"Pantheist"

From Wikipedia.com:

However, some pantheists hold that the pantheist viewpoint is the most ethical viewpoint, pointing out that any harm done to another is doing harm to oneself because what harms one harms all. What is good and evil isn't the mandate of something outside of us, but as a result of the way we are all interconnected. Instead of good choices being based on fear of divine punishment, it comes from a mutual respect from all things.

Baruch Spinoza (1632-1677) established the formal philosophy of Pantheism over 300 years ago. In his “Ethics” he wrote:

Whatsoever is, is in God, and without God nothing can be, or be conceived. God is the indwelling, and not the transient cause of all things.

—Baruch Spinoza

Albert Einstein appeared to agree with Spinoza when he said:

I believe in Spinoza's God who reveals Himself in the orderly harmony of what exists, not in a God who concerns himself with fates and actions of human beings

—Albert Einstein

God does not die on that day when we cease to believe in a personal deity, but we die when our lives cease to be illuminated by the steady radiance, renewed daily, of a wonder, the source of which is beyond all reasoning. When the sense of the earth unites with the sense of one's body, one becomes earth of the earth, a plant among plants, an animal born from the soil and fertilizing it. In this union, the body is confirmed in its pantheism

—Dag Hammarskold, Secretary General of the U.N. (1953-1961)
