Enworldment is my preferred term for lifeworld. I think it’s prettier and it has some desirable overtones: enworldment sounds like something that we intentionally shape for ourselves, where one can easily imagine an amoeba inhabiting a lifeworld.
Enworldments are held together by conceptions. Conceptions manifest in a variety of ways — only one of which is language.
Language is undoubtedly one of the most important manifestations of conceptions. Language provides our best access to conceptions, our readiest way to share them and also our best means to change them — to interrogate them, weaken them, break them, and to find novel conceptions, entertain alternative ones, to evaluate them and to adopt new conceptions in place of old ones.
Because language is so closely connected with conception it is easily to reduce conceptions to language or reduce change of conceptions to a change of language. To to conflate or confuse conceptions with verbalized concepts is to commit a logocentric category mistake.
Why should anyone care about avoiding this mistake? Changes in conception have consequences that extend beyond language. For instance, changes in conception can affect perception, not only in how a perception is interpreted (such as learning to see an optical illusion) but even how it is experienced aesthetically (such as when we acquire a taste, or when our tastes change in response to changes in our lives).
This should not be surprising if you understand perception as sensory conception (sensorily taking-together). A painter’s or musician’s style manifests conceptions in visual or auditory form, and a style resonates with us when we receive it via analogous conceptions, or they intrigue or disturb us when we intuit a conception that we are on the edge of learning.
From here I want to develop the idea that these conceptions we use to enworld ourselves and make sense of, interact with and to value some things at the expense of other things is not something we only do to enable us to change our world — though it does do that. The enworldment itself transfigures the world even before we apply it to our actions, in ways that make some better than others for different people in different contexts.
