In any case, this close relation between knowing and doing can help us to interpret one cause of the fear of knowing as deeply a fear of doing, a fear of the consequences that flow from knowing, a fear of its dangerous responsibilities. Often it is better not to know, because if you did know, then you would have to act and stick your neck out.
