For men whose ambition neither seas nor mountains, nor unpeopled deserts can limit, nor the bounds dividing Europe from Asia confine their vast desires, it would be hard to expect to forbear from injuring one another when they touch, and are close together.

Context

“But Lysimachus now arriving, and claiming the defeat of Demetrius as the joint exploit of them both, and that therefore the kingdom should be shared between them, Pyrrhus, not as yet quite assured of the Macedonians, and in doubt of their faith, consented to the proposition of Lysimachus, and divided the country and cities between them accordingly. This was for the present useful, and prevented a war; but shortly after they found the partition not so much a peaceful settlement, as an occasion of further complaint and difference. For men whose ambition neither seas nor mountains, nor unpeopled deserts can limit, nor the bounds dividing Europe from Asia confine their vast desires, it would be hard to expect to forbear from injuring one another when they touch, and are close together. These are ever naturally at war, envying and seeking advantages of one another, and merely make use of those two words, peace and war, like current coin, to serve their occasions, not as justice but as expediency suggests, and are really better men when they openly enter on a war, than when they give to the mere forbearance from doing wrong, for want of opportunity, the sacred names of justice and friendship.” source
