World disclosure

World disclosure (German: Erschlossenheit, literally development or comprehension) refers to how things become intelligible and meaningfully relevant to human beings, by virtue of being part of an ontological world – i.e., a pre-interpreted and holistically structured background of meaning. This understanding is said to be first disclosed to human beings through their practical day-to-day encounters with others, with things in the world, and through language.

The phenomenon was described by the German philosopher Martin Heidegger in his landmark book Being and Time. It has also been discussed by philosophers such as John Dewey, Jürgen Habermas, Nikolas Kompridis and Charles Taylor.

Some philosophers, such as Ian Hacking and Nikolas Kompridis, have also described how this ontological understanding can be re-disclosed in various ways (including through innovative forms of philosophical argument).

The idea of disclosure supposes that the meaning of a word or thing depends upon the context in which we encounter it, including the way of life of which it is a part. For example, a table is part of a context with other things that give it its sense or purpose – e.g. chairs, food, a teapot, pencils, books – and we first learn about it through our everyday experience of it in particular contexts. Its meaning is "given" to us by virtue of its connection to various activities (e.g. writing, eating, conversation), and by qualities (e.g. conviviality) that give it value in relation to such activities. These constitute part of its "conditions of intelligibility."

The implication is that we are always already "thrown" into these conditions, that is, thrown into a prior understanding of the things which we encounter on a daily basis – an understanding that is already somewhat meaningful and coherent. However, our understanding cannot be made fully conscious or knowable at one time, since this background understanding isn't itself an object:
