J. M. Robertson,
A Short History of Christianity
“ The one emperor after Marcus Aurelius who attracts us as a human being and as a mind, he set himself a task which, whether he failed or succeeded, must lift his name high in the annals of a decadent civilization: his failure, in fact, makes him the most living figure in the long line of autocrats from Constantine to Charlemagne. It is by such contrast, indeed, that he becomes eminent. Measured by the standards of progressive civilizations, against the great minds of the pre-imperial world and the best statesmen of later realms, he is neither a great ruler nor a great intelligence. ”
