Have faith in man, whether he appears to you to be a very learned one or a most ignorant one. Have faith in man, whether he appears to be an angel or the very devil himself. Have faith in man first, and then having faith in him, believe that if there are defects in him, if he makes mistakes, if he embraces the crudest and the vilest doctrines, believe that it is not from his real nature that they come, but from the want of higher ideals.
