This is a somewhat technical study of the nature and function of symbols in communication, culture, art, religion, and--to some extent-- science. The essential symbolic nature of all communication is taken as a starting point, and the relevance of this principle to the artistic, religious, and intellectual enterprises of the person and of human society, are set forth. There is considerable reference to the works of various philosophers and other writers, with a special dependence upon the work of Ernest Cassirer. The plethora of quotation and allusion, coupled with a rather flat style and a resort to abstract generality make for somewhat uninspired reading. One looks in vain for more of the author's own insights and a more incisive and illuminating presentation. This is a volume in the Westminster Studies in Christian Communication Series.
