A symbol is a sign that denotes its object solely by virtue of the fact that it will be interpreted to do so. The symbol consists in a natural or conventional or logical rule, norm, or habit, a habit that lacks (or has shed) dependence on the symbolic sign's having a resemblance or real connection to the denoted object. Thus, a symbol denotes by virtue of its interpretant. Its sign-action (semeiosis) is ruled by a habit, a more or less systematic set of associations that ensures its interpretation.
