Everything in life is done for an effect that a man hopes to be positive to his fate, and the effects that dwell heaviest as motives in his heart decides the quality of his enduring character. Psychological laws run parallel to the physical ones we study by means of science and practical observation. For instance, the greater the presence of something in terms of mass, the greater the gravity or influence it has on everything else. So the greater the frequency, duration and depth a particular motive has on a man’s mind, the greater its influence on every other motive. His psychological framework gradually structures itself around this center of intention, and whatever motives lie there have a complementary nature to one another. In most cases, if not all, this is the home of unabashed self-interest, in which its corrupted children of lust, gluttony, greed, sloth, wrath, envy, and pride — the seven deadly sins — have their root. Beyond the simple motive of ensuring basic survival, these deranged derivates of sincere self-interest corrupt the nature of a man’s psychology to become what is a caricature of what he could have been, and perhaps still might be if a great deal of honest introspection, and a real struggle to change, takes place.
