This difference in the spirit, rather than the letter, of their philosophy is to be attributed in some degree to this, that Lucretius was a Roman of the antique type of Ennius, born with the passionate heart of a poet, and inheriting the resolute endurance of the great patrician families. Partly too, as was said before, the effect of the speculative philosophy which he embraced was to deepen and strengthen that mood of imaginative contemplation, which he shares, not with any of his countrymen, but with a few great thinkers of the world. It is his philosophical enthusiasm which distinguishes the teaching of Lucretius from the meditative and practical wisdom which has made Horace the favourite Epicurean teacher and companion of modern times. Partly too, as was said in a former chapter, this new aspect of Epicureanism in Lucretius may be attributed to the reaction of his nature from the confusion of the times in which he lived. It is not indeed possible to learn whether the passions of his age first drove him to Epicureanism, or whether the doctrines of that philosophy, adopted on speculative grounds, may not rather have led him to regard his age in the spirit of contemplative isolation, which he has described in the well-known passage-- Suave, mari magno turbantibus aequora ventis, etc. His philosophy may have been forced on him by personal experience, or the intimations of experience may have assumed their form and colour from the nature of his philosophy. But the memories of his youth and the experience of things witnessed in his manhood did undoubtedly colour all his thoughts and feelings on human life. Some of the forms of evil against which he contends had never been so prominently displayed before. Yet all these considerations afford only a partial explanation of the character of his practical philosophy. There were other Roman Epicureans, contemporary with him and later, and none are known to have been in any way like him. Although his nature was made of the strong Roman fibre; although his mind had been deeply imbued with the spirit of Greek philosophy; although his view of life was necessarily coloured by the action of his times; yet all these considerations go but a little way to explain his attitude of mind and the work which he accomplished in the world. Over all these considerations this predominates, that he was a man of great original and individual force, and one who in power and sincerity of thought and feeling rose higher than any other above the level of his age and country.
