@liminal asks: How do you decide what is right or wrong?
I use a combination of what I’ve been taught (from my parents, teachers, and authorities – from both a secular and sacred point of view), things I’ve learned on my own (study of various books, including the Bible), personal experience, the law of the land, on-going feedback from others, guidance from my Higher Power, and from my own internal compass.
@liminal asks: How do you decide if your source of right or wrong is right or wrong?
If whatever element of the above-mentioned combination doesn’t make logical sense, doesn’t feel good, doesn’t fit the situation, and/or harms myself or others, then I label the element “wrong.”
As far as the specific source is concerned, whether it is right or wrong, if the majority of its elements reveal themselves to be “wrong” (by using the above-mentioned filter, then I would have to say that the source is wrong.
@liminal asks: How do you decide whether to use your sense of right or wrong to decide another’s life or behavior is right or wrong?
There are some moral absolutes I hold true for all people at all times, regardless of their belief system. I won’t go into specifics, but they are along the lines of sanctity of life and maintaining a safe environment. I think it is necessary for the well-being of myself and others to use these standards to judge others. For example: I think it would be wrong for someone to murder another person.
There are some convictions I have based on my belief system. It wouldn’t be fair or appropriate to judge another person based upon my beliefs if the person is of another belief system. However, if the person is of the same belief system, then I think it is okay to evaulate behavior in order to give corrective feedback (if it fits the relationship and is not self-righteous judgement). Example: I think it is appropriate for the sensei of a dojo to judge the actions of a student.
Regardless of the basic moral absolute or the collection of right behaviors found in my belief system, I believe there is room to evaluate situations on a case-by-case basis. There could be extenuating circumstances, etc, that require the practice of not applying or changing the rules. (Some would call this practicing mercy.)
