You already know where I get mine from.
No, I don't. I find what you believe to be very unclear. It would really helped me if you would define what you mean by "morality".
No, I think i'd rather hear YOUR definition of morality, and where YOU get it from.
An action or choice is moral (or right) when it somehow promotes happiness, well being or health or if it minimizes unnecessary harm or suffering or it does both. It is immoral (wrong) if it diminishes happiness, well being, or health or it somehow cause unnecessary harm or suffering or, again, it does both.
I get this from observations on the use of morality by people around me, and from its usage in literature and other forms of media. Generally if I am talking about things that are moral following these guidelines people tend to already understand that these are moral without me explaining my definition to them, which is to some degree an indicator that it is on the right track.
Also, notice how nothing about this is subject or relativistic. The fact that murder causes harm, or saving a life minimizes it, is not a personal opinion that is only true for me. Harm, pain, suffering, health, well being; these are real things. They are not contingent on my mind. I don't have to agree that someone is dying for them to actually be dying. People live and they die. They experience pain and suffering and they experience joy and health. Even with our limited technology, this is still objectively measurable. For example, you can use a electroencephalography machine and which parts of the brain are being affected, and to what degree, when the person is subjected to certain experiences. Different parts of the brain will light up when someone experiences sadness than when someone experiences joy. When we hurt or help a person, it causes real quantifiable things to happen in that person's brain. Yes, this may be a subjective experience for them but it is still objectively happening. From this we can determine, objectively, whether things are moral or immoral.
Plus, I am pretty sure we don't need state of the art technology to be able to recognize that things like rape and murder cause unnecessary harm and suffering.
Treat others how you'd like to be treated yourself.
This is actually a very bad version of the golden rule. I don't think it is very useful. In fact, I think it can be quite harmful.
