The two considerations just mentioned must be subordinated to the grand one,--the only general one,--of the relative amount of human happiness. Every element of social life derives its importance from this great consideration. The external conveniences of men, their internal emotions and affections, their social arrangements, graduate in importance precisely in proportion as they affect the general happiness of the section of the race among whom they exist. Here then is the wise traveller's aim,--to be kept in view to the exclusion of prejudice, both philosophical and national. He must not allow himself to be perplexed or disgusted by seeing the great ends of human association pursued by means which he could never have devised, and to the practice of which he could not reconcile himself. He is not to conclude unfavourably about the diet of the multitude because he sees them swallowing blubber, or scooping out water-melons, instead of regaling themselves with beef and beer. He is not to suppose their social meetings a failure because they eat with their fingers instead of with silver forks, or touch foreheads instead of making a bow. He is not to conclude against domestic morals, on account of a diversity of methods of entering upon marriage. He might as well judge of the minute transactions of manners all over the world by what he sees in his native village. There, to leave the door open or to shut it bears no relation to morals, and but little to manners; whereas, to shut the door is as cruel an act in a Hindoo hut as to leave it open in a Greenland cabin. In short, he is to prepare himself to bring whatever he may observe to the test of some high and broad principle, and not to that of a low comparative practice. To test one people by another, is to argue within a very small segment of a circle; and the observer can only pass backwards and forwards at an equal distance from the point of truth. To test the morals and manners of a nation by a reference to the essentials of human happiness, is to strike at once to the centre, and to see things as they are. SECTION II.
