“The Church has consistently and justly refused to allow that reason might stand in opposition to faith, and yet be placed under subjection to it. The human spirit in its inmost nature is not something so divided up that two contradictory elements might subsist together in it. If discord has arisen between intellectual insight and religion, and is not overcome in knowledge, it leads to despair, which comes in the place of reconciliation. This despair is reconciliation carried out in a one-sided manner. The one side is cast away, the other alone held fast; but a man cannot win true peace in this way. The one alternative is, for the divided spirit to reject the demands of the intellect and try to return to simple religious feeling. To this, however, the spirit can only attain by doing violence to itself, for the independence of consciousness demands satisfaction, and will not be thrust aside by force; and to renounce independent thought, is not within the power of the healthy mind. Religious feeling becomes yearning hypocrisy, and retains the moment of non-satisfaction. The other alternative is a one-sided attitude of indifference toward religion, which is either left unquestioned and let alone, or is ultimately attacked and opposed. That is the course followed by shallow spirits.”
