Aurelius acquired the reputation of a philosopher king within his lifetime and the title would remain after his death; both Lucius Cassius Dio and the biographer call him "the philosopher". Christians such as Justin Martyr Athenagoras and Eusebius also gave him the title.The latter went so far as to call him "more philanthropic and philosophic" than Antoninus and Hadrian and set him against the persecuting emperors Domitian and Nero to make the contrast bolder. This book is the other translation of the Aurelius book in the Karbon Kitaplar by George Long.

A man should always have these two rules in readiness; the one to do only whatever the reason of the ruling and legislat­ing faculty may suggest for the use of men; the other to change thy opinion if there is any one at hand who sets thee right and moves thee from any opinion. But this change of opinion must proceed only from a certain persuasion as of what is just or of common advantage and the like not because it appears pleasant or brings reputation.
― Marcus Aurelius
