Life has the name of life, but in reality it is death.

Heraclitus of Ephesus (late 6th–early 5th century BCE) is known almost entirely through fragments preserved by later writers. The saying is typically treated as one of his paradoxical, aphoristic fragments contrasting appearance and reality and stressing the unity of opposites—life and death, waking and sleeping, youth and age. In the intellectual milieu of early Greek philosophy, Heraclitus challenged ordinary language and common sense by arguing that what we call stable “things” are processes and transformations. The line belongs to the tradition of fragmentary transmission: it is not from a surviving Heraclitean book as such, but from later quotation or paraphrase in ancient sources.

The statement turns on Heraclitus’s characteristic reversal: names and conventional categories mislead. What people call “life” is, in a deeper sense, inseparable from death—either because living is a continual dying (constant change and loss), or because life and death are mutually defining phases of one process. The point is not mere pessimism but metaphysics: reality is flux, and opposites interpenetrate. By exposing the gap between “name” (nomos, convention) and “reality” (physis, nature), the fragment urges readers to distrust surface labels and to see existence as transformation rather than a fixed state.
