The idea of self-emancipation through knowledge, which was the basic idea of the Enlightenment, is in itself a powerful enemy of fanaticism; 
for it makes us try hard to detach ourselves or even to dissociate ourselves from our own ideas (in order to look at them critically) instead of identifying ourselves with them.  
And the recognition of the sometimes overwhelming historical power of ideas should teach us how important it is to free ourselves from the overpowering influence of false or wrong ideas. 
In the interests of the quest for truth and of our liberation from errors we have to train ourselves to view our own favourite ideas just as critically as those we oppose.

― Karl Popper
