In its social aspects, distinction may be made between planned change (as a designed, or purposive attempt by an individual, group, or larger social system to influence directly the status of itself, another system, or a situation), and unplanned change. A distinction also may be made between the transmission of culture (evolutionary changes of concern to the historical sciences and anthropology) and the transformation of social patterns. The former is neither planned nor intended, whereas through the latter, individuals, groups, or organizations change themselves or others through directive action or decisions.
Creating alternative societies has been practised throughout history. Most notably during the decline of the Roman Empire, the 17th century movement of European people to North America, and 20th century holism, human development and spiritual movements. It requires a (more or less) large number of people who are either consciously or unconsciously dissatisfied with the status quo. It also requires that the alternate forms are attractive enough to interest people in changing present habits and modes of operation. It requires that a group of people continually refine the forms to respond to the needs of change.
Mahatma Gandhi promoted positive social change [Sarvodaya], meaning "welfare for all", could be attained through action which was based upon truth [Satyagraha] and non-violence [Ahimsa].
2. Alternative society is useful in that it is a non-violent and organic way to create social change.
