Autonomy means acting on reasons I have chosen; but the lesson of cognitive science is that there is no self to do the choosing. We are far more like machines and wild animals than we imagine. But we cannot attain the amoral selflessness of wild animals, or the choiceless automatism of machines. Perhaps we can learn to live more lightly, less burdened by morality. We cannot return to a purely spontaneous existence. If humans differ from other animals, it is partly in the conflicts of their instincts. They crave security, but they are easily bored; they are peace-loving animals, but they have an itch for violence; they are drawn to thinking, but at the same time they hate and fear the unsettlement thinking brings. There is no way of life in which all these needs can be satisfied. Luckily, as the history of philosophy testifies, humans have a gift for self-deception, and thrive in ignorance of their natures.
John Gray (philosopher)
