“ There is no reason for a sound faith to be irrational. A useful faith should not be blind, but should be well aware of its grounds. A sound faith should be able to use scientific investigation to strengthen itself. it should be open to the spirit not to lock itself up in the letter. A nourishing, useful, healthful faith should be no obstacle to developing a science of death. ”
