The Distinction Between Science and Morality

Popper, it's a bit hard to interpret on issues of objective morality, because he doesn't really discuss that point. I like to use the argument that there's a difference between the possibility of progress in morality and in science. And all knowledge is conjectural. The fact that you can't deduce it from anything is irrelevant in all fields. Knowledge can never be deduced. But we're not after deducing knowledge and what we're after is solving problems. There have to be moral problems as soon as you have a creative entity that is solving problems - then moral issues arise.
