Kindness is preserved by a constant reciprocation of benefits or interchange of pleasures; but such benefits only can be bestowed, as others are capable to receive, and such pleasures only imparted, as others are qualified to enjoy.

So do the antagonisms of these principles in the broader field of society equally conceal a fundamental reciprocation.

What then can ensue but a continual exacerbation of hatred, an unextinguishable feud, an incessant reciprocation of mischief, a mutual vigilance to entrap, and eagerness to destroy.

An assurance of unfading laurels, and immortal reputation, is the settled reciprocation of civility between amicable writers.

That conduct which betrays designs of future hostility, if it does not excite violence, will always generate malignity; it must for ever exclude confidence and friendship, and continue a cold and sluggish rivalry, by a sly reciprocation of indirect injuries, without the bravery of war or the security of peace.
