Can Positive Thinking Cure Disease?

Where The Secret gets a bit esoteric is in its attempt to explain why bad things happen to good people. This certainly isn’t a new question that can Positive Thinking cure disease. Countless philosophers and theologians have tried to understand the problem of evil for centuries – or at least as long as ethical monotheism has been around. To frame the question, how can evil exist in a world if there is an omnipotent, omnipresent God? Or, in the language of The Secret, if the universe is a large catalog and all you have to do is pick out what you want, why is it that some of us seem to choose bad things like cancer, rape, and natural disasters? Why is it that some of us never seem to lose weight, no matter how hard we try? Why can’t some of us get out of debt – or at least make enough to cover our monthly expenses?
The Secret claims it’s because we have all these negative beliefs that are poisoning our lives. As we focus on getting out of debt, we filter out all but “debt”. As we focus on curing ourselves from disease, we filter out all but “disease”. It’s these thoughts that are creating the problems in our lives.
