Ethics and the present moment

I'd like to talk a little more about ethics today. First off what is Ethics? My first philosophy prof defined it by saying that it was a way to figure out how to act in the best possible way in whatever circumstances are present. So where metaphysics is the philosophy of reality, and epistemology is the philosophy of knowledge, ethics is the philosophy of the now. Instantly when I put it in these terms new doors of consideration open up for me. I begin to remember what many great men have said about the present moment. Like Wittgenstein:"he who lives in the present moment lives in eternity", or Einstein who said something along the lines of "the only real time is the present moment. Everything else is a mental construct."(paraphrased) With these considerations I come to see ethics in an entirely new light. I begin to see it as the sole philosophy capable of transcending the borders of the mind and enable us to see past the meagre capacities we're used to so we can live perfect lives. Ethics really is a practical philosophy. Every moment you live can be dictated by an ethical theory if you let it. All that I'd ask is that the theory stays in the present, focused on you and nobody else. It must necessarily be a subjective theory, a set of rules that the individual sets up for himself in his own best interest. As soon as you start considering things like the categorical imperative with all its consideration on universal law, or utilitarianism with its consideration of spreading happiness, you start getting muddled up with things that are part of that mental construct. You divest yourself of the present moment and begin considering things from someone else's perspective. This leads to all sorts of assumptions about things that really aren't any of your business and that you could never hope to have a clue about how to deal with. Staying present becomes worthy of approbation in itself.
Later I'll relate this to an established ethical theory and go into more of the practical aspects of the present moment (esp. how it relates to the ego).
