I think it will be pretty obvious that writing a review of this book is a little hard, if for no other reason than the fact it is a science heavy book in which some of the science is quite out of date.
This is a book written in the 1990’s, so this is something that can’t be avoided. I usually don’t like to read this type of book when so much time has passed between its publishing and the time I am reading it; however I still found it worthwhile and interesting to read. I have given it 3 stars, because it is a bit dated. I tried to kind of balance my review; the first half is mostly a going over the science related to the quest to extend the human lifespan, and this is the half that brings the rating for this book down. It is obvious that the science is behind what we now know, so I have to say it is hard to find fault in faulty research because the research Dr. Bova quotes at the time he wrote this book was the most up to date knowledge we had on these subjects. Keeping this in mind I didn’t down grade my review for this reason; rather I found the way Bova returned to subjects throughout the book to restate points he already had made, to be off putting. At times it seemed he thought the reader might be too uninformed to follow his train of thought, or the scientific information being put on the page.
The second half of the book shows Dr. Bova’s strong suit, the speculation about the reaction to and consequences of, human immortality. This may be easily chalked up to the many years he has spent honing his skills as a science fiction writer, but whatever the reason, it is in this area of the book where he makes his most impassioned, lucent, and powerfully persuasive argument against just thinking about human life expansion as either something silly and impossible, or completely undesirable. He points out the swift and accelerating advance of bio-science over the previous 50 years (in this case reading this book many years in the future actually makes his points even more persuasive) and presents the many examples of people constantly telling us something can never happen only to find it being done within the space of a few years.
He takes apart many of the political and – especially – religious objections to human life being extending. That is why this book is 3 stars; because Dr. Bova, above all else, makes his argument for the inevitable immortality of man in a completely convincing way. His most interesting point, for me anyway, was the way he examined human society in terms of backward looking institutions, and forward looking institutions. He explains that that political, social, and religious institutions are designed to keep the status quo, and maintain a stable society in which laws and ethics are the basis of that stable society, and then points out that science is different. Science is a revolutionary pursuit, which is always looking forward, while those other institutions are backward looking. Thus we find that, through the maintenance of the status quo, those other organizations allow us to have the ethics and morals we know, but that without science as a balancing influence for revolution on our society, we would stagnate and fall backwards eventually.
Read this book for the second half, and do some additional reading to see how far along we are on the road to immortality. See you on your 300th birthday!
