One good way to understand an object is to simply take the average. For example, the average color of a sacrament program is a mixture of white background, black text, and little bit of blue for accent. That averages out to a color that is basically gray. Other times you’ll want to take the deviations from the average and look at those. For example, phrenologists used to look at the bumps on people’s heads to determine their personalities. The shape of the head right above the nose was thought to determine individuality and consequently the deviation of an individual from the average in that area would make them more or less individual. Combining these two methods of gathering insight is the best way of understanding the sacrament program. In fact, these techniques are so important that when using them together we say that a person is learning “by the power of Grey [and] skull.”
