Intelligence is one of the ...

Intelligence is one of the greatest human gifts. But all too often a search for knowledge drives out the search for love. This is something else I've discovered for myself very recently. I present it to you as a hypothesis: Intelligence without the ability to give and receive affection leads to mental and moral breakdown, to neurosis, and possibly even psychosis. And I say that the mind absorbed in and involved in itself as a self-centered end, to the exclusion of human relationships, can only lead to violence and pain.

Quotes from the same author

Remembering how my mother looked before she gave birth to my sister is frightening. But even more frightening is the feeling that I wanted them to catch me and beat me. Why did I want to be punished? Shadows out of the past clutch at my legs and drag me down. I open my mouth to scream, but I am voiceless. My hands are trembling, I feel cold, and there is a distant humming in my ears.

Dr. Strauss said I had something that was very good. He said I had a good motor-vation. I never ever knew I had that. I felt proud when he said that not every body with an eye-q of 68 had that thing. I don't know what it is or where I got it but he said Algernon had it too. Algernons motor-vation is the cheese they put in his box. But it can't be that because I didn't eat any cheese last week.
