“ Another defect of this method is that the author often fails to indicate with sufficient clearness the results of his discussion. For example, the section entitled "What is a judgment?" would hardly enable the beginner to obtain a clear conception of the author's view.
In the present state of logical science the writer of a text-book has no easy task before him, but for once the savor of the middle ages remains only in a few forms. Logic is defined as "the study (Lehre) of correct thinking." ”

“ It is perhaps a defect, that the book hardly succeeds in vindicating a clear and distinct sphere for logic. The main purpose of the writer is to make students think, and, if I mistake not, his clear-cut definitions and wide variety of example will prove a stimulus for more advanced thinkers than those for whom it was intended. ”
