Political dissension is doubtless a less evil than the lethargy of despotism: but still it is a great evil, and it would be as worthy the efforts of the patriot as of the philosopher, to exclude its influence if possible, from social life. The good are rare enough at best. There is no reason to subdivide them by artificial lines.
