Dean Koontz. Midnight (№ 15730)

Sometimes quite nice to be one of the "brothers", thought Sam. To live guided by the senses, nothing to think about. Or take the same computer - the other extreme... the perfect electronic brain, cold calculation, and you are no feelings. No one except the people, bears the double burden of intelligence and feelings, it's scary complicates life; you are either constantly thinking about their feelings instead of acting on instinct or trying to understand what kind of feeling you have to experience in this situation. Your thoughts and opinions are inevitably colored by emotions - some of them are on the subconscious level, and you can't even fully understand why you chose a particular decision, or otherwise received. Feelings cloud the mind, but if you try to understand them, they slip away from you. To feel deeply and at the same time to think clearly is the same that to drive a unicycle on a wire, stretched at a dizzy height, and even while juggling six gymnastic clubs.
