I'm not advocating pure reason. I'm advocating using reason in place of faith. Both are means of deciding what is true about the world, the value of which is in deciding what course of action will facilitate your tastes, desires, dreams, and emotions. Managing life in a way that facilitates desirable experiences and minimizes the undesirable ones is our primary goal in life, not reasoning. Reasoning is a means to achieve and preserve that goal. Or faith. Take your pick.
I just finished watching a true crime television show about an elderly man that was robbed of his fifteen million dollars by a psychic. He had faith in her honesty. He trusted her by faith rather than evidence. He didn't reason. He didn't seek evidence. And he got fleeced. Once, his emotional status was excellent. He was financially secure, at peace, and living the life of a tree farmer in Oregon who was well-liked by those who knew him.
Now, he's broke, alone, financially insecure, and feeling like an old fool because he made decisions based on faith rather than reason applied to evidence. That's what reason is good for, and why it should always be the method one used to make decisions. But it is not an end. It is the means to an end.
The emotions are a horse, reason the reins. Emotions are the color palette, reason the artist who manipulates the colors and gives them meaning. Reason is the gardener that arranges the landscaping to be beautiful and functional.
Thought serves feeling. Feeling is where we live. Without it, reason cannot serve us. Without feeling, people often want to die, even if the reasoning faculty remains intact. It's useless without feelings to shape.
So no to a world of pure reason, and yes to a world of good experiences thanks to reasoning well.
