The fact that a man has no claim on others ... does not preclude or prohibit good will among men and does not make it immoral to offer or to accept voluntary, non-sacrificial assistance.
Ayn RandLive and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.
Ayn RandA rational mind does not work under compulsion; it does not subordinate its grasp of reality to anyone's orders, directives, or controls; it does not sacrifice its knowledge, its view of the truth, to anyone's opinions, threats, wishes, plans.
