+63. How laws and institutions differ from mores.+ When folkways have become institutions or laws they have changed their character and are to be distinguished from the mores. The element of sentiment and faith inheres in the mores. Laws and institutions have a rational and practical character, and are more mechanical and utilitarian. The great difference is that institutions and laws have a positive character, while mores are unformulated and undefined. There is a philosophy implicit in the folkways; when it is made explicit it becomes technical philosophy. Objectively regarded, the mores are the customs which actually conduce to welfare under existing life conditions. Acts under the laws and institutions are conscious and voluntary; under the folkways they are always unconscious and involuntary, so that they have the character of natural necessity. Educated reflection and skepticism can disturb this spontaneous relation. The laws, being positive prescriptions, supersede the mores so far as they are adopted. It follows that the mores come into operation where laws and tribunals fail. The mores cover the great field of common life where there are no laws or police regulations. They cover an immense and undefined domain, and they break the way in new domains, not yet controlled at all. The mores, therefore, build up new laws and police regulations in time. +64. Difference between mores and some cognate things.+ Products of intentional investigation or of rational and conscious reflection, projects formally adopted by voluntary associations, rational methods consciously selected, injunctions and prohibitions by authority, and all specific conventional arrangements are not in the mores. They are differentiated by the rational and conscious element in them. We may also make a distinction between usages and mores. Usages are folkways which contain no principle of welfare, but serve convenience so long as all know what they are expected to do. For instance, Orientals, to show respect, cover the head and uncover the feet; Occidentals do the opposite. There is no inherent and necessary connection between respect and either usage, but it is an advantage that there should be a usage and that all should know and observe it. One way is as good as another, if it is understood and established. The folkways as to public decency belong to the mores, because they have real connection with welfare which determines the only tenor which they can have. The folkways about propriety and modesty are sometimes purely conventional and sometimes inherently real. Fashions, fads, affectations, poses, ideals, manias, popular delusions, follies, and vices must be included in the mores. They have characteral qualities and characteral effect. However frivolous or foolish they may appear to people of another age, they have the form of attempts to live well, to satisfy some interest, or to win some good.
