The human mind in the act of knowing must break sufficiently free from the hold that confirmation bias has on its search for truth. We should not merely seek out data we want to find to confirm our beliefs, as this may lead us to faulty conclusions. Since it is beliefs that ultimately control our actions, and we realize emotions mostly control our beliefs, how can we use rationale to control our emotions? Is anyone really good with this? None that I know. Only from the most remote abstract thought outside a single interlocked system of beliefs we inwardly protect does there remain anything except this: Control your mind, or it controls you. Only if you are uncommitted to the view that reason (which originates in the mind) is a comparatively recent development would you ever doubt this integral importance of interweaving what you know to be true with what you need to believe is true.
