 This imporant aspect of “the magical power of words” has again been examined carefully in terms of language study as it relates to the uses of logic in theology by Rosier-Catach (2004). Graziella Federici Vescovini (2011) has now presented a magisterial study of the close connection of philosophy and natural magic in the Middle Ages, accentuating the notion of “the magical power of words” in relation to Bacon and other medieval philosophers. This magical power of words, derived from Alkindi, has a connection with Bacon’s theory of communication in part five of the Moralis philosophia.
