If you be carved with any thing […] which you do not like, conceal (as much as in you lieth) your repugnancies, and receive it however: And though your disgust many times is invincible, and it would be insufferable tyranny to require you should eat what your stomach nauseates; yet it will shew your civility to accept it, though you let it lye on your plate, pretending to eat, till you meet with a fit opportunity of changing your plate, without any palpable discovery of your disgust.

The quality of being repugnant: (logical) opposition, contradiction, incompatibility.

Resistance, fighting back.

Why do fond men expose themselves to battle, And not endure all threats? sleep upon’t, And let the foes quietly cut their throats, Without repugnancy?
