"Whether they can be known to a supernatural being hinges on the effects of the prayers' solicitations as judged by proper scientific studies. To date, such studies of intercessory prayer have not shown it to improve health-care outcomes. In contrast to thoughts themselves, the brain activity from which thoughts arise does consist of energy—electrochemical energy within neural circuitry. Reading this teeming energy in millions of circuit neurons and translating it into the thought or prayer arising from it seems theoretically impossible for even a supernatural being." By David C. Haas, Committee for Skeptical Inquirer (March/April 2007)
