In Sillam (44)

When I this proposition had defended,
"A coward cannot be an honest man,"
Thou Silla, seem'st forthwith to be offended,
And holds the contrary, and sweares he can;
But when I tell thee that he will forsake
His dearest friend, in perill of his life;
Thou then art chang'd, and sayst thou didst mistake,
And so we end our argument and strife:
Yet I think oft, and thinke I thinke aright,
Thy argument argues thou wilt not fight.
