For Such Moments as This

"I will keep the law given by God; sanctioned by man. I will hold to the principles received by me when I was sane, and not mad--as I am now. Laws and principles are not for times when there is no temptation: they are for such moments as this, when body and soul rise in mutiny against their rigour; stringent are they; inviolate they shall be. If at my individual convenience I might break them, what would be their worth? They have a worth--so I have always believed; and if I cannot believe it now, it is because I am insane--quite insane: with my veins running fire, and my heart beating faster than I can count its throbs. Preconceived opinions, foregone determinations, are all I have at this hour to stand by: there I plant my foot." --Jane Eyre (emphasis mine)
