The Beginning and the End: The Meaning of Life in a Cosmological Perspective
(continued from here)
I would now like to conclude my discussion of this important work.Chapters 5 and 6 continue to investigate the question of the origin of the cosmos. Perhaps the most important result for the average reader is that the argument for a fine-tuned universe is inconclusive. The discussion in chapters 4-6 leads to the question of the future of the cosmos in Chapters 7 and 8; the question of whether we are alone in the cosmos in Chapter 9; and Chapter 10 the possibility of a cosmological ethics.. There are simply so many profound and novel ideas in these chapters that I’ll leave them to the readers of the book to explore.
The crescendo of the work appears in the last section’s discussion of immortality, where Vidal distinguishes five kinds of immortality:
1) Spiritual – The belief in a supernatural realm where a non-physical soul “goes” after death. This belief is widespread and appealing, but anathema to the rationalistic mind.
2) Individual – The belief that we can be biologically or digitally immortal. Vidal suggests that motivation for individual immortality arises primarily because we are cultural creatures. Our genes survive to a large extent but “most of the information we gather during our lifetime is cultural and gets lost at the time of death. And this is pure waste.” (Vidal, 298) The way out of this problem is biological or digital immortality or some combination of the two. Critics question whether cybernetic immortality is possible without embodiment, whether it’s worth it to live in a simulation, whether its cost will be prohibitive, whether death is good because it motivates us, etc. But Vidal suggests that immortality would force us to worry about things like climate change and the death of our sun and universe, since we will live into the far future. Still we don’t need to be immortal to have transpersonal concerns–we can care about others who will live on after we have died. And the same with our projects, concerns and goals. If they take many generations to achieve, then our deaths do not undermine them. Such considerations lead us to consider transpersonal immortality in three different varieties.
3) Creative – The belief that immortality can be achieved by leaving a cultural legacy. The main problem here is that even the achievements of an Aristotle, Shakespeare or Darwin may be forgotten in thousands or millions of years.
4) Evolutionary – The belief that immortality can be achieved by leaving a biological legacy. For example we are almost immortal at the level of the genes and are potentially immortal as part of a global brain. But even this is not enough if there are cosmological constraints on the immortality of the universe.
5) Cosmological – The belief that true immortality can only be achieved by a connection between ourselves and the immortality of the cosmos. But can the universe continue indefinitely? Perhaps universes could reproduce other universes ad infinitum, or our descendants will become smart enough to determine the fate of the cosmos. Vidal believes that we should be concerned with the issue of cosmological immortality, we can see the immortality of the cosmos as our ultimate goal.
Let me conclude by stating my belief that only with cosmic immortality can complete meaning in life be found. And I agree with Vidal that this is our ultimate goal–the creation and continuation of a good, meaningful, immortal cosmos.
Finally let me reiterate what I said about this work previously. It is a carefully and conscientiously crafted work of immense scope and daring imagination, one of the most important and timely books of the last few decades. Vidal is aware of the speculative nature of his work, but he reminds us that speculation plays a large part in the scientific and philosophical enterprises. He knows his speculations could turn out to be wrong, but given the choice between careful speculation or silence, Vidal chooses the former. And we are glad he did. For his assiduous scholarship reveals the possibility that a scientific cosmology can provide a narrative which gives life meaning. A narrative so desperately needed as the old mythological ones become increasingly passé. And we are privileged to journey along with his well-ordered and visionary mind as it contemplates perhaps the most important question of our time–how do we find meaning in the cosmos revealed by modern science.
I have thoroughly enjoyed reading the book.
