In this volume we witness Wittgenstein in the act of composing and experimenting with his new visions in philosophy. The book includes key explanations of the origin and background of these previously unknown manuscripts. It investigates how Wittgenstein’s philosophical thought-processes are revealed in his dictation to, as well as his editing and revision with Francis Skinner, in the latter’s role of amanuensis. The book displays a considerable wealth and variety of Wittgenstein’s fundamental experiments in philosophy across a wide array of subjects that include the mind, pure and applied mathematics, metaphysics, the identities of ordinary and creative language, as well as intractable problems in logic and life. He also periodically engages with the work of Newton, Fermat, Russell and others. The book shows Wittgenstein strongly battling against the limits of understanding and the bewitchment of institutional and linguistic customs. The reader is drawn in by Wittgenstein as he urges us to join him in his struggles to equip us with skills, so that we can embark on devising new pathways beyond confusion. This collection of manuscripts was posted off by Wittgenstein to be considered for publication during World War 2, in October 1941. None of it was published and it remained hidden for over two generations. Upon its rediscovery, Professor Gibson was invited to research, prepare and edit the Archive to appear as this book, encouraged by Trinity College Cambridge and The Mathematical Association. Niamh O’Mahony joined him in co-editing and bringing this book to publication. “I said earlier that the sum of these texts is not greater than the sum of its parts. Still, the parts are the product of a philosophical genius applying himself with the greatest concentration to the topics that drew him most. … Anyone with a serious interest in Wittgenstein who dips into one or another of the texts collected here will be richly rewarded.” (Jason Bridges, Metascience, Vol. 32 (3), 2023) “Gibson and O’Mahony have done a remarkable job and Dictating Philosophy will prove to be of tremendous importance to the field of Wittgenstein scholarship. … the new angles of approach and skillfully crafted examples from these dictations unquestionably provide real food for thought.” (Nuno Venturinha, PHILOSOPHY, The Journal of the Royal Institute of Philosophy, June 16, 2021) “For the archivist it is always a cause for excitement when a new source for our understanding of the work of an important figure becomes available. This was the case when the Mathematical Association first loaned the Skinner manuscripts to Trinity and grew when the content of the material became apparent. The relationship between Wittgenstein and Skinner gives cause to respect their authority as a source for Wittgenstein's thought at a crucial time, when he was developing a number of familiar concepts that we associate with him today. It is the nature of Wittgenstein's work that it appears repeatedly to go over deceptively similar ground, providing us with a variety of examples, each of which illuminates a particular fresh aspect of a philosophical issue. This edition by Arthur Gibson and Niamh O'Mahony of the Witttgenstein/Skinner Archive will newly illuminate many aspects of Wittgenstein's thought, helping us to refine our understanding of it and of the world around us" (JonathanSmith, Archivist, Trinity College Library, Cambridge, CB2 1TQ, UK) “Wittgenstein had many friends with whom he engaged in philosophy, but Skinner was certainly one of the most important ones, an irreplaceable, loved companion, both in Cambridge and other places. Skinner was for example with Wittgenstein in his small house overlooking Eidsvatnet in Skjolden in late September 1937 when Wittgenstein wrote the paragraphs that later became famous as Appendix III of Remarks on the Foundations of Mathematics , Part I. And one year earlier, in August 1936, Wittgenstein brought important notes in Skinner’s hand with him to Skjolden, notes that he had dictated to Skinner and which later would be called the “Brown Book”. Also one of the finest and most accessible pieces of middle Wittgenstein philosophy of language, the “Pink Book” from 1933-34, has its origin in work done with Skinner. The Skinner Archives, published here for the first time, contain many such treasures, and the editors deserve our sincere thanks for making them known to the public and reminding us of the importance Skinner had for Wittgenstein, both in life and philosophy. After all, it was to Francis Skinner that Wittgenstein in 1932 had assigned (“zugeeignet”) his “Philosophische Bemerkungen”, and A. Gibson invites us to contemplate a thought-provoking possibility: What if Francis Skinner had not died early and become heir and editor of Wittgenstein?" (Professor Alois Pichler, Director of the Wittgenstein Archives at the University of Bergen) “The 1946 discovery of the Dead Sea Scrolls provided a completely unexpe
