Differentiation (linguistics)

Differentiation in semantics is defined by Löbner (2002) as a meaning shift reached by "adding concepts to the original concepts". His example is James Joyce is hard to understand, where understand is differentiated from "perceiving the meaning" to "interpret the text meaning".

A related meaning shift is metonymy, where one builds a new concept out of an element of the original concept. In the example mentioned, James Joyce most likely refers to "the work of James Joyce" and not to the author - a metonymical shift. If the name were to refer to the man, understand would be differently differentiated, perhaps one would read it as "interpret the speech articulation" or "comprehend the actions" of the person James Joyce.

Meaning shifts are very common among language users, and allow for great flexibility of word usage. It is not to be confused with lexical ambiguity though, words as uttered in a context may have perfectly precise meanings even though in varying contexts they may be used to express widely different meanings.

Differentiation (sociology)
See articles: sociology, sociological theory, social theory, and system theory

Differentiation is a term in system theory (found in sociology.) From the viewpoint of this theory, the principal feature of modern society is the increased process of system differentiation as a way of dealing with the complexity of its environment. This is accomplished through the creation of subsystems in an effort to copy within a system the difference between it and the environment. The differentiation process is a means of increasing the complexity of a system, since each subsystem can make different connections with other subsystems. It allows for more variation within the system in order to respond to variation in the environment. Increased variation facilitated by differentiation not only allows for better responses to the environment, but also allows for faster evolution (or perhaps sociocultural evolution), which is defined sociologically as a process of selection from variation; the more differentiation (and thus variation) that is available, the better the selection. (Ritzer 2007:95-96)

Usage examples of "differentiation".

Heterarchy, in and by itself, is merely differentiation without integration, disjointed parts recognizing no common and deeper purpose or organization: heaps, not wholes.

This directionality is usually stated as being one of increasing differentiation, variety, complexity, and organization.

Complexity thus emerges from the interpenetration of processes of differentiation and integration.

Whenever a new differentiation is not matched by a new and equal integration, whenever there is negation without preservation, the result is pathology of one sort or another, a pathology that, if severe enough, evolution sets about to erase in earnest.

Whenever evolution produces a new differentiation, and that differentiation is not integrated, a pathology results, and there are two fundamental ways to approach that pathology.

This approach, in my opinion, simply confuses differentiation and dissociation, confuses transcendence and repression.

By that retro-Romantic logic, the only way to really get rid of pathology is to get rid of differentiation altogether, which means everything after the Big Bang was a Big Mistake.

Thus, on level 1, or A, we already find dissipative or self-organizing structures, holons with depth and span, creative emergence, increasing complexity, evolutionary development, differentiation, self-transcendence, teleological attractors, and so forth.

That this differentiation went too far into dissociation is a topic we will discuss in chapters 12 and 13.

To automatically assume that differentiation of roles is the result of domination is to automatically define a particular group as victim, which automatically and irrevocably disempowers that group in the very attempt to liberate it.

But where the differentiation of the biosphere and the noosphere was not complete, the biospheric identities sucked these movements back out of the noosphere and into the bodily or biological determinants.

To the world of appearance belongs all differentiation, all generation and destruction, all motion and change, whereas the Truth is as it is, perfectly self-existing, and not open to any differentiation or distinctions of any sort.

Being in itself, prior to differentiation and prior to the Way of Appearance.

And the dialectic was in part a way to directly point to reality prior to its differentiation and illusory appearances, in which mortals become lost because they mistake these appearances for the undivided Truth.

The differentiation of the Big Three can be criticized, but the criticism itself presupposes the differentiation.
