belief and doubt are living attitudes, and involve conduct on our part. Our only way, for example, of doubting, or refusing to believe, that a certain thing is, is continuing to act as if it were not. If, for instance, I refuse to believe that the room is getting cold, I leave the windows open and light no fire just as if it still were warm. If I doubt that you are worthy of my confidence, I keep you uninformed of all my secrets just as if you were unworthy of the same. If I doubt the need of insuring my house, I leave it uninsured as much as if I believed there were no need.
