It is now generally acknowledged that argumentation is only
possible when there is a shared framework. As Wittgenstein pointed
out, to have agreement in opinions, there must first be agreement on
the language used. But he also alerted us to the fact that those
represented 'not agreement in opinions but in forms of life'.

In his
view, to agree on the definition of a term is not enough and we need
agreement in the way we use it. As he puts it: 'If language is to be a
means of communication there must be agreement not only in
definitions but also (queer as this may sound) in judgements.'
