One of the significant lessons of the 20th Century intellectual history is the limitation of great minds and ideas, the inability and failure of some of the brightest thinkers to comprehend the consequences of their grand ideas, designed with great thought and benevolent intentions.

Perhaps the environment changed faster than their underlying assumptions could adapt, especially when these ideas become embedded in political structure.  Perhaps treating people like inputs in a model or herds of animals corralled and shepherded by intellectual elites is bound to meet resistance or disaster.

The key difference between intellect and wisdom is humility and the understanding of limits.
