This is a comparatively short chapter: I have not given a very great number of passages for criticism, nor very many questions of concept to be answered. For this there are several reasons. First, inasmuch as the book is used in sixth forms and for the benefit of any students who face examinations, their teachers will be primarily concerned with the particular kind of general paper relevant to the needs of their particular students: and of course, apart from the fact that they all include questions of concept, these papers vary very widely. Teachers will naturally want to make use of past papers printed by universities and colleges, and direct the attention of their pupils to the sort of passages and questions which these include. Secondly, those who read this book without any examination paper in view are likely to be interested in one field of thought rather than others: thus some will be more concerned with religion, others with politics, others again with morals, and so on. These specific interests are important, because they give an extra incentive for the analysis of concepts: someone seriously concerned with religion is likely to do more justice to the concepts involved in a passage dealing with religion than to those involved in passages dealing with other matters.
