Antoine Destutt de Tracy: Elements of ideology, First part, Ideology in the proper sense (1804)

(1754-1836)

Destutt de Tracy is a figure I should have considered far earlier. His influence especially on Maine de Biran’s philosophy is remarkable, but even Ricardo borrowed a few quotations from his work. His probably most important work, Élémens d'idéologie, was originally meant as a textbook for the growing citizens of revolutionary France. The work and especially it first part on Idéologie proprement dite was intended as a sort of theory of theories, that is, a kind of methodological bedrock, upon which all the other sciences could be founded.

The name of the science, which Destutt de Tracy supposed to have found, ideology, refers back to Lockean term “idea”, which described the elements of human mental life - ideas was whatever we happened to have in our minds while thinking something. Thus, the primary question of this science of ideology, for Destutt de Tracy, was what we do when we happen to think. His simple answer was that all thinking was actually sensing, where sensations could be had not just of things outside us, but also of our own internal states. In a sense, one can undoubtedly ascribe to this idea - if by sensing we mean being aware or conscious of something, certainly when we are pondering something, we are conscious or aware of this something. The major unanswered question is whether this description merely loses some essential differences within our mental life - that is, whether being conscious of what lies in front of our eyes isn’t quite different from being conscious of, say, memory of what lied before my eyes yesterday.

Indeed, de Tracy himself admits as much, when he divides sensations into four different species: sensations proper, memories, judgements and volitions. Still, even here we find that de Tracy emphasises more their unity than their diversity. Firstly, he quite correctly points out that these four types rarely occur in isolation, but an individual experience is often a combination of many sorts of sensations - when we perceive an apple, we may also remember the taste of other apples, judge that the taste of an apple would be pleasant and desire to eat this particular apple. Secondly, de Tracy constantly emphasises that even memories, judgements and volitions are still just sensations. This insistence makes de Tracy’s idea of judgements and volitions especially peculiar. Judgements, he says, are nothing but sensations of agreement between other sensations or ideas. That is, judgement is not an active assertion of such an agreement, but just a passive perception of it. Similarly, volition is not for de Tracy an act of wanting something, but merely a passive perception of a need.

De Tracy appears to be quite oblivious of the possibility of describing mental life as consisting of acts rather than through mere concept of awareness. This ignorance might well be behind his opinion that all other supposed species of thinking or mental life reduce to the four basic types. For instance, attention is, according to de Tracy, no independent form of sensation, since it is just quantitatively differentiated sensation proper, in which some part of a sensation has greater vividness than other parts. Or deduction is on his opinion just a concatenation of many judgements. One might object that attention is quite a different act from mere perception or sensation - it is an active concentration on some part of sensation - while reasoning or deducing is quite a different act than mere judgement - it is an act of justifying one judgement through others.

Despite de Tracy’s rather passive notion of sensation, he does not completely forget the active side of human being. Instead, he speaks of active muscular movement as the other necessary ingredient of human life. This muscular movement is peculiarly connected with the type of sensations called volition - when we move voluntarily, we feel both a desire to move in a peculiar manner and at the same time the actual activity of our muscles. This combination forms our sense of self. On the other hand, when we feel that our movements are hindered, we conclude at once that this hindering is caused by another existing thing. Our activity is then our only link to the existence of other things.

Since the existence of other things is revealed especially through movement, de Tracy takes them to be especially characterised through attributes relating to movement. They can be moved, but they also resist attempts to be moved, and together these two features imply that they can also impart movement to other things. Space and time are then in a sense abstractions from movement. Duration is generally something pertinent to all processes, including movement, and duration becomes time, when we choose one type of movement - for instance, apparent movement of the sun around earth - for measuring how long some processes take. Distances are compared according to how long it takes us to traverse them with a constant effort, and when similarly a scale of measure is applied to them, we get a metric space. Because all things we can experience have limits in space, we get different shapes and can do basic geometry.

Something which Maine de Biran was to investigate was more detail was the influence of habit to our different mental faculties. Still, we can find some basic details of Maine de Biran’s theories already implicit with de Tracy. Habit makes mental activities easier and at the same weakens the vividness of the sensations - we can do more, but we are less aware of doing it. Indeed, one might ask if in this description de Tracy is implicitly accepting the idea that mental acts are something completely different from mental awareness and that both are necessary ingredients of human mental life.

The final chapters of de Tracy’s work provide a link to the following parts of Ideology. He investigates the use of signs in general and language in particular. De Tracy notes that we have a sort of natural language, consisting of gestures and interjections. Yet, it is only a proper language, in which the use of sounds and inscriptions is codified, that lets us truly think beyond some simple sensations - for instance, we couldn’t really understand mathematical truths, unless we could speak of units and their sums. But this is already more appropriate topic for de Tracy’s next book on grammar.
