“Think about it. There are some phrases that just wouldn’t appear in the English language:* ‘I chose not to be angry.’ ‘He plans to fall in love at 4.30pm tomorrow.’ ‘She decided that she was no longer to feel uneasy in his presence.’ ‘From that moment on, she determined no longer to be afraid of heights.’* ‘He decided to like spiders and snakes.’ Things like this are not under our direct control, but are rather the product of instinctive and automatic emotions. There is a good evolutionary reason why we are imbued with these strong, involuntary feelings: feelings can be inherited, whereas reasons have to be taught, which means that evolution can select for emotions much more reliably than for reasons. To ensure your survival, it is much more reliable for evolution to give you an instinctive fear of snakes at birth than relying on each generation to teach its offspring to avoid them. Things like this aren’t in our software – they are in our hardware.”
