human beings share with other animals their dependence on bodily rhythms and rituals, such as abluting, feeding, and mating. They are also liable to become routinised and addicted. Education is a process during which they are brought within voluntary order and control. However, biological determinants continue to maintain conscious and unconscious parameters, including eg the timing of excretions. The existence of such determinants and drives is often invoked as a parallel to control exercised by other activities. These include potentially more pleasurable ones such as alcohol and drug use, bodily exercise, gambling, sexual activity, and sun bathing; or their opposites in deliberate self-harming. They can each be habit forming and potentially addictive, the more so when pursued to excess.
The matter of morality comes into play in two main regards. One is that of the consequences in terms of risk and harm for the performer and for those being interacted with (liberty-limiting principles). The other is damage to their own personal being - diminution in the individual humanity of their life. The addictive potential of any human being does entail susceptibility to unconscious as well as conscious drives. Moral education has as a central priority the heightening of awareness in regard to this aspect of the human condition.
