is the personality, or character, of the understanding as it dictates behaviour.
Must be either:
Selfish: Where the set of beliefs reveres "Me" ahead of all other considerations, including truth, which becomes what private fears and fancies demand, so the understanding is Insane.
Unselfish: Where the set of beliefs reveres "Us", the community, ahead of all other considerations, which in turn demands that private fears and fancies be ignored in realising truth, so the understanding is Sane.
Cause and Effect (Science) decided by the beliefs that are the experience, or knowledge, of the understanding. They are collected and refined throughout the life of the understanding and stored in memory. This accumulation of knowledge allows the recognition of patterns in the knowledge, which results in the development of Abstract Tools that enhance the power of the understanding, such as: Recognition of truth from falsity; Logic; Mathematics.
