The science fiction writer Arthur C. Clarke remarked that "any sufficiently advanced technology is indistinguishable from magic". Clarke was referring to the fantastic inventions we might discover in the future or in our travels to advanced civilizations. However, the insight also applies to self-perception. When we turn our attention to our own minds, we are faced with trying to understand an unimaginably advanced technology. We can't possibly know (let alone keep track of) the tremendous number of mechanical influences on our behavior because we inhabit an extraordinarily complicated machine. So we develop a shorthand, a belief in the causal efficacy of our conscious thoughts. We believe in the magic of our own causal agency.
