Ecclesiastes said that "all is vanity," Most modern preachers say the same, or show it By their examples of true Christianity: In short, all know, or very short may know it.
The majority of mankind is lazyminded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith.
The most vulnerable and yet most unconquerable of things is human vanity; nay, through being wounded its strength increases and can grow to giant proportions.
