On 22 May 2014, he held his emeritus lecture about the Jewish roots of the philosopher Ludwig Wittgenstein. Philosophy. By September 2004 he had published around thirty articles; primarily about language (analytical) philosophy, in particular in relation to Wittgenstein, and about philosophy of mind. Many of his publications focus on the problem of the free will. Leilich has dealt with the question of the rationality of pragmatic explanatory frameworks for the use of words. As such, he discovered that this  ability for humans to justify the use of language, with regards to its normative aspect, is a fundamental expression of human reasonableness. Leilich has argued that nature is neither evil nor good, since moral proclamations require the involvement of mind to be appropriate. He has also been noted for making practical assertions as to what philosophy can mean to society, drawing upon the ideas of Peter Bieri, and has reflected upon the arising of new branches of science during popularizing lecture series. Further more he has investigated the mental processing of sensory stimuli. Bibliography. Compilations. Leilich compiled a collection of  letters by Ludwig Wittgenstein, translated by Hans Driessen. The compilation of 244 letters, spanning Wittgenstein's life from when he started studying philosophy at the University of Cambridge until his death in 1951, also contains comments by Leilich.
