“As the founder of modern behaviorism, Skinner did not attempt to understand the processes occurring within the individual; he had the reserve and prudence to consider the mind a “black box.” Once, in one of our conversations about the nature of the universe, about space and time, Skinner said, “I don’t know how you can think like that. I wouldn’t even know how to begin to think about the nature of space and time.“ His humility revealed his epistemological wisdom. However, I also saw in the softness of his glance the helplessness that the topic occasioned.”
