First of all, I do endeavor to prolong my life by treating my health, eating right, not smoking, taking vitamines and minerals, etc.
But it is important not to hurt the quality of life in the quest to increase the quantity, or length, of it.
Also - as to your philosophical point: I have to point out that life alone is not the source of values. That life IS terminable is that source.
If you were a God, who needed nothing to remain alive, nothing to improve your life - and nothing could endanger this status - you will be completely ammoral. You will not need any principles to guide your actions. What for? Your situation could not get better or worse.
Food will just become a mindless indulgence, when nutrition is gone. Work will be just a way to “kill time”, when you have no time limit, no financial goals. Everything will lose it’s meaning and significance.
Fortunately - this is impossible. Man can NEVER become in principle indestructible. You will always have to maintain your life, and your goal oriented approach.
I completely disagree with this and consider this an ancient worldview. No disrespect intended as I value all your other contributions. But the view you just described was the way the ancient Greeks viewed their gods. The gods were “undying” and this was the main distinguishing characteristic b/w gods and men. B/c gods could not die they could not know courage or fear. The Greeks considered their mortality as the essence of what made them human. Now this was fine for 2500 years ago but in light of modern philosophy and science I consider it outdated.
I do not think that immortality would destroy mankind’s purpose and his meaning. Think about what you are saying. Its almost like an environmentalist argument. Imagine tommorrow that a sceintist discovers a way to achieve immortality. You would make it seem that this man was a destroyer of man’s soul. In fact that is almost always the way science fiction depicts immortality; as a destructive goal that robs mankind of his humanity. And further, that is the way that the moderns view bio engineering. Read Alex Epstein’s article in the TIA for the current views on bio-ethics. He was not talking about immortality per se. But what else could be the possible end of bio-engineering?
As for indestructability. I don’t think immortality means indestructability. People could still die or be hurt. Immortality could take many forms; transferring intelligence and memmory into a new cloned body for example. Were not talking about Ayn Rand’s indestructable robot with no values here. Were just imagining a time when men stop the aging process and find a way to perpetuate youthful, strong bodies and minds.
I don’t know about you, but to me that is one of the greatest accomplishments men could achieve. I don’t relish dying and I don’t consider it some honor for a life well lived. Dying will probably be looked upon by some future society as the inevitable consequence of a culture that worshiped death. I would argue that in a fully Objectivist culture people would not die. It just makes no damn sense. Remember Ayn Rand’s passage from Atlas where she says the circle is the shape of nature whereas the straight line is the mark of man. A rational culture would spit at the “circle of life.”
Forgive me for taking a position which is controversial even for Objectivists but I’m passionate in my hatred for death.
