But real fear, real terror is not so much fun. It can be educational and it can save your life, as Hannah Arendt says "Fear is an emotion indispensable for survival". In our ancestral environment fear was adaptive; the angel on our shoulder warning us of imminent threat. Even today fear continues to be our constant guardian, the sentinel of safety that helps to ensure a long, healthy life. I am a big fan of fear.
But as is the way with all good things fear all to often simply paralyses. It acts like an iron cage upon our hearts and minds, as Samuel Butler opined "Fear is static that prevents me from hearing myself" and fear is a hungry monster, a yaffling Greedygut constantly whispering to us in honeyed tones "Feed me, feeeeed me".
