As people, we become addicted to knowing. We become addicted to the acquiring of knowledge. When we grasp a new concept, our brain releases a dose of chemicals similar to opium. Knowledge addiction gives the physical human a strong evolutionary advantage. We are guaranteed to progress if we are hard wired to learn. The human biological system, being a reflection of the greater universe (which is geared towards expansion), is essentially designed to maximize the rate at which new but understandable information is acquired. Once you have acquired a new bit of information, you spend your time learning something else. Without thinking about it, we pick out experiences that are new; experiences which cause us to know more. A biological addiction to know more is perfect design because it endows the physical human with a perpetuating beneficial learning behavior, even if misery and negative consequences are experienced along the way. This is helpful in an environment of contrast such as this.
