--Alfred North Whitehead, mathematician and philosopher (1861-1947)

(69:9.18) The present social order is not necessarily right—not divine or sacred—but mankind will do well to move slowly in making changes. That which you have is vastly better than any system known to your ancestors. Make certain that when you change the social order you change for the better. Do not be persuaded to experiment with the discarded formulas of your forefathers. Go forward, not backward! Let evolution proceed! Do not take a backward step.

(114:6.7) The religious guardians. These are the "angels of the churches," the earnest contenders for that which is and has been. They endeavor to maintain the ideals of that which has survived for the sake of the safe transit of moral values from one epoch to another. They are the checkmates of the angels of progress, all the while seeking to translate from one generation to another the imperishable values of the old and passing forms into the new and therefore less stabilized patterns of thought and conduct. These angels do contend for spiritual forms, but they are not the source of ultrasectarianism and meaningless controversial divisions of professed religionists. The corps now functioning on Urantia is the fifth thus to serve.

    Alfred North Whitehead was an English mathematician and philosopher. He is best known as the defining figure of the philosophical school known as process philosophy, which today has found application to a wide variety of disciplines, including ecology, theology, education, physics, biology, economics, and psychology, among other areas.
    In his early career Whitehead wrote primarily on mathematics, logic, and physics. His most notable work in these fields is the three-volume Principia Mathematica (1910–1913), which he wrote with former student Bertrand Russell. Principia Mathematica is considered one of the twentieth century's most important works in mathematical logic, and placed 23rd in a list of the top 100 English-language nonfiction books of the twentieth century by Modern Library.
    Beginning in the late 1910s and early 1920s, Whitehead gradually turned his attention from mathematics to philosophy of science, and finally to metaphysics. He developed a comprehensive metaphysical system which radically departed from most of Western philosophy. Whitehead argued that reality consists of processes rather than material objects, and that processes are best defined by their relations with other processes, thus rejecting the theory that reality is fundamentally constructed by bits of matter that exist independently of one another. Today Whitehead's philosophical works – particularly Process and Reality – are regarded as the foundational texts of process philosophy.
    Whitehead's process philosophy argues that "there is urgency in coming to see the world as a web of interrelated processes of which we are integral parts, so that all of our choices and actions have consequences for the world around us." For this reason, one of the most promising applications of Whitehead's thought in recent years has been in the area of ecological civilization and environmental ethics pioneered by John B. Cobb.
