Contemporary discussions of the fruitful concept of form of life have made it possible to highlight the extent to which the concept of form itself is essential in the work of Wittgenstein, structuring the continuity between the early and later Wittgenstein. In moving from “logical form” to the concept of form of life, Wittgenstein intends to give up the unity of “form” in order to turn to a “family” of related structures. But logic does not disappear—on the contrary. The point on which his research is based is still form, understood now as a plurality of ways for language to describe reality. It is therefore essential to understand the concept of form (of life), Lebensform, not only as an alternative to the concept of rule but as an expression of a new understanding of form.
