Context

“The zeal for "answers" is the explanation of much of the zeal for rigid and mechanical methods. Forcing and overpressure have the same origin, and the same result upon alert and varied intellectual interest. Open-mindedness is not the same as empty-mindedness. To hang out a sign saying "Come right in; there is no one at home" is not the equivalent of hospitality. But there is a kind of passivity, willingness to let experiences accumulate and sink in and ripen, which is an essential of development.” source
