mens conscia recti
Mounser Green quotes Vergil, “a mind aware of what is right.” Mr. Gotobed has insulted Green by implying that he doesn’t work hard enough. Green desires to assert his class status and nationality over Mr. Gotobed and attempts to do this through this Latin phrase, which becomes a defense mechanism. In Green’s eyes, if Mr. Gotobed were an equal of Green, he would understand this phrase. However, Mr. Gotobed states that he understands “English pretty well…but I don’t go beyond that.” [KS & RR 2012]
