Alfred North Whitehead
Wisdom combines truths of science, philosophy, and spiritual experience. Excellent thinking flourishes on the basis of intuition. On that basis, reason draws inferences. Then wisdom integrates reason’s diverse array of such lines of reasoning into an ever more comprehensive synthesis. (In practice, each phase of this model depends on the other phases.)
Wisdom emerges in Alfred North Whitehead who, after a career in science at Cambridge, took up a second career in philosophy at Harvard. He saw the need for a philosophy of living.
Philosophy is not a mere collection of noble sentiments. A deluge of such sentiments does more harm than good. Philosophy is at once general and concrete, critical and appreciative of direct intuition. It is not—or, at least, should not be—a ferocious debate between irritable professors. It is a survey of possibilities and their comparison with actualities. In philosophy, the fact, the theory, the alternatives, and the ideal, are weighted together. Its gifts are insight and foresight, and a sense of the worth of life, in short, that sense of importance which nerves all civilized effort. Mankind can flourish in the lower stages of life with merely barbaric flashes of thought. But when civilization culminates, the absence of a coordinating philosophy of life, spread throughout the community, spells decadence, boredom, and the slackening of effort.
At the high point of his philosophy, Whitehead creatively combined his concept of an eternal God with his concept of evolution. In this way he came very close to the main thesis of this philosophy of living. Truth, beauty, and goodness are qualities of the eternal nature of God; and these values evolve in time as we actualize them. To live them is thus the sense in which it is humanly possible to live the divine life.
These ideas suggest that our greatest insights into truth, beauty, and goodness lead us to regard these values as qualities of God; but in our own lives, these values are partial and incomplete, more potential than actual. The process of actualizing them is a long and gradual evolutionary process. Through our struggles, God leads us to partake of these divine values and become increasingly like him.
Think of the times when you are living at your best. Could you describe these times as living the truth? Walking in beauty? Participating in divine goodness? All of these blended together? Please say more. Feel free to respond to just part of this huge question–or to modify the question as you choose.
