Marcus Aurelius combines reason with beautiful sentiment. His emotion is always accompanied by thought. Here, for instance, is a noble passage on the social commonwealth--"For we are made for co-operation, like feet, like hands, like eyelids, like the rows of the upper and lower teeth. To act against one another then is contrary to nature; and it is acting against one another to be vexed and to turn away." In a still loftier passage he says--and let us remember he says it to himself, not to an applauding audience, but quietly, and with absolute truth, and no taint of theatricality--"My nature is rational and social; and my city and country, so far as I am Antoninus, is Rome; but so far as I am a man, it is the world." In his brief, pregnant way, he states the law of human solidarity--"That which is not good for the swarm, neither is it good for the bee." And who could fail to appreciate this sentiment, coming as it did from the ruler of a great empire?--"One thing here is worth a great deal, to pass thy life in truth and justice, with a benevolent disposition even to liars and unjust men." Here again, it is the fashion in some circles, to pretend that Marcus Aurelius was influenced by the spread of Christian ideas. George Long, however, speaks the language of truth and sobriety in saying, "It is quite certain that Antoninus did not derive any of his Ethical principles from a religion of which he knew nothing." To say as Dr. Schmidt does that "Christian ideas filled the air" is easy enough, but where is the proof? No doubt the Christian writers made great pretensions as to the spread of their religion, but they were notoriously sanguine and inaccurate, and we know what value to attach to such pretensions in the second century when we reflect that even in the fourth century, up to the point of Constantine's conversion, Christianity had only succeeded in drawing into its fold about a twentieth of the inhabitants of the empire. Enough has been said in this article to show that the idea of our common humanity is not "a purely Christian conception," that it arose in the natural course of human development, and that in this, as in other cases, the apologists of Christianity have simply appropriated to their own creed the fruits of the political, social, and moral growth of Western civilisation. THE SONS OF GOD. "The sons of God saw the daughters of men that they were fair." --Genesis vi. 8. According to the first book of the Bible, the earth fell into a very wicked condition in the days of the patriarchs. God made everything good, but the Devil turned everything bad; and in the end the Lord put the whole concern into liquidation. It was a case of universal bankruptcy. All that was saved out of the catastrophe was a consignment of eight human beings and an unknown number of elephants, crocodiles, horses, pigs, dogs, cats, and fleas.
