A quote
Life without ideals is erratic: as soon as an ideal is to be set up, doctrines begin to be necessary. I am sure you will admit that there is nothing more shameful than uncertain and wavering conduct, than the habit of timorous retreat. This will be our experience in all cases unless we remove that which checks the spirit and clogs it, and keeps it from making an attempt and trying with all its might.
