There Is Nothing Impossible To Him

This saying is attributed to Alexander the Great in the tradition of Plutarch's Life of Alexander, where Alexander is described as believing "nothing impossible for a valiant man." The precise modern phrasing appears to be a loose English paraphrase popularized in 19th-century motivational literature rather than a verbatim ancient text. Aristotle instilled in Alexander from an early age a conviction that great deeds were within reach of the sufficiently daring — a belief Alexander proved repeatedly across campaigns stretching from Greece to the borders of modern India.
