Easily achievable, certainly not. Well defined, possibly.

Morals and ethics. Things which were heavily taught in earlier times, and which now have been replaced by STEM.

Someone is going to squwak that morals and ethics have been debated for millenium, thus certainly NOT well defined.

response: nice STEM thinking, which assumes a mathematical definition of "defined".

VS a morals and ethics definition, which says "here are the points of variance which go into moral decision making." Where a "definition" is not an answer, it is a framing of the debate.

Because moral decisions are always tradeoffs along different dimensions. And moral reasoning is about making judgement calls under uncertainty.
