The Sorites Paradox, "life," and Abiogenesis

Abstract

The ancient Greek philosopher Eubulides of Miletus drew attention to the impossibility of defining a point of transition between two states or conditions at opposite ends of a continuum. The ensuing "drawing the line" conundrum - the sorites paradox - arises from the vague predicates which humans use to convey concepts. It is argued that "life" is an indeterminate concept subject to the vagaries of the paradox. Science communicators and educators need to refrain from phraseology which connotes a sharp line of demarcation between nonliving and living or the existence of a discrete moment in time at which life appeared.
