If mind is common to us all, then we have reason also in common – that which makes us rational beings. If so, then common too is the reason which dictates what we should or should not do. If so, then law too is common to us all. If so, then we are citizens. If so, we share in a constitution. If so, the universe is a kind of community. In what else could one say that the whole human race shares a common constitution?
