Peter Daniel Francuch, Ph.D.: Fundamentals of Human Spirituality, Santa Barbara/California 1982
"This book is meant for the wide variety of readers who are interested in spiritual issues. The language is accommodated to that purpose. However, some issues have a deep, philosophical content and require elaboration and use of appropriate language. For that reason, it is not always possible to maintain the desirable simplicity and clarity congruent with all levels of human understanding. This is especially true with regard to the first chapter, part one, of this book.
Whatever transpires in this book is not meant for arguments, agreements or disagreements. It is not meant as a command, an order, a demand, a contradiction or a belief system which must be
accepted. The purpose is to give people an opportunity to reflect, contemplate, meditate and seriously consider what is said for their own spiritual benefit, growth and progress. If it fulfils this purpose, no more is expected."
