Seneca, like Tacitus, has a remarkable power of moral diagnosis. He had acquired a profound, sad knowledge of the pathology of the soul. It was a power which was almost of necessity acquired in that time of terror and suspicion, when men lived in daily peril from seeming friends. There never was a period when men more needed the art of reading the secrets of character. Nor was there ever a time when there were greater facilities for the study. Life was sociable almost to excess. The Roman noble, unless he made himself deliberately a recluse, spent much of his time in those social meeting-places of which we hear so often,(28) where gossip and criticism dealt mercilessly with character, where keen wits were pitted against one another, sometimes in a deadly game, and where it might be a matter of life or death to pierce the armour of dissimulation.(29) Seneca had long shone in such circles. In his later years, if he became a recluse, he was also a spiritual director. And his Letters leave little doubt that many a restless or weary spirit laid bare its secret misery to him, for advice or consolation. Knowing well the wildest excesses of fantastic luxury, all the secrets of the philosophic confessional, the miseries of a position oscillating between almost princely state and monastic renunciation, the minister of Nero, with a self-imposed cure of souls, had unrivalled opportunities of ascertaining the moral condition of his class.
Seneca is too often a rhetorician, in search of striking effects and vivid phrase. And, like all rhetoricians, he is often inconsistent. At times he appears to regard his own age as having reached the very climax of insane self-indulgence. And yet, in a calmer mood, he declares his belief that the contemporaries of Nero were not worse than the contemporaries of Clodius or Lucullus, that one age differs from another rather in the greater prominence of different vices.(30) His pessimism extends to all ages which have been allured by the charm of ingenious luxury from the simplicity of nature. In the fatal progress of society, the artificial multiplication of human wants has corrupted the idyllic innocence of the far-off Eden, where the cope of heaven or the cave was the only shelter, and the skin-clad savage made his meal on berries and slaked his thirst from the stream.(31) It is the revolutionary dream of Rousseau, revolting from the oppression and artificial luxury of the _Ancien Régime_. Seneca’s state of nature is the antithesis of the selfish and materialised society in which he lived. Our early ancestors were not indeed virtuous in the strict sense.(32) For virtue is the result of struggle and philosophic guidance. But their instincts were good, because they were not tempted. They enjoyed in common the natural bounties of mother earth.(33) Their fierceness of energy spent itself on the beasts of the chase. They lived peaceably in willing obedience to the gentle paternal rule of their wisest and best, with no lust of gold or power, no jealousy and hatred, to break a contented and unenvious harmony. The great disturbers of this primeval peace were avarice and luxury.(34) The moment when the first nugget flashed its baleful temptations on the eyes of the roaming hunter was the beginning of all human guilt and misery.(35) Selfish greed, developing into insatiable appetite, is the original sin which turned the garden into wilderness. In individualist cravings men lost hold on the common wealth of nature. Luxury entered on its downward course, in the search for fresh food and stimulus for appetite, till merely superfluous pleasures led on to those from which untainted nature recoils.(36) Man’s boasted conquests over nature, the triumphs of his perverted ingenuity, have bred an illimitable lust, ending in wearied appetite; they have turned those who were brothers into cunning or savage beasts.
