Instead of describing the theory in abstract form, we shall begin by considering some concrete examples. Take, for instance, the English word ‘weed’. One dictionary defines this word as 'wild herb springing where it is not wanted’, in short, an undesirable, unwanted herb. Now in the world of objective reality, that is, in the realm of nature, there is no such thing as an 'undesirable’ herb; such a thing can exist only in the sight of man, who looks at the infinite complexity of natural objects, puts them in order, and evaluates them in accordance with his various purposes. The concept of 'weed’ is the result of such a process of ordering, sorting out, evaluating, and categorizing. It embodies, in this sense, a particular point of view, a particular subjective attitude of the human mind.
The common-sense view simply and naively assumes the existence of a direct relationship between words and reality. Objects are therein the first place, then different names are attached to them as labels. In this view, the word 'table’ means directly this concrete thing which exists before our eyes. But the example of the word 'weed’ clearly shows that this is not the case; it shows that between the word and the thing there intervenes a peculiar process of subjective elaboration of reality. Our minds not only passively reflect the structure of reality, but more positively look at reality from a particular point of view, a particular angle; and it is this mental activity, which the Germans call Geist, that makes the thing really exist for us. There is a certain act of creativity, an elaboration of the given material in a certain direction, between reality and language. And that precisely is the proper domain of Meaning. In modern terminology, this may be expressed by saying that each word represents a particular linguistic categorization of nonlinguistic reality. But categorization necessarily implies the mental process of gathering many different things into a unity, and this is only possible on a certain principle. This principle is the particular angle from which man approaches reality, and it is conditioned culturally and historically.
