short summary of Destutt de Tracy’s account of grammar that he is engaging in a sort of attempt at universal grammar in the fashion of Chomsky. As with Chomsky, the problems in Destutt de Tracy’s account are evident when one looks beyond the restricted number of languages he considers. One can e.g. argue that subject-verb is not the general form of all sentences (indeed, there are languages, in which subject is not required at all and one might insist that in sentences like “It rains” there is no real subject) and that verbs do not always convey the idea of existence (like when one is discussing fictional things).

It is not just the generation of grammar in speech Destutt de Tracy considers, but also the generation of written signs representing speech. It had been a pet idea of 18th century thinkers like Leibniz that a system of ideogrammatic symbols, like Egyptian hieroglyphs or Chinese characters, which represented complete ideas, would be a perfection of written language, since it would allow turning language into a direct calculation. By the beginning of 19th century, this idea had lost its charm, since ideograms were so obviously difficult to work with. Destutt de Tracy considered them to have a stunting effect to a culture of a nation - ideograms formed a sort of second language, which required years of learning and the use of which was thus restricted to a certain class.

Destutt de Tracy was thus convinced that phonogrammatic symbols, like regular alphabets, which represented sounds of speech, were more suitable for development of sciences. Still, he did not believe that alphabets would have developed out of hieroglyphs - so certain he was that a culture with ideogrammatic writing could invent anything. Instead, he regarded alphabets as an alternative line of development. While hieroglyphs were invented for the purpose of expressing ideas, Destutt de Tracy insisted, alphabets were invented for the sake of music, which required signs by which to indicate different sounds in singing. Although a rather beautiful idea, it is most certainly quite false, since e.g. Hebrew alphabets were a direct development out of Egyptian hieroglyphs.

Just like Destutt de Tracy appeared to dream of a universal grammar, he was also keen on finding a universal alphabet, which would be able to represent all kinds of sounds used in human languages. It doesn’t require much consideration to notice how utterly unmanageable as a practical writing tool such a universal phonetic system would be. Indeed, when one looks at phonology of a single language, one sees how utterly confusing it might even be - a single language doesn’t use all possible sounds humans can produce, and in fact, some sounds are alternatives, which to a language user sound just like arbitrary variations of the same sound (phoneme, in technical terms).

Destutt de Tracy actually isn’t so bold as to suggest that all languages in the world should start to use a phonetically perfect alphabet, because he knows that such innovations would not be easily accepted by the majority of language users. Indeed, even a more modest attempt to turn the writing of a given language into phonologically perfect terms, in which one phoneme were represented by a single letter, might be quite difficult to achieve. In fact, what Destutt de Tracy suggests is to use this phonetic writing as a tool for language learning - if words were written with such phonetic signs, one could instantly know how to pronounce a word of foreign language. Of course, even this is a bit too idealistic notion - even phonetic signs don’t teach you to actually pronounce the required sounds, let alone make speaking a language completely natural.

On the whole, Destutt de Tracy is critical of any idea to artificially construct a more perfect language, in which one could just calculate what connections of ideas are true - another pet idea of Leibniz. Destutt de Tracy admits that such a language can exist in a limited setting, such as algebra, but it could never form a complete and living language. Even if one would be able to overcome the resistance of the common people, one would still face a great obstacle. The very structure of thinking varies widely from one person to another and there is no guarantee that two different persons would have even remotely similar ideas of the same things. Thus, in building a perfect language, one would not have any single system of ideas to represent. Indeed, the best one could do in aiding thinking was to cultivate a science of good thinking or logic - the topic of the next part of the series.
