"I recall the labour with which, over several weeks of intense application, we had studied Wittgenstein's Philosophical Investigations, and the joy that flooded us as the private language argument finally made sense. The same experience was granted with reading Leavis's essay on reality and sincerity in poetry, in which an argument equally subtle and all the more vivid for being focused on concrete examples, suddenly dawned on us, and its implications shot like rays of cheerful sunlight to the furthest reaches of our minds. Those intellectual experiences were not morally neutral. The Leavisite vision of literature, and the Wittgensteinian conception of mind and language, were the vanguards, for me, of a long train of self-examination and critical reflection, in which many dear illusions had to be jettisoned and many values rethought. That is what humane education amounted to: the intellectual revision of the moral landscape".
