Skepticism literally means a thoughtful inquiry, the looking at a problem in a disinterested spirit, the surveying of a question from many sides. In this sense it is the very essence of philosophy and science.

If the spiritual values of human existence at its highest term of development and achievement do not endure, amidst all the changes and chances of this mortal universe, there seems to be no stable or coherent meaning in existence. Then the universe is irrational--indeed it is no universe at all.

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.

This is the very heart of true morality--not to struggle, not to fight with any weapons, for one's self alone--but to struggle and to fight for the common interest, to wield the power of brain and good right arm if need be for one's family, for the ordered community of life, for the state, for moral principles, humanity, and the common good.

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