But, returning to the matter in hand, it may be said, that if the judgment of men be at fault in pronouncing whether the present age or the past is the better in respect of things whereof, by reason of their antiquity, they cannot have the same perfect knowledge which they have of their own times, it ought not to be at fault in old men when they compare the days of their youth with those of their maturity, both of which have been alike seen and known by them. This were indeed true, if men at all periods of their lives judged of things in the same way, and were constantly influenced by the same desires; but since they alter, the times, although they alter not, cannot but seem different to those who have other desires, other pleasures, and other ways of viewing things in their old age from those they had in their youth. For since, when they grow old, men lose in bodily strength but gain in wisdom and discernment, it must needs be that those things which in their youth seemed to them tolerable and good, should in their old age appear intolerable and evil. And whereas they should ascribe this to their judgment, they lay the blame upon the times. But, further, since the desires of men are insatiable, Nature prompting them to desire all things and Fortune permitting them to enjoy but few, there results a constant discontent in their minds, and a loathing of what they possess, prompting them to find fault with the present, praise the past, and long for the future, even though they be not moved thereto by any reasonable cause. I know not, therefore, whether I may not deserve to be reckoned in the number of those who thus deceive themselves, if, in these Discourses of mine, I render excessive praise to the ancient times of the Romans while I censure our own. And, indeed, were not the excellence which then prevailed and the corruption which prevails now clearer than the sun, I should proceed more guardedly in what I have to say, from fear lest in accusing others I should myself fall into this self-deception. But since the thing is so plain that every one sees it, I shall be bold to speak freely all I think, both of old times and of new, in order that the minds of the young who happen to read these my writings, may be led to shun modern examples, and be prepared to follow those set by antiquity whenever chance affords the opportunity. For it is the duty of every good man to teach others those wholesome lessons which the malice of Time or of Fortune has not permitted him to put in practice; to the end, that out of many who have the knowledge, some one better loved by Heaven may be found able to carry them out. Having spoken, then, in the foregoing Book of the various methods followed by the Romans in regulating the domestic affairs of their city, in this I shall speak of what was done by them to spread their Empire. CHAPTER I.—_Whether the Empire acquired by the Romans was more due to Valour or to Fortune_.
