Relationship between epistomology, moral of scepticism and form of life according to Cavell's Wittgenstein

According to Cavell, on one hand relation between moral values and the reality based on the grammatical criteria of Wittgenstein is not rational; on the other hand, disability of moral criteria is not logical .From this point of view, the claim of having access to the pure reality is meaningless, because there is not a logical possibility of such success that one can or cannot do it. In other words, we don't have the natural possibility for having a logical and rational way to solve moral problems. Therefore moral issues are not rational.From the view of Cavell’s Wittgenstein, meaning is appearing during using language game inside its form of life. So, in the process of responding to an ethical request, Wittgenstein's human, responds to the reality in certain situations, depending on the conditions, with the intention and moral judgment, Thus from his view point, before using words in moral language games, we do not have meaning.
