The term _Sitte_ (mores) is a synonym of habit and of usage, of convention and tradition, but also of fashion, propriety, practise, and the like. Those words which characterize the habitual are usually regarded as having essentially unequivocal meanings. The truth is that language, careless of the more fundamental distinctions, confuses widely different connotations. For example, I find that custom--to return to this most common expression--has a threefold significance, namely: 1. _The meaning of a simple objective matter of fact._--In this sense we speak of the man with the habit of early rising, or of walking at a particular time, or of taking an afternoon nap. By this we mean merely that he is accustomed to do so, he does it regularly, it is a part of his manner of life. It is easily understood how this meaning passes over into the next: 2. _The meaning of a rule, of a norm which the man sets up for himself._--For example, we say he has made this or that a custom, and in a like meaning, he has made it a rule, or even a law; and we mean that this habit works like a law or a precept. By it a person governs himself and regards habit as an imperative command, a structure of subjective kind, that, however, has objective form and recognition. The precept will be formulated, the original will be copied. A rule may be presented as enjoined, insisted upon, imposed as a command which brings up the third meaning of habit: 3. _An expression for a thing willed, or a will._--This third meaning, which is generally given the least consideration, is the most significant. If, in truth, habit is the will of man, then this alone can be his real will. In this sense the proverb is significant that habit is called a second nature, and that man is a creature of habit. Habit is, in fact, a psychic disposition, which drives and urges to a specific act, and this is the will in its most outstanding form, as decision, or as "fixed" purpose.
