Consider impact before you consider benefit.

It is quite likely that it is possible, yes. But what we've said all along -- speaking for both the (Roslin) Institute and the PPL staff - is that we would find it ethically unacceptable to think of doing that. We can't think of a reason to do it. If there was a reason to copy a human being, we would do it, but there isn't.

When someone copies you, they are copying a moment in time. They don’t know the thinking that went into getting you to that moment in time, and they won’t know the thinking that’ll help you have a million more moments in time. They’re stuck with what you left behind.

It's always worth while before you do anything to consider whether it's going to hurt another person more than is absolutely necessary.

First, you have to figure out who to copy. Second, you have to figure out what to copy.

If I used to ask myself, over a coffin, "what good did it do the occupant to be born?" I now put the same question about anyone alive.

When making decisions most people ask, ‘Will it help me or my family now or the next shareholders’ meeting or my next election campaign?’ The hallmark of wisdom is asking, ‘What effects will the decision I make today have on future generations? On the health of the planet?

I used to ask myself, over a coffin: “What good did it do the occupant to be born?,” I now put the same question about anyone alive.

Miles had heard weird tales of strange relationships between people and their clones. But then, anyone who deliberately went out and had a clone made must be kinky to start with. Far more interesting to have a child, preferably with a woman who was smarter, faster, and better-looking than oneself; then there was at least a chance for a bit of evolution in the clan.

Copying others is a good way to start. Copying yourself is a disappointing way to end.

To copy others is necessary, but to copy oneself is pathetic.

It is very good to copy what one sees; it is much better to draw what you can't see any more but is in your memory. It is a transformation in which imagination and memory work together. You only reproduce what struck you, that is to say the necessary.

I don't know much about morality and that, but there is this: It's always worth while before you do anything to consider whether it's going to hurt another person more than is absolutely necessary.

The nature part of human nature is to make copies of ourselves — as it is with any other .
