This paper reviews and evaluates various theories of the origins of theory of mind in infancy. In what a theory of mind consists is first considered. It is argued that any theory of mind has two important features. Firstly, a theory of mind recognizes, at least, the existence of psychological relations between agents and objects, including some relations which involve “action at a distance”. Secondly, in a theory of mind, self and other are equivalent in that both can act equally as agents of psychological relations. Any theory of the development of theory of mind must explicate how it is possible to acquire an understanding of these two features. With this requirement in mind, four main types of recent theories are considered — modularity theories, Piagetian theories, matching theories, and intersubjectivity theories. While no decision is made amongst these theories, suggestions for further improvement in theorizing on this topic are presented.
