Communication is the key to progress. We must learn to communicate with other species or perish. We are not alone in this universe and we should be able to express our ideas and aspirations to other species because we may not meet on equal terms.
Following his previous book, A Magic Life and Time Yoga, the author writes about communication and the philosophy of past, present, and future efforts to communicate. This is a non-technical book for the average reader who likes to think things out themselves.
