"Do you ask what moral obligation I owe to my fellow men? None—except the obligation I owe to myself, to material objects and to all of existence: rationality. I deal with men as my nature and theirs demands: by means of reason. I seek or desire nothing from them except such relations as they care to enter of their own voluntary choice. It is only with their mind that I can deal and only for my own self-interest, when they see that my interest coincides with theirs. When they don’t, I enter no relationship; I let dissenters go their way and I do not swerve from mine. I win by means of nothing but logic and I surrender to nothing but logic. I do not surrender my reason or deal with men who surrender theirs."
