Consciously or not, the purpose of all human sciences is significations. Accordingly, all lessons ought to be learned from hermeneutics, as it is the science of interpretation. Whether we are interpreting texts or behavioral conduct, we use the same methods and we face the same difficulties. The history of hermeneutics has continuously clarified the dimensions of symbolic facts which constitute the purpose of interpretation, namely: the neutral aspect of textual configurations, the poetic aspect of production strategies and the aesthetic aspect of reception strategies. Hermeneutics is a semiology, but semiology is also a hermeneutic. Both should merge into one theory of symbolic forms inspired by Percy; which alone could transcend the traditional intellectual impasse of hermeneutics and the uncertainty of semiology.
