Personality has different meanings

Personality has different meanings for theologians, philosophers, and
sociologists, and within psychology it has been defined in many ways
(Allport, 1937). Rather than give examples of the diversity of the definitions,
which tends to be confusing rather than illuminating, we will begin by
considering just one definition of personality considered acceptable by many
psychologists today (Block, Weiss and Thorne, 1979): personality refers
to ‘more or less stable, internal factors that make one person’s
behaviour consistent from one time to another, and different from the
behaviour other people would manifest in comparable situations’
(Child, 1968, p.83).
