"Morals consist of political morals, commercial morals,..." - Quote by Mark Twain

“The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creatures that cannot.”

“It is a dear and lovely disposition, and a most valuable one, that can brush away indignities and discourtesies and seek and find the pleasanter features of an experience.”

“My father and I were always on the most distant terms when I was a boy--a sort of armed neutrality, so to speak. At irregular intervals this neutrality was broken, and suffering ensued; but I will be candid enough to say that the breaking and the suffering were always divided up with strict impartiality between us--which is to say, my father did the breaking, and I did the suffering.”

“Mercy detached from justice grows unmerciful.”

“There is a higher court than courts of justice and that is the court of conscience. It supercedes all other courts.”

“Labor to keep alive in your breast that little spark of celestial fire, called conscience.”

“Real integrity is doing the right thing, knowing that nobody's going to know whether you did it or not.”

“I am strongly in favour of using poisoned gas against uncivilised tribes.”

“People are getting smarter nowadays; they are letting lawyers, instead of their conscience, be their guide.”
