Context

“but it must render an Englishman peculiarly ill-qualified to pass a judgment on the original tendencies of human nature from his own experience. The errors to which observers elsewhere are liable on the subject, are of a different character. An Englishman is ignorant respecting human nature, a Frenchman is prejudiced. An Englishman's errors are negative, a Frenchman's [Pg 125] positive. An Englishman fancies that things do not exist, because he never sees them; a Frenchman thinks they must always and necessarily exist, because he does see them.” source
