In contemporary society, we make use of the notion that things may be synthetic. Thus we may speak of synthetic biology, “synthesizers” (synthetic sound), synthetic textile etc. Such things are supposed to be artificial and not come from “nature”.
However, the Greek root of the word synthesis actually seems to refer to the conjoining of pre-existing things, rather than something being purely man-made. But what does it mean to be purely man-made?
Furniture, bricks, bottles, roads and bread are all made in some sense; they are the result of human methods, tools and craft applied to some substrate. But they do not ever lose the character of the original substrate, and usually this is the point – we would like to see the veins of wood in fine furniture, and when we eat bread, we would like to ingest the energy, minerals and other substances that are accumulated in grains of wheat.
Products like liquid nitrogen or pure chlorine, created in laboratories, are perhaps the ones most readily called “synthetic”, or the ones that most readily would form the basis for something synthetic. This owing to their apparent lack of specific character/particularity, such as the veins of wood or the minerals in wheat. On the other hand, it is apparent that they possess such non-character only from the point of reference of atoms as the lowest level. If we take into consideration ideas from string theory or quantum mechanics, most likely the bottom level shifts and the pure chlorine no longer seems so homogenous.
Accordingly, if we follow this line of thought to the end, as long as we have not established the bottom or ground level of nature – and it is questionable if we ever shall – all manufacture, all making and synthesis, is only a rearrangement of pre-existing specificity. Our crafts leave traces in the world, such as objects with specific properties, but do not ever bring something into existence from nothing.
Synthesis is appropriation: making is taking.
