Belief, as I use the word here, is the insistence that the truth is what one would "lief" or wish it to be. The believer will open his mind to the truth on condition that it fits in with his preconceived ideas and wishes. Faith, on the other hand, is an unreserved opening of the mind to the truth, whatever it may turn out to be. Faith has no preconceptions; it is a plunge into the unknown. Belief clings, but faith lets go.
Of the modes of persuasion furnished by the spoken word there are three kinds. The first kind depends on the personal character ofthe speaker; the second on putting the audience into a certain frame of mind; the third on the proof, provided by the words of the speech itself.
Still, instead of trusting what their own minds tell them, men have as a rule a weakness for trusting others who pretend to supernatural sources of knowledge.
