Campbell is a more lucid writer other authors in historical linguistics (one for example, Theodora Bynon's Historical Linguistics) are, since he describes 'seven steps' of the comparative method and 'four steps' of the method of internal reconstruction. In these steps, technically reductio ad absurdum and ad hominem is employed in 'directionality' to argue for direction of change from a phoneme to another (pp.116, 203-204). Also is employed ex concesso in 'the majority-wins principles' (p. 117) and 'factoring in features held in common' (p. 118) to postulate a phoneme for a proto-language sound. In a word, as a graduate student in linguistics I can unquestionably recommend that a learner of historical linguistics study this book.
