Every man should be responsible to others, nor should anyone be allowed to do just as he pleases; for where absolute freedom is allowed there is nothing to restrain the evil which is inherent in every man. But the principle of responsibility secures that which is the greatest good in states; the right persons rule and are prevented from doing wrong, and the people have their due. It is evident that this is the best kind of democracy, and why? because the people are drawn from a certain class.
What has soul in it differs from what has not, in that the former displays life. Now this word has more than one sense, and provided any one alone of these is found in a thing we say that thing is living.
