Human progress is not an uninterrupted march forward. It is a slow and devious movement with haltings and twistings. The pathway of man ascends and descends, wanders off into mazes. At times the trail seems to lose itself in the wilderness of human passion and folly. But inch by inch it goes forward with halting steps.

No generation can do another generation's work for it.

Philosophy, like science, consists of theories or insights arrived at as a result of systemic reflection or reasoning in regard to the data of experience. It involves, therefore, the analysis of experience and the synthesis of the results of analysis into a comprehensive or unitary conception. Philosophy seeks a totality and harmony of reasoned insight into the nature and meaning of all the principal aspects of reality.

God is a wider consciousness than we are, a pure intelligence, spiritual life and actuality. He is neither one nor many, neither man nor spirit. Such predicates belong only to finite beings.
