There seems to be a growing consensus in psychology and philosophy that there are two classes of moral process: 1) rational, effortful and explicit, and 2) emotional, quick and intuitive. The controversy remains in how they interact. Certainly, the neural underpinnings of morality are not yet well understood.
Good point!
We create our own classifications in order to facilitate some process of understanding. The separate disciplines in science, such as Biology, Physics and Chemistry, do not exist as separate entities in external reality, but are restrictions and labels we've created in order to help us focus on a particular, narrow part of the spectrum of 'all knowledge'.
In reality there are no boundaries, just as there's no boundary between the color green and the color blue. This is why I keep bringing up the issue of duality in such discussions. There's a tendency to categorise things in common language so that they are 'either this' or 'that'.
As regards morality, perhaps the most fundamental of all moral principles is the Golden Rule, 'Do unto others as you would have them do unto you'. This moral principle, in its broad meaning, includes other more recently expressed moral principles such as, 'Love thine enemy', and 'Love thy neighbour as thyself'.
However, without emotion and empathy, the Golden rule is deeply flawed. Empathy is required in order to understand the rule.
To give you a specific example, imagine a male who sees a female stranger in the woods, or wherever. They both look at each other and say hello. The woman thinks, 'I hope he moves on. I don't like him'. The man thinks, 'I hope she rushes towards me, and embraces me, and rubs my body, and so on'.
However, the woman doesn't do that, as one might understand. The man, however, thinks of the Golden Rule, 'Do unto others as you would have them do unto you'. Lacking empathy, he rationalizes along the lines, 'I would like her to rush towards me and smother me with kisses, so I'll do unto her what I would have her do unto me'.
He rushes towards her, and embraces her and smothers her with kisses, and she screams, 'Get off me you bastard. Help! Help! I'm being raped'.
I can't believe I'm writing this sort of thing on a Photography forum.
However, I
have used some photography-related analogies, so perhaps it's justified. The part of the electromagnet spectrum known as 'visible light' ranges from 400 to 700 nanometres. (A nanometre is one thousand-millionth of a metre.)
Between the colors Red and Violet there are therefore 298 different colors. How many have we named? This is not the same question as how many shades of different colors can we distinguish, which would presumably be much greater than 298 because of different degrees of luminosity, and the mixing of different colors from different parts of the spectrum.
I use this analogy to highlight the imprecision of dualistic, 'either/or' concepts.
