Some people with every bright promise in their life commit suicide. Suicide is not the culmination of a difficult life; it comes in from some hidden location beyond the mind and beyond consciousness. I can look back now at my own little para-suicidal period: the logic that seemed so abundantly reasonable to me at that time now seems as alien as the bacteria that gave me pneumonia a few years earlier. It is like a powerful germ that entered the body and took over. I had been hijacked by strangeness.
