Maybe it is wrong to decide what is right. I don’t know. We do a lot of it, though; and maybe it would be helpful to get some of our terms straight, so while we are doing it, we at least know what we are about.

Here’s an informal primer on such:

MORALS. Something is moral or immoral because we have decided what is appropriate behavior in our own and others’ lives.
ETHICS. Something is ethical or unethical because we have decided what is appropriate interaction between ourselves and others.
LEGALITY. Something is legal or illegal because we have decided what rules we and others will abide by.
VALUES. Something has value to us because we have decided on the high quality of something, some action, some way of doing.
PRINCIPLES. Something  is principled or unprincipled because we have decided to believe something guides our behaviors, relationships and actions.
OPINION. Something is an opinion when it is a judgment based on grounds that are NOT sufficient to produce complete certainty.
GOSSIP. Something is gossip when we confuse any of the above.
