(Non)cognitive Aspects of the Notebook: Extended Cognition and Practice of Use

Abstract

In the first part of the article the basic characteristics of the hypothesis of extended cognition (HEC) are briefly sketched, as well as some problems and objections to this hypothesis. The second part points to affiliations between the hypothesis and Wittgenstein's approach to problems of mind. According to the argumentation presented here, Wittgenstein's position leads to the claim that there are cases in which an external object, along with activity of the organism, are necessary elements for the fulfilment of a cognitive task. Also, Wittgenstein's approach can be helpful as a response to objections to HEC concerning the scope of the cases which can be marked as extended cognition. This approach proceeds from activity, practice of use or acquired technique as the main basis for the determination of the characteristics and the criteria of external cognition.
