In general, whenever there is occasion to verify the exactness of a quotation
made in support of a thesis, it is prudent to read the entire chapter whence it
is taken, sometimes even to read the whole work. An individual testimony,
isolated from all its surroundings in an author's work, seems often quite
decisive, yet when we read the work itself our faith in the value of the
argument based on such partial quotation is either very much shaken or else
disappears entirely.
