Perfection is an illusion, there's always room for upgrades and excess cup-holders. But just because perfection is impossible to reach, it doesnt mean we should try to reach it, after all, we may not achieve perfection, but atleast we get the second best thing. So yes, we should strive for perfection. Dont know about the embryo killing, on the other hand it would be nice to prevent the birth of more white trash and whatnot, but then again we dont have the technology nor the moral rulesets to define who gets to live and who doesnt.
Man ought to reach for perfection (no matter how unreachable it is) for that act is the driving force behind progress, evolution and man's ascend to greatness. Also: morals schmorals...
Why is perfection beyond achievment? Common sense dictates that everything has it's limits. A car can only travel so fast etc. So why should it be impossible for humans to reach their very best? I agree with the belief that "ridding" the planet of such foolish people would be a nice place to start, but to kill people to achieve such an ends must corrupt such an end. How can humanity be perfect if to reach that point we have killed everbody that detracts from our perfection? Such an act shows that we are from perfect.
You're assuming that a fast car is a perfect car. I think most people (bar Jeremy Clarkson) would disagree with you.
I think he meant that the speed of cars have their limits, which can be achieved, just like humans have limits. The perfect human would then be a human who is at said limits.
Why not? Of course, to return to the car analogy, speed isn't the only factor. If all factors in which a car can be rated (of course, this wouldn't work for a car, but for now, let's stick with it) are limited, a car who reaches every single one of those limits would be the perfect car.
Because there are no limits of how fast a car can drive and there are no limits of what a human can become.(though we can of course question if the person is still human at that point, but that's not really your argument here)
I don't see any possible limit to sight or strength.(and even then you havn't accounted for something like processing capacity and other brain stuff, which would also be a part of the perfect human) Where/when exactly would that be?
I wouldn't know where the limit is, but I can't possibly see how someone could have the strength lift, say, a planet. Sight-wise, you're not only limited physically, but also by the light input. Of course, those are just two examples.
You can't actually "lift" a planet per se in the same way that you could lift a car for obvious reasons.(the car rests on the planet and is affected by it's gravity and atmosphere, while a planet isn't impacted the same way) You could, however, theoretically "push" a planet out of orbit if you had enough mass and velocity, though the planet would probably be smashed to pieces by such a force. A human would never of course be used as such a "projectile" for practical purposes, but I don't see why man(theoretically) couldn't achieve the strength to push a planet out of orbit even though it would be ridiculously impractical and without a lot of benefits. What do you mean by light input? Enhancing vision would of course require a larger brain to process the information received by improved sight sufficiently.
Theoretically, this might all be possible. I still have doubts about the practice, though. Wait...actually, scrap that, I'm not sure if what I was thinking is correct.
