I am not sure if the following will muddy things or clarify things that in my own mind are hardly set. Hardly set means that I do not have a systematic sense of how a triad exists in the mind. In my own practice it suffices to repeat to myself the key words of my own sense of the order in which things should be done to achieve the result I urge. I assume that we begin with Reality which might be a conscious (thought, considered) thing like my friendship with X and that I would then move to ethics which for me might mean merely considering that word, but which more often means saying to myself the four values I deem to be ontological and efficacious in moving toward action. These are tolerance, helpfulness, democracy and non-idolatry. The actual application of these terms varies with the Reality. In this case I might consider tolerance in terms of the effect on others or on myself of pursuing the relationship. I might consider helpfulness in terms of what is good for all concerned. I might consider democracy as counselling the sanctity of each individual. And non-idolatry as the need to heed finally the one I call Abba but which one could also call Reality or some other name, not excepting one's higher self. This consideration would not take more than a few seconds in practice. The final step would be a decision or resolution relating to the relationship under consideration.
My approach to said relationship would be informed by this process. In the case of this example the act might be a written word which represented my determination of the best resolution of the relationship from my side of it. This is a pretty accurate description of what I mean by thinking in threes, though the realities are so innumerable that the results would be massively varied as well. I hold that we can and should consciously embrace this mode of thinking, recognizing that history is driven by our choice of values and that ethics in itself is these values and that they can and should influence the act or expression that emerges. That act I see as the aesthetic element in all of life. Musement is a good word for how this thinking process takes place. It is focused, discreet and real. But it is also to some extent quite free and open. Though personal it is inevitably social as most action is.
