“Another thing he wondered at in the _Yahoos_, was their strange disposition to nastiness and dirt; whereas there appears to be a natural love of cleanliness in all other animals.” As to the two former accusations, I was glad to let them pass without any reply, because I had not a word to offer upon them in defence of my species, which otherwise I certainly had done from my own inclinations. But I could have easily vindicated humankind from the imputation of singularity upon the last article, if there had been any swine in that country (as unluckily for me there were not), which, although it may be a sweeter quadruped than a _Yahoo_, cannot, I humbly conceive, in justice, pretend to more cleanliness; and so his honour himself must have owned, if he had seen their filthy way of feeding, and their custom of wallowing and sleeping in the mud.
My master likewise mentioned another quality which his servants had discovered in several Yahoos, and to him was wholly unaccountable.

And the only remedy they found was, to set him to hard work, after which he would infallibly come to himself.” To this I was silent out of partiality to my own kind; yet here I could plainly discover the true seeds of spleen, which only seizes on the lazy, the luxurious, and the rich; who, if they were forced to undergo the same regimen, I would undertake for the cure.
