We must come down from our heights, and leave our straight 
paths, for the byways and low places of life, if we would 
learn truths by strong contrasts; and in hovels, in forecastles, 
and among our own outcasts in foreign lands, see what has been 
wrought upon our fellow-creatures by accident, hardship, or vice. 
- Richard Henry Dana, Jr. 1836
