Those who tell you that man is unable to perceive a reality undistorted by his senses, mean that they are unwilling to perceive a reality undistorted by their feelings. "Things as they are" are things as perceived by your mind; divorce them from reason and they become "things as perceived by your wishes.
Ayn RandA morality that holds need as a claim, holds emptiness-non-existence-as its standard of value; it rewards an absence, a defect: weakness, inability, incompetence, suffering, disease, disaster, the lack, the fault, the flaw-the zero.
