Hi! I want to answer your question satisfactorily, but you may have to help me understand precisely what you mean. It is rather easy to see that it's preferable to live in an environment of holistic peace and prosperity, rather than trying to create such a pocket of existence amidst a dangerous, zero-sum world.

This leads us to ask how that can be achieved. The behaviors that would produce this environment are equally obvious - people need to cooperate for mutual uplift, rather than live in selfish competition. Of course, for this to happen, each individual must exhibit this behavior; and I, being one of those individuals, must thus exhibit it myself. For me, that recognition provides adequate motivation for moral behavior.

I can mention teachers who have helped me come to this realization, but it seems your question is not served by listing names (the great philosophers, etc.). I do not mention Buddhism because I do not know much about it. Of course, I've come across it in my investigations, but I would be hard-pressed to describe the belief system thoroughly.

My personal philosophy is born of innumerable disparate areas of study, and the personal contemplation they've inspired. It is the work of many years, and I could not describe it as a step-by-step process that another could follow. I'm not sure this would serve as well as someone following their own inspiration and interest anyway. Though, this does require that they seek Truth in earnest, and not merely seek to justify their preconceived conclusions.

Please tell me if I have approached a sufficient answer to your question. If not, perhaps this reply can at least move the discussion forward toward the desired end.
