xviii PREFACE 



tion and sound criticism, are unrolled by Dr Lluria 

 in his beautiful work, written, I may remark, with 

 clearness, brightness, and suggestion, and with a 

 mastery of thought and calmness of judgment 

 which might be the envy of many well known in 

 the world of philosophy and social science.
