Change is the only constant – Isaac Asimov
Can the above quote be called an example of antithesis or that of oxymoron, or neither of these? I am confused because both antithesis and oxymoron have a contrasting effect.
Antithesis: A rhetorical term for the juxtaposition of contrasting ideas in balanced phrases or clauses.
Oxymoron: A figure of speech in which incongruous or seemingly contradictory terms appear side by side; a compressed paradox.
